Basics on Welding

master5 years ago07 mins

Welding is a process of joining materials such as metals and plastics using heat or pressure. It is the most popularly used method today to join metals, and is used extensively in the production of automobiles, ships, trains, buildings, and bridges. Compared to soldering and brazing which introduce a soft melted substance to hold original pieces together, welding process melts the metals together to form a robust and a strong join.
Welding had been practiced since ancient days. The most popular method during this era was forge welding that cnc machine selection criteria was used by blacksmiths. This method used to weld two metals by beating them together over a hot coal.
Today, the modern technologies have allowed welders to work with much greater precision and achieve stronger welds compared to olden days. The first World War gave the impetus for the development of welding technologies, as many countries were looking for better and efficient ways of welding ships and planes for the war. From there onwards, welding technology developed into indian wood industry a modern art which could be performed manually as well as using robotic machines. In particular, it can be performed under different environmental conditions such as underwater, on-site and in workshops. In spite of these rapid advances, welding seems a highly risky and a dangerous process which can expose a welder to burns, poisonous or toxic gases and even eye damage.
Most common methods of welding practiced today are gas, arc, spot, resistance, electron beam, laser and robot welding.
Gas welding is commonly referred as Oxyacetylene where gas and oxygen are mixed together to produce a high temperature flame at the torch to melt the edges of metal that have to be welded. Hence, Oxyacetylene welding usually requires two tanks or bottles to store oxygen and the fuel acetylene. This method is one of the oldest techniques used and still practiced all over the world. This is mainly because the equipment including storage bottles are easily portable. This is extensively used for joining pipes and simple fabrication.
Arc welding uses an electrical arc between an electrode and the subject material and at the same time melting them together to create a strong bond or a weld. Arc welding is extensively used in industrial applications because it’s economical. The problem with the arc process is that sometimes welds can become brittle and weak due to oxygen and nitrogen present in the atmosphere. To overcome this problem, shielded gas such as hydrogen, argon and helium are used.
Resistance welding uses physical pressure and heat to weld materials. The heat is generated by the resistance of high electrical current passing through the materials that have to be welded. This method is popular among many industrial applications because it is easily automated and economical at high volumes of production. Due to its high initial investment cost it may not be feasible to use on low production volumes.
Spot welding is another form of resistance welding which is used to join …

Identifying An Instrumentation Job
In the course of many mechanical engineering projects, instrumentation plays a large role in the operating systems of equipment. Instrumentation in these cases refers to power boards, schematic systems and other electronic equipment designed to control or monitor the operation of a full-scale system. These systems may be related to industrial equipment, HVAC or electric and nuclear generating power facilities.
An instrumentation job can be related to the design or implementation of complete electronic instrumentation or it may be operational in the sense that the instrumentation requires regular monitoring, testing and maintenance. A degree in electrical engineering and instrumentation is required for most such jobs.
Where To Find Instrumentation Jobs
When preparing an instrumentation job search, it’s advisable to determine the specific area of expertise and correlate that to the types of industries that offer positions for instrumentation specialists. Hands on jobs in the instrumentation field may mean designing calibrators, meters, imaging cameras for medical and industrial equipment, controls that are operated through a PC system or programmable logic controller (PLC) or transformers for relaying interchangeable electrical currents or other forms of power operations.

