Flash welding
Encyclopedia
Flash welding is a type of resistance welding
that involves pressing two ends together, while simultaneously running a current
between them. This has the effect of forming a joint between the two metals that is free of oxide
s as the surfaces of the two joining parts is forced out the sides of the joint and is known as flash, hence the name.
Resistance welding
Electric resistance welding 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 materials together during welding...

Electric current
Electric current is a flow of electric charge through a medium.This charge is typically carried by moving electrons in a conductor such as wire...
