Resistance Welding Process
Spot welding-Assembly-welding lap joints, and pressed between two cylindrical electrodes, using resistance heat melts the base metal, forming the solder.
Seam welding--a rotating disc-shaped roller electrode welding Assembly into lap or butt joints, and placed the rollers between the electrodes, wheel pressure welding and rotation, continuous or discontinuous transmission, forming a continuous weld.
Welding – welding weld along the entire contact surface.
Projection welding – a workpiece (metal) surface preparation of fit out one or more processes, so that its contact with another surface and ohmic heating, and then collapsed, forming the solder is added to these contacts.
