A Welding Procedure Specification (WPS) is a formal document describing welding procedures. It is an internal document used by welding companies to instruct welders (or welding operators) on how to achieve quality production welds that meet all relevant code requirements. Each company typically develops their own WPS for each material alloy and ...
Induction welding: 74: IW Laser beam welding: 521 522: LBW Deep penetration, fast, high equipment cost Automotive industry Laser-hybrid welding: Combines LBW with GMAW in the same welding head, able to bridge gaps up to 2mm (between plates), previously not possible with LBW alone. Automotive, Shipbuilding, Steelwork industries Percussion ...
The basic welding symbol which goes on the reference line to indicate the shape of the weld such as a fillet or plug. The symbol is placed on the arrow side or other side of the line to indicate which side of the joint the weld goes. The dimensions and other numbers such as the length of the weld or number of spot welds go above and below the ...

Welding. Overhead stick welding. Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion. Common alternative methods include solvent welding (of thermoplastics) using chemicals to melt materials being bonded ...
Welder certification is based on specially designed tests to determine a welder 's skill and ability to deposit sound weld metal. The main part of the welder's test consists of welding one or more test coupons which are then examined using non-destructive and destructive methods. The extent of certification is described by a number of variables ...
Magnetic pulse welding (MPW) is a solid state welding process that uses magnetic forces to weld two workpieces together. The welding mechanism is most similar to that of explosion welding . [1] Magnetic pulse welding started [ clarification needed ] in the early 1970s, when the automotive industry began to use solid state welding.
A welding power supply is a device that provides or modulates an electric current to perform arc welding. [ 1] There are multiple arc welding processes ranging from Shielded Metal Arc Welding (SMAW) to inert shielding gas like Gas metal arc welding (GMAW) or Gas tungsten arc welding (GTAW). Welding power supplies primarily serve as devices that ...
