Shunting Effect in Resistance Spot Welded Joints of Aluminum …

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 … WebShunting effect of resistance spot welding is evaluated based on the electrode displacement signals. The shunted welds in mild steel with different weld spacing were produced. The results showed that the weld spacing and nugget diameter were polynomial-correlated, and the minimum welding spacing of 20 mm can be derived from the results. WebShunting paths that can occur typically happen after the monitoring devices.

WebShunting is the loss of electrical current via the secondary circuit provided due to existence of previous nugget in a series of spot welds.***T. J. SNOW spe... WebYes, there is a minimum spacing for spot welds listed in most sample weld schedules. If welds are placed too close together, the weld current can flow through/across the sheet of metal between the desired weld and previous weld locations as shown. This current does not flow through the desired weld joint and therefore does not help create a nugget.
