Jump Liner U SA Made with Pride and withou Compromise in th Jump Liners replace only the most commonly to reduce the amount of time a gun is offline and minimize inventoryso gun from Available i. Welding. Welding processes are conveniently divided into two classes: . fusion welding and solid state welding. . . During fusion welding a portion of the base materials to be joined is melted and mixed, often with the addition of a filler metal, forming a solid joint after subsequent solidification. . SOURCE. www.agednet.com. AE240 Arc Welding Safety. Heat for arc welding is obtained by electricity. Electric current flows from a transformer connected to lines from a power plant. Other sources for electricity for welding are electric motors and gas engines driving special generators. . Objectives. In this course, we will discuss the following:. OSHA’s minimum requirements for:. Gas welding and cutting. Arc welding and cutting. Fire prevention. Ventilation and protection. Safe use, handling, and precautions to take when welding and cutting. A Brief History of Welding. Late 19. th. Century. Scientists/engineers apply advances in electricity to heat and/or join metals (Le Chatelier, Joule, etc.). Early 20. th. Century. Prior to WWI welding was not trusted as a method to join two metals due to crack issues. Welding Metallurgy. Study of Welding Metallurgy is important because the overall-mechanical properties of a . weldments . are . determined . by the properties of individual microstructure present in the weld deposit and the weld heat . T-joint. T-joint welded using arc welding. T-joint welded using . tig. T-joint welded using . mig. Lap joint. Lap joint welded using . tig. Lap joint welded using arc welding. Lap joint welded using . Duties . Welders join or sever metals in beams, girders, vessels, piping and other metal components, make metal parts used in construction and manufacturing plants, and weld parts, tools, machines and equipment.. Covered in Subpart H, but an integral part of welding, cutting and brazing. Compressed gases-hazards. compressed energy. flammable, asphyxiants, oxidizers. Gases are used for cutting, brazing and “shielding” the weld. A Brief History of Welding. Late 19. th. Century.
