The joint with the thin fusion layer at the interface is accomplished by means of using the pulsed high current. The factors related to the joining mechanism are described and these factors may be chiefly related to the exothermic phenomenon as follows. The evolution of heat at the interface is found to be connected with heating of resistance caused by the actual constricted contact between two metal surfaces. The electrode force keeps the important role for the enlargement of this constricted contact setting the current path due to the generation of heat through the weld time. Using the electrode force changing up a certain slope, the joint with good mechanical properties is found to be obtained by the energy input smaller than using the constant electrode force.
