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.  . Robot Welding . is a process of joining different materials. . The . large bulk of materials that are welded are metals and their alloys although welding is also applied to the joining of other materials such as thermoplastics. 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. 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 . 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 . 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. ASTE 3030. Objectives. Define working drawing, print, orthographic projection, and mechanical drawing.
