  • 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 joints — are formed by welding two or more workpieces, made of metals or plastics, according to a particular geometry. The most common types are butt and lap joints; there are various lesser used welding joints including flange and corner joints. Contents …   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 power supply — A welding power supply is a device that provides an electric current to perform welding. Welding usually requires high current (over 80 amperes) and it can need above 12,000 amps in spot welding. Low current can also be used; welding two razor… …   Wikipedia

  • 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

  • Gas tungsten arc welding — TIG welding of a bronze sculpture Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG …   Wikipedia

  • Oxy-fuel welding and cutting — Oxyacetylene redirects here. For the song, see Cubanate. Side of metal, cut by oxygen propane cutting torch …   Wikipedia

  • Gas metal arc welding — RMD redirects here. RMD may also refer to IRA Required Minimum Distributions. Gas metal arc welding …   Wikipedia

  • Friction stir welding — (FSW) is a solid state joining process (meaning the metal is not melted during the process) and is used for applications where the original metal characteristics must remain unchanged as far as possible. This process is primarily used on aluminum …   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

  • Electric resistance welding — (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescence of faying surfaces where heat to form the weld is generated by the electical reistance of material vs the time and the force used to hold the… …   Wikipedia
