Welding-spicing method for limiting reverse multiple workpieces on most outer surface involves heating bond material over lowest temperature for coordinating to form joint

摘要

The welding-spicing method involves placing each protrusion piece and at least one layer in the middle and locating them between closing workpieces for coordinating each protrusion piece with closing workpieces for limiting at least one initial joint axial line; using a resistance welding device to join with the surface reversely along at least one axial line so as to deform and melt the protrusion piece; and heating the bond material over the lowest temperature for coordinating to form the joint. An independent claim is also included for a manufacturing piece used in the welding-splicing procedure.
