Established in 1993, NMTS is dedicated to serving every aspect of your contract quality inspection needs through experience and integrity. We help contractors around the nation fill much-needed temporary positions for certified welding inspectors. 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. . 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. . 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. Plasma Arc Welding. Solid State Welding . Radiant Energy Welding Process . Radiant Energy Beam focuses an energy beam on the work-piece. The heat is generated only when the energy . beam . strikes the work-piece. Radiant Energy beam includes . 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 . 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. . 29 CFR 1926 . – . Subpart . J. Presented by. : . ETTA. . Bureau, 919-807-2875. Objectives. In this course, we will discuss the following:. OSHA’s minimum requirements for:. Gas welding and cutting. ASTE 3030. Objectives. Define working drawing, print, orthographic projection, and mechanical drawing. Create a working drawing of your project. Differentiate and use different types of lines used on a drawing. AKA “Arc Welding. Officially known as: SMAW – “Shielded Metal Arc Welding . “Stick Welding”, AKA “Arc Welding. Officially known as: SMAW – “Shielded Metal Arc Welding . “Stick Welding”, AKA “Arc Welding. OBJECTIVES. After completing this chapter, the student should be able to. understand the basics of joint design.. list the five major types of joints.. list seven types of weld grooves.. identify the major parts of a welding symbol.. 9.1 Joints and their classifications. Joint. :. any point where two bones meet; both movable and immovable. Arthrology. : science of joint structure, function and dysfunction. Kinesiology. : study of musculoskeletal movement.
