Abstract :
Conditions of obtaining high quality welded joints by micro resistance welding are analyzed. Construction principle of the former of special form current pulses for micro resistance welding is offered. The former provides forming of weld current power pulse in accordance with electrophysic processes in welding contact. Offered pulse former included in experimental welding machine is used for welding details of important application. The results of experiments are given.
