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. 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. 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.. 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 . 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 . Tig and Mig welding. By: Luke Woroniecki. Table of Contents. Welding Certification and Qualification. Codes.
