Orbital welding is a welding technique that is used to weld pipes or tubes. Its first use was found in the 1960s when the aerospace industry recognized the need for a superior joining technique for aircraft hydraulic lines. It was initially used to be done manually. But with advancements in technology, the welders start using …
Submerged Arc Welding (SAW) is one of the welding processes used in the welding industry. In the industries where long welds and thick steel sheets are involved, submerged arc welding is employed. It is a high-yield automated welding process. The SAW process is normally operated in semi-automatic or automatic mode. Also, it is limited to …
Electron Beam Welding is a fusion welding process. It uses the kinetic energy of highly accelerated electrons emitted by the cathode tube or electron gun. When the highly accelerated electrons are bombarded on the workpiece, their kinetic energy is converted into thermal energy. The process is performed in vacuum conditions for preventing electron beam dissipation. …
Atomic Hydrogen Welding or Atomic Hydrogen Arc Welding is a welding technique that uses an arc between two tungsten electrodes in the presence of hydrogen gas. The electric arc formed between the two electrodes breaks the hydrogen molecules, which later react together to recombine. As a result, the process of recombination releases a high amount …
Plasma Arc Welding or PAW is an arc gas welding process similar to Gas Tungsten Arc Welding (GTAW). More candidly, PAW is a gas-shielded process using a constricted arc between the metal piece and the non-consumable tungsten electrode. The difference between GTAW and PAW is in the way of setting electrodes in the nose of …
