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. . History of Welding. Welding was used in the construction of the iron pillar in Delhi India, erected about 310 AD and weighing 5.4 metric tons. . History of welding. Welding, was transformed during the 19th century. In 1802, Russian scientist Vasily Petrov discovered the electric arc and subsequently proposed its possible practical applications, including welding.. Stanley High school shop. Safety Hazards in the Welding Shop include:. . - Flames, sparks, slag, harmful rays, fumes, and fire hazards. . - Always wear proper PPE in order to minimize risk . . of being affected by these hazards. . 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 . Background. Thermosetting and thermoplastic polymers are two kinds . of matrix . for . fibre reinforced polymer (FRP) . composites. Compared with thermosetting . composites (TSC), thermoplastic composites (TPC) are . Tig and Mig welding. By: Luke Woroniecki. Table of Contents. Welding Certification and Qualification. Codes.
