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 … WebSep 28, 2024 · Although short-pitch resistance spot welding (RSW) significantly increases vehicle body strength, its application has been limited because of the associated shunting effect. In this study, a reference-based adaptive RSW process intended to minimize the shunting effect was proposed, and a related RSW system that controls welding current …

Increasing the welding current is an effective method to overcome the shunting effect. This paper studies the shunting characteristics of resistance spot welding in unequal-thickness 2219 and 5A06 aluminum alloys when three spot welds are arr
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. WebMay 23, 2024 · Spot welding is a resistance welding process that joins metals together by applying pressure while supplying electric current to the weld area. It was first introduced in 1885 when Elihu Thomson accidentally fused two copper wires together in an experiment. Spot welding has become a staple welding process in manufacturing and assembly ...
