PPT-Arc Welder Power Supply Converts AC power to welding current. SMAW and GTAW processes

GMAW Welder A constant voltage power supply with a wire electrode feed May be used with solid or flux core wire Commonly used with a shielding gas required for solid wire electrode Common shielding gasses are carbon dioxcide and argon. 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. . INTRODUCTION. ELECTRIC ARC WELDING. The welding in which the electric arc is produced to give heat for the purpose of joining two . surfaces is . called electric arc welding. Principle. Power supply is given to electrode and the work. A suitable gap is kept between the work . 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. . 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. 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 . Presentation by:. N.SHASHANK REDDY-BT14EEE058. NAITIK ATUL SHAH-BT14EEE059. N.HARSHITHA-BT14EEE060.
