Shunting effect in 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 … WebJun 13, 2016 · Shunting effect is the loss of electrical current via the secondary circuit provided due to the existence of previous nugget in a series of welding spots.

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. http://siampart.com/content/file/tips/0915161473907419.pdf