Teaching Over Technology – How to Talk to Your Digitally-Distracted Student

master5 years ago06 mins

Word Association is a fun game. Player #1 says a word – banana, for example – and Player #2 says the very first word that comes to mind – split – and so on. If I were to start this game with any given parent or teacher, it would very likely go something like this:
Me: Black…
Parent/Teacher:…Berry!
Me: Face…
P/T:!
And so on. Years ago, the word “black” would most likely have triggered words like “white” and “board,” but today the more likely association is “berry,” referring to one of the leading brands of do-it-all devices making their way into the hands of people all over the world. Here in the United States, some of those people are school-aged children and teenagers, members of a generation born well into the computer age. Consequently, both teachers and parents are finding it increasingly difficult to fight – let alone win – the battle for kids’ attention against an opponent that is constantly growing, improving, and becoming easier to access: technology. As students gain better knowledge of – and easier access to – devices such as MP3 players and smart phones, they focus more on their digital activity than on their schoolwork, whether at home or in the classroom.
Often referenced since its publication earlier this year, a study conducted by the Kaiser Family Foundation found that “heavy media use [among youths aged 8 to 18 years] is associated with several negatives, including behavior problems and lower grades…confirm[ing] the fears of many parents whose children are constantly tethered to media devices.”
Unfortunately, the prevalence of these devices in our society is growing by the day, and the younger generation is gaining the upper hand as they enter into adulthood, thanks to a familiarity with modern technology gained far earlier in life than is the case for their predecessors. Nonetheless, many (if not most) adults use some type of media device on a regular basis, and of these adults, it’s the parents of very young children who seem to be the cause for concern – at least for child development experts.
Fear not, parents and teachers! While technology is inevitably reaching more and more children each day, your ability to help these children, these students, is as strong as ever. In fact, there is no need to think of your effort as a fight, and no need to think of technology as an opponent. Remember, you have the advantage of knowing how society was able to function without smart supply and demand in spanish phones, MP3 players, and laptops, as well as how society is able to function with them. This frame of reference gives you the ability to teach your kids what you already know: As much as society grows and changes in order to better itself and preserve its existence, there are certain things that remain the same over time, like the foundations of a well-rounded education.
Consider using educational games and learning aids to help you get started – work …

What Is Mig Welding?

master5 years ago05 mins

Metal Inert Gas welding – better known as MIG welding- is a welding process pioneered in 1948 by the Battelle Memorial Institute, a non-profit science and development company based in Ohio, USA. Otherwise known as Gas Metal Arc Welding, the MIG technique was principally developed to weld aluminium, as well as other non-ferrous metals. MIG weldingis an automatic or semi-automatic process, which uses electrode-based welding equipment to fuse metal together. Inert gas also passes through the welding gun, acting as a shield which keeps the weld zone free of air-borne contaminants.
When put side by side with the old-fashioned ‘stick welding’ techniques, MIG welding is capable of fusing metal together extremely quickly. This is why the process has become so popular, as it is perfect for welding soft metals. Initially, MIG welding supplies were quite expensive to buy, which made the process impractical for welding steel in mass production manufacturing. The first MIG welding guns created a gas shield using argon, which was costly to obtain. However, MIG welding techniques have steadily improved over time, and semi-inert gases like carbon dioxide can now be used for shielding, which has made the process cost effective for mainstream use.
As well as enabling the welding of non-ferrous metals, MIG welding also has a number of other advantages compared to traditional techniques. MIG welding can produce continuous welds much faster and longer 3569 mfg general industrial machinery than other processes, and creates much cleaner welds with far less unwanted splatter. The technique is also extremely versatile, and can be used to weld a wide range of different alloys and metals.
However, operatives should be aware that the technique should not be carried out without proper training. MIG welding equipments complicated to install, and both a constant flow of gas and a source of direct current are required to operate it. In practice, the technique is also fundamentally different to traditional welding global deicer troubleshooting processes, which means that even welding veterans will need to extensive retraining before they can competently operate MIG welding equipment.Because of the need for an inert gas shield, MIG welding equipment must also be installed in a secure environment, as an air current will interfere with the shielding process.
Despite these restrictions, MIG welding remains an extremely popular welding technique, and is now commonly used in a variety of manufacturing operations. Due to the speed and precision of the process,MIG weldinghas become particularly popular in the automobile industry, but it is also used in a wide range of smaller metalworking operations as well. If you would like to know more about obtaining MIG welding supplies, contact a specialist retailer like , who will be able to help you find the right equipment for your business needs.…

