PPT-Welding and Hot Work What is Hot Work?

Hot work is any work process that produces flames or sparks that present a fire ignition hazard to the surrounding environment and personnel Gas torch welding and cutting uses a flame to join or cut metal. 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. . INTRODUCTION. ELECTRIC ARC WELDING. The welding in which the electric arc is produced to give heat for the purpose of joining two . surfaces is . called electric arc welding. Principle. Power supply is given to electrode and the work. A suitable gap is kept between the work . 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. 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. 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 . Definitions. Weld. A localized fusion of metals produced by heating to suitable temperatures. . Pressure and/or filler metal may or may not be used. . The filler material has a melting point . approximately . 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..
