Abstract
Given are the results of investigations into capacitor-discharge welding of studs of aluminium-magnesium alloy AMg3 and stainless steel 10Kh18N9T under conditions of medium and high vacuum. It is shown that a high-current short-time pulsed discharge, at which the major part of evaporated metal remains in the gap between the mating surfaces, can be used for vacuum butt welding of compact-section parts to a sheet material. It is experimentally proved that up to M6 diameter studs can be welded at pressure of 1.33 Pa with a static tensile strength value of the joints being equal to that of the stud material.
