Finally,the process of electric resistance welding is carried out by passing a high-frequency electric current through sliding contacts on the pipe surface,fusing the edges together to create a neat defect-free weld.This type of pipe is generally available in smaller diameter sizes ofEffect of a slightly concave electrode on resistance spot Oct 31,2020Research on micro-electric resistance slip welding of Electric resistance welding at a glance#0183;Electrical resistance welding (ERW) is a form of pressure welding which utilizes heat generated by electrical resistance of the material along with applied force to hold the pieces together during the welding process.There are different types of ERW processes and all produce a forged weld.ERW Steel Pipes Electric resistance welding at a glanceSeveral electric resistance welding (ERW) processes are available for tube and pipe production.While each process has different characteristics,all ERW processes have one thing in commonall of them produce a forged weld.A forged weld is created by applying a combination of heat and pressure,or forging force,to the weld zone.

Arc Welding vs.Spot Welding Whats the Difference

Spot welding uses electric resistance current flow to join pieces with no filler.Put another way,arc welding is like lightning,while spot welding is like an electric hot plate.The different ways of heating metal give each process strengths and weaknesses that are suited to different situations.Lets look more deeply at each
