Welding is a process for permanently joining two or more pieces of metal to make a single piece. It is a vital industrial process, and has a big impact on the economy of the United States. Actually, almost all the things we use everyday has either been welded or had been manufactured by atlantic petroleum equipment inc jp equipment that had been welded. These include kitchen utensils, automobiles, buildings, bridges and other infrastructure.
Welding is finished through application of heat or compression or both. Usually, heat is applied using an arc flame. This kind of welding known as arc welding. Some people have this confused with soldering, which is a slightly different process. In soldering, another material is melted in between the parts which might be to be fused. Arc welding, on the other hand, uses the heat from the arc to truly 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 completed atlantic petroleum equipment inc jp either through a manual wire feeder within 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 right 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 critical to forestall oxygenation and weakening of the welded pieces.
Commonly welded metals include aluminum and steel. Plastics are also welded, but the heat source used is hot air or an electric resistor.
Different industry groups hire various kinds of welders. In the development 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, in addition to 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. Within 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 concentrate on the identification of electrode colors, selection of the proper 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 should be conversant in the different shielding gases and filler metals utilized in welding. They’re 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 one of the simplest ways to amass the required knowledge on this field is through direct application of skills learned. In case you are concerned atlantic petroleum equipment inc jp with becoming an expert welder, and are looking for an acceptable training school, look for one that is aligned with the standards of the Bureau of Apprenticeship and Training.
