WebShunting paths that can occur typically happen after the monitoring devices. For example, as the welding gun is clamping the work piece, other parts of the gun may make contact with … 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.
WebAug 9, 2016 · Resistance spot welding (RSW) is widely used in the automotive industry [], however, its welding and joining quality is heavily influenced by various disturbances, such as shunting [2, 3], small edge distance [], greasy surface [], poor fit-up [], electrode wear [], and so on.In recent decades, many kinds of dynamic signals during the spot welding … WebAug 2, 2024 · Accordingly, when adaptive control welding is performed with the cumulative amount of heat generated that is obtained by the test welding being set as the target in the case where a disturbance is present, e.g. in the case where the effect of current shunting is significant, the welding current is excessively large in a state in which the ...
