Welding — is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld puddle ) that cools to… … Wikipedia
Welding defect — A welding defect is any flaw that compromises the usefulness of the finished weldment. According to the American Society of Mechanical Engineers (ASME) welding defect causes are broken down into the following percentages: 41% poor process… … Wikipedia
Welding Procedure Specification — A Welding Procedure Specification (WPS) is a formal document describing welding procedures. According to the American Welding Society (AWS), a WPS provides in detail the required welding variables for specific application to assure repeatability… … Wikipedia
Welding software — is a general term for welding related software, i.e. applications addressing variety of topics associated with the welding industry, including base metal selection software, filler metal selection, machine welding settings/instructions, weld… … Wikipedia
welding — Technique for joining metallic parts, usually through the application of heat. Discovered in the 1st millennium AD during attempts to manipulate iron into useful shapes, the technique produced a strong, tough blade. Welding traditionally involved … Universalium

Arc welding — uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non consumable electrodes.… … Wikipedia
Flux-cored arc welding — (FCAW) is a semi automatic or automatic arc welding process. FCAW requires a continuously fed consumable tubular electrode containing a flux and a constant voltage or, less commonly, a constant electric current welding power supply. An externally … Wikipedia
Plasma arc welding — (PAW) is an arc welding process similar to gas tungsten arc welding (GTAW). The electric arc is formed between an electrode (which is usually but not always made of sintered tungsten) and the workpiece. The key difference from GTAW is that in PAW … Wikipedia
