welding metal
41explosive welding — welding by means of a controlled explosion that rapidly forces two pieces of metal together …
42sheet metal — Metal that has been flattened or rolled, and can then be cut, bent, joined, and otherwise formed, and perhaps coated or patinated. See the names of various metals, charts of steel sheet gauges, jewelry, sculpture, the names of various… …
43Shielded metal arc welding — (SMAW), also known as manual metal arc (MMA) welding, flux shielded arc welding …
44Arc 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.… …
45Spot welding — is a type of resistance welding used to weld various sheet metal products. Typically the sheets are in the 0.5 3.0 mm thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to… …
46Electric 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… …
47Fabrication (metal) — Fabricator redirects here. For other uses, see Fabricator (disambiguation). A typical steel fabrication shop …
48Resistance welding — refers to a group of welding processes that produce coalescence of faying surfaces where heat to form the weld is generated by the resistance of the welding current through the workpieces. Some factors influencing heat or welding temperatures are …
49Flux-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 …
50Friction 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 …