Storage With Tilt Bins

master5 years ago03 mins

A day care center has lots and lots of supplies to cater to every child’s needs and help his/her develop all the skills necessary to grow into a mature, responsible, independent, responsive, caring, etc individual. Art equipment, toys, books and play things are among the necessary materials that help to stimulate the children’s imagination, develop and enhance their talents and skills and improve their academic performance.
If the day care center does not watch out, all these materials will crowd the center itself very soon. Or, the teacher could end up picking them one by one and return them to their proper storage. Storage space is an important part of the day care center or the playroom (if there is a separate space for this since some centers have classrooms doubling up as playrooms). Since children use different materials during the course of their various activities, it is not far fetched to imagine that at the end of the day, all these things are brought down and likely scattered across the room. To avoid tis is to have available a storage space.
Today, a new form of storage has come out of the market. And this is the tilt bin. Literally, tilt bins tilt making it easy for children to throw in there their materials after use. Tilt bins are made sturdy, built with multi-coloured bins that can be locked demand increases and supply increases tightly to avoid any item from dropping, have round edges instead of sharp ones for safety and come with transparent covers, which make it easy for children to see and identify the items inside and so know where to place each one of their playthings.
With tilt bins, children are taught to be organized as they keep things where they should be and learn to be independent by way of retrieving complete tig welding kit and returning items no longer needed where they belong on their own and, in the process, learn to be responsible at a young age.…

Boat Safety Equipment: Personal Flotation Devices

master5 years ago05 mins

When thinking about boat safety equipment, the first item you probably purchase is the personal flotation device, also known as the PFD. The PFD is designed to give you buoyancy in the case of an introduction of demand for project emergency. However, when looking to purchase this piece of boat safety equipment, you might be surprised to learn there are several types to choose from and you need to know the differences.
First and foremost, know that most states require you by law to wear a PFD that has been approved by the United States Coast Guard. The device must be in good condition, properly fit the intended user, and be readily accessible. There are five types and we’ll go through the differences between each kind.
Type I: Offshore Life Jackets. These jackets are intended for use in open, rough or remote waters where it may take longer for rescue. They offer the most buoyancy and turn most unconscious people upright. It is also the most bulky of the jackets.
Type II: Near Shore Vests. This vest is intended for calmer inland waters where rescue will not take long at all. They will turn some unconscious users face up, but not all. They are less bulky than a Type I, but still relatively large.
Type III: Flotation Aids. They are the most comfortable to wear and are good for water sports and other activities. They are excellent for continuous wear and allow a good amount of movement. The flotation aids should be used where rescue will be quick. They will not turn an unconscious person face up.
Type IV: Throwable Devices. These are cushions or rings thrown to people in distress. They are actually a supplement to your life jacket. They should not be used in rough water, for non-swimmers, or people who are unconscious.
Type V: Special Use Devices. Like the name suggests, these devices are specially made for specific activities, such as kayaking, waterskiing, or windsurfing.
For adults, they need to look at their chest size, and not their weight, to determine what size jacket or vest to purchase. Sizing varies by brand, so always look at the sizing charts for that specific brand. A PFD should fit snugly, but still allow you to move freely without chaffing. Women might want to consider purchasing this boat safety equipment catered to them over a unisex jacket. For kids, it’s vital you get the right size. Do not purchase a larger PFD thinking they will grow into it. This is dangerous for their safety. Children’s sizing will depend on weight and not chest size.
A PFD is one type of boat safety gear you cannot afford to get wrong. Choose top quality brands and purchase the characteristics of a good product manager right device for your activity. The most important piece advice I can give you is to actually wear the PFD!…

