Shunting welding

WebOct 1, 2024 · Abstract. A reference-based adaptive resistance spot welding (RSW) method intended to reduce the shunting effect in short-pitch (≤40 mm) RSW is proposed in this study. As the weld pitch decreases, the nugget diameter and dynamic resistance level concurrently decrease by an amount equivalent to the increased shunting effect. 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 …
