"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. " - Shunting in spot welding

WebJun 1, 2024 · Also, insufficient spot spacing causes the second spot to be weaker than the first due to current shunting. Another critical design specification: center-to-center spot-weld spacing. Since electricity always takes the path of least resistance, a second spot weld made too closely to the first will be weak, because part of the weld current shunts through … WebDescription. Since shunting always reduces the actual welding current, it should be avoided whenever possible. There are two primary sources of shunting: (1) Shunting due to existing spot welds, as shown in Fig. 1. (2) Shunting due to design, as shown in Fig. 2, where shunting inevitably occurs in series welding process.
