Weld Mechanical and Electrical Properties

weld strength versus resistance

Is there a relationship netween weld mechanical and electrical properties? The basic conclusion is that low electrical resistances were found to correlate with high mechanical strengths of the welds. Correlation between electrical resistance and tensile strength for welds produced with (blue markers) and without (red markers) spatial beam oscillation. [1] This post has been built … Read more

Electrical Contact Resistance

The Electrical Contact Resistance at a metal to metal contact is primarily governed by: The surface structure can be further described by the surface flatness, surface oxidation and water adsorption. These joints in a battery pack will either be welded or bolted. Initially the easiest to think about is the bolted busbar joint. The bolt … Read more
