Welding is a process for permanently joining two or more pieces of metal to make a single piece. It is an important industrial process, and has a huge impact on the economy of the United States. In fact, almost all of the things we use everyday has either been welded or had been manufactured by equipment that had been welded. These include kitchen utensils, automobiles, buildings, bridges and other infrastructure.
Welding is done through application of heat or compression or both. Usually, heat is applied using an arc flame. This type of welding is called arc welding. Some people have this confused with soldering, which is a slightly industrial supplies examples different process. In soldering, another material is melted in between the parts that are to be fused. Arc welding, on the other hand, uses the heat from the arc to actually melt the pieces of metal together.
Welding may also use a filler metal that is melted into the seam of the fused pieces. This is done either through a manual wire feeder in the welding rod, or a welding gun equipped with a wire feeder.
In preparation for the welding, the edges of the pieces to be welded are shaped into a groove, usually a V-shaped groove. The arc flame creates a molten pool from the grooved edge of the metal pieces and the filler metal. A shielding gas from the welding torch surrounds the molten pool. The shielding gas is necessary to prevent oxygenation and weakening of the welded pieces.
Commonly welded metals include aluminum and steel. Plastics are also classification of milling machine welded, but the heat source used is hot air or an electric resistor.
Different industry groups hire different types of welders. In the construction industry, welders work on building of bridges and subways. Machinery manufacturers employ welders for making cranes and bulldozers, food-processing equipment, printing machinery, and other heavy equipment. The transportation industry hire welders for manufacturing land and water-based vehicles, as well as aircraft.
Welders also perform maintenance and repair work for automobile body shops and shops that specialize on repairing industrial machinery. Welders are present in the petroleum industry, especially in the construction of oilrigs. In the electric industry, welders are needed in the building of electric generators and appliances.
Training of professional welders usually requires knowledge of industrial math, measurements and workplace safety regulations. Technical skills focus on the identification of electrode colors, selection of the correct tip for gas welding, understanding of welding prints, and a working knowledge of the different applications of gas tungsten arc welding and gas metal arc welding. Welders also need to be familiar with the different shielding gases and filler metals used in welding. They are given training on proper procedures for inspecting and testing of welds. Welding training always go hand-in-hand with apprenticeship and on-the-job training, as the best way to acquire the necessary knowledge in this field is through direct application of skills learned.

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 …

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.

Welding goggles are made to protect the wearer from facial and eye injury caused by flying shrapnel, heat or harmful radiation. It is necessary that this protective device is cared for and maintained according to the manufacturer’s guidelines. It is also important to carefully inspect them on a regular basis for scratches, cracks and other defects and to test their comfort when worn. Defective goggles will reduce the efficiency of the goggles and might not only lead to a poor weld but could potentially be a source of grave injury to the welder.
The choice of material used in the manufacture of the goggles will determine what kind of maintenance they would require. Goggles made of anti scratch (hard coated) lenses are less liable to scratch.
In caring for welding goggles, a few basic procedures need to be observed. For instance cleaning the welding goggles should be done on a daily basis to rid it of slag and dust. Cleaning can be done using a clean cloth or as specified by the manufacturer. Dirty lenses will impair vision and lead to errors in the weld.
Lenses that are scratched weaken the shade power of the goggles and lead to exposure to dangerous ultraviolet rays, infrared and bright lights. They reduce the classification of milling machine vision of the wearer, which can also lead to a weak weld. Therefore it is important that welding safety goggles are handled with care to prevent scratching.
The storage of welding safety goggles constitute an important element in caring for your goggles. How they are stored will go a long way in determining their lifespan. Safety goggles should be stored in a dry, clean place and should be kept in a soft case when they are not in use so that even if they should fall, they will be in their protective case and kept safe from damage. Poor storage of the welding goggles will lead to scratches on the lens surface and a weakening of the shade power of the lens.
If for some reason, the welding safety goggle should get damaged, the damaged part should promptly be replaced with an original and identical part from the manufacturer. Failure to replace damaged parts impairs the efficiency and reduces the safety element of the goggle, resulting in potential eye damage for the wearer.
From time to time, goggles should be disinfected using a general disinfectant. On the other hand, they could marx capital chapter 15 summary either be placed at 100 degrees C for about an hour or in an ultraviolet light germicide chamber.
According to OSHA (Occupational Safety and Health Administration) 29CFR1910.133, it is the duty of the employer to clean, disinfect and store safety goggles.
