FIELD: process engineering.;SUBSTANCE: invention may be used at automatic transfer lines for contact point welding of car body elements. Proposed device consists of case 1 with supports 2, built-in transformer 3 and moving carriage 4. The latter supports electric holder 10 with moving and fixed...
The crosscut socket is accomplished with the crosscut slot that is open towards the stem secondary longitudinal channel.;EFFECT: socket and electrode cooling raise by virtue of ended socket walls multisided cooling, the electrode durability increases at the very least 1,5 times.;1 dwg...
The new resistance testing method uses the Medar weld controller to pass a significantly higher current than that used in the existing method. Several tests were conducted to evaluate the effect of the higher test current on pinch welds and to evaluate the proposed test methods capabilities to ...
