Electric resistance welding - Wikipedia
Electric resistance welding (ERW) refers to a group of welding process in which parts to be welded are first heated to the fusion temperature by the resistance of work piece to the flow of electric current and then squeeze by mechanical pressure to accomplish weld. No filler metal or flux is added in this process. Spot welding is a resistance welding method used to join two or more
Pipe (fluid conveyance) - Wikipedia
A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit ERW pipes are manufactured from the longitudinal welding of steel.
