Shunting effect in spot welding
WebFeb 1, 2024 · Shunting effect of resistance spot welding is evaluated based on the electrode displacement signals. The shunted welds in mild steel with different weld spacing were … WebDec 25, 2015 · The existing welds may divert the electric current intended for the new weld, a phenomenon called shunting. As the ap- plied electric current is shared by the weld to be made (the shunted weld) and the ex- isting weld (the shunt weld), the heat gen- erated in the shunted weld may not be suf- ficient for it to grow to the designated size.

Aslanlaret. al.[1] explored the impacts of welding time on the malleable peel quality and ductile shear quality. of resistance spot welding joints of chromate miniaturized scale alloyed steel sheets. Elastic peel quality and malleable shear quality was investigated by utilizing related period charts as a part of request to get ideal weld times. WebThe primary reason why oxyacetylene and stick-arc welding are no longer recommended for collision repair is that: there is too much heat-affect. Technician A says that when making a spot weld, the current is usually on for 2–3 seconds. Technician B says that when making a spot weld, the electrode arms release immediately after the current ...
WebDissimilar Metal Welding Shunting Effect Previously made welds may affect the subsequent welding if the welds are spaced close to each other due to electric current shunting. The welding current may be diverted from the intended path by the previously made welds. As a result, the current or current density may not be sufficient to produce a ...
