CHAPTER 12 Flux Cored Arc Welding Equipment Setup and Operation OBJECTIVES After completing this chapter the student should be able to explain the FCA welding process describe what equipment is needed for FCA welding. 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.. WELDING:. Process of joining similar metals with the application of heat and with or without the application of pressure.. While welding the edges of metal pieces are either melted or brought into plastic condition.. 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. T-joint. T-joint welded using arc welding. T-joint welded using . tig. T-joint welded using . mig. Lap joint.
