Influence of Cooling Mode on the Electrode Caps from Alloy Cu-Cr-Zr Operating Life at Resistance Spot Welding.

Original language description

For production bearing welds at resistance spot welding there is very important value about number of welds made by electrodes at which is created regular welding spot higher than certain minimal value and thus also efficient bearing capacity. During welding there is with increasing number of welded spots simultaneously also wearing of electrode working area, changing of conditions for creation weld joints and thus also their quality. In consequence of electrical, mechanical, thermal and metallurgical loading there are changes in electrode working area geometry, changes in roughness and fouling of working areas, changes of mechanical and physical properties of electrode material. There is very important influence of the electrode working area surface temperature on the operating life. Within the scope of this paper there is description of new female electrode caps cooling system by liquid carbon dioxide. There is evaluated influence of cooling on the female electrode caps temperature course in the zone of its working area. On the basis of metallographic evaluation there is examining influence of electrode cap cooling mode on the change of its working area geometry and thermal affection. Upon the base of results from mechanical tests there is evaluated decrease of dimension and bearing capacity with increasing number of welded spots.
