Shunting spot welding
WebShunting effect occurs in RSW when the electrical current passes through previous spot welds. Value of this current depends mostly on distance, number, and size of previous spot welds. This will cause some dimensional and metallurgical changes in welding nugget as well as heat affected zone (HAZ). In this study, shunting effect of RSW is considered in a … Webseveral spot welds are made close to each other. In such cases, previously made welds may affect the new weld and part of the current aimed for the new weld passes through the neighbouring welds. This effect is called shunting and is known to affect weld quality and reduce weld strength. A schematic of shunting is shown in Figure 1.

WebThe E-Coat on the mating surfaces can be saved when using STRSW with the use of the Dent Fix Shunting Pliers (DF-SP360). Simply remove the coating from only the outside surfaces, position the shunting clamp at the spot weld site, and the spot weld is made at the adjacent site. The current chooses the path of least resistance when confronting ...