7 Protective Items To Use With Your Chainsaw

master5 years ago06 mins

Many people wrongly feel that protective equipment is just something that novices use. The more experienced users of chainsaws do not need them. This is totally false. Even professional loggers use protective equipment, and do so because of one reason only. It safeguards them from injuries.
Of course this does not mean that you go swathed from head to toe whenever you want to use your chainsaw, but rudimentary precautions are essential.
Safety hat – This is so that you don’t get a knock on your own head. There can be a number of reasons why you may be in danger of falling objects, and if you are to concentrate solely on your cutting, you need to be sure that your head is safe. A hard hat will ensure this.
Gloves – They are not only for style. Your hands are the part of your body that is nearest to the chainsaw which means that they are the most in danger of getting injured by splinters. Even though most manufacturers say that the they have designed their chainsaws to minimize this from happening, there is no way that they can prevent it entirely. Having gloves will ensure that your hands are protected.
Plus your gloves will help you get a good grip on your chainsaw. When you are using it for some time, your palms will sweat, with the product development cycle product manager risk of you not being able to hold on to the saw properly. The gloves will negate any problems that arise out of sweaty palms.
Protective eyewear – This is most important because your eyes are the single most precious organ in the body, and a stray splinter can injure your eye to such an extent that it can cause permanent damage. Simple, all enveloping goggles are available that will do a good job of keeping these chips away from your eyes.
Boots – Don’t use your chainsaw unless you have good boots that give you a firm footing. Sneakers are good as long as you are running along the ground, but are really not meant to be steel action plan european commission used when you do this kind of work. You need something that has hard, knobbly soles that will grip the ground properly so that you don’t slip and fall while operating the chainsaw.
Earmuffs – Unless you want to get hard of hearing earmuffs are a good idea as it will protect your ears from damage.
Apart from these there are other optional pieces of equipment that you can wear.
Vest – The vest will protect you from flying splinters to the body. While many people may feel that they don’t need one, the long and short of it is that it does protect you. Wearing one, especially with full sleeves will ensure that your arms, the portion that is not covered by the gloves too are protected. You could of course also use a leather jacket if you have one lying around.…

HSE Reports 4312 Deaths Due To Asbestos Related Diseases

That’s right, the HSE has reported that there were around 4312 deaths due to asbestos related diseases in 2007 (the latest year with published statistics).A� Do you work in the building trade?A� Do you wear the correct PPE when dealing with asbestos? or do you think that health and safety is not worth the time of day?A� If you don’t wear PPE and think that health and safety is not important, then it’s about time that you woke up and learnt about the risks involved when dealing with asbestos, and the affects that it can have on you later in life.A� It isA�no joke,A� asbestos really isA�a hidden killer, and it will get you when your not expecting it.

What is Asbestos?

Asbestos is commonly known as the hidden killer, due to the fact that you can’t see it, and because it does not usually cause any symptoms for many years after exposure.A� Asbestos almost always causes death.

Asbestos is a term used for a wide range of naturally occurring minerals that crystallise to form long thin fibres and fibre bundles.A� Asbestos fibres have high tensile strength, chemical, electrical and heat resistance.A� For this reason, asbestos was used in nearly all UK buildings built before the year 2000, and it was and still is used in many other countries around the globe.

Asbestos is a hazardous material, and can pose great risks to health if the fibres are disturbed, let looseA�in the air, andA�thenA�inhaled.

History

Asbestos became a popular product to builders and manufacturers in the early 1900’s.A� Builders and manufacturers used to love using asbestos because of its great durability.A� Asbestos is fire retardant, and it was commonly used for insulations.

It is estimated that 3,000 different types of products contain asbestos.A� The global first aid kit use of asbestos ranges from paper products, brake linnings and floor tiles.

Who is at risk of being exposed?

If asbestos is left intact and undisturbed, it does not cause a health risk.A� Asbestos only causes health risk if it is tampered with, and if the person tampering with it is not wearing a face mask and protective clothing.

Many cases of these diseases occurring now are a result of exposure in industries that used asbestos in the past.A� A majority of these new casesA�have mainly affected people working in building and maintenance trades.A�

People mostly affected with asbestos related diseases include, Carpenters, Plumbers, Electricians, Labourers, Metal Plate Workers, Pipe Fitters, Construction Operatives, Construction Managers and Energy Plant Operatives.

What diseases are caused by asbestos?

Mesothelioma – Mesothelioma is a cancer exclusively related to asbestos.A� It is almost always fatal to those who are affected.A� People who are diagnosed with mesothelioma usually die within 1 or 2 years of diagnoses.A� It has a long tendency period, and it does not start to affect the body or cause symptoms for typically 30-40 years.

Lung Cancer – Asbestos related lung cancer typically takes at least …
