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. . 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.. About Us. Plastic Welding and Fabrication, Ltd (PWF) . started in 2003. . L. ike . most other small . businesses PWF started . working out . of a . garage. We have since moved twice . and currently has two buildings in Buda, TX.. 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 . 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.. Joining and Assembly. Joining . - . welding. , . brazing. , . soldering. , and adhesive bonding. These processes form a permanent joint between parts. Assembly - mechanical methods (usually) of fastening parts together. 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. Hot Work. . . . Bureau of Workers’ Comp. PA Training for Health & Safety. (PATHS). OSHA 29CFR1910.251-255 . 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..
