The welding process passes a very large current, AC or DC, through the junction of two pieces of metal being joined so that the DC resistance in between the two electrodes gets hot enough to melt some ...

Without a full understanding of the importance of these variables and their relation to one another, weak and/or ugly weld joints can result. Unfortunately, the spot-welding process often gets the ...

Steel/aluminum subframes built with the new technique are said to be 25 percent lighter than those made entirely out of steel, which should translate into improved fuel economy. The process also ...

Currently, the resistance spot welding process is already in place on the Cadillac CTS-V as well as the liftgates of the Hybrid variants of the Chevy Tahoe and GMC Yukon, but GM has plans to ...

The resistance spot welding involves electric, thermal and mechanical phenomenon. In this paper, the aspects of process analysis and modeling are discussed. The mechanical properties, electrical ...
