WebThe results (Fig. 5) showed that comparatively lower welding currents result in lower heat input and, consequently, a significantly smaller heat-affected zone. On the other hand, too high weld currents may lead to thermal damage of resistance element welded joints. Download : Download high-res image (480KB)
