Weld splash
Weld splash (expulsion/spatter) happens when molten material comes out from the weld nugget. It causes cosmetic problems, defective welds, safety issues for workers, and maintenance problems in the production line. Weld splash is one of the most common issues in the welding industry. Why does weld splash happen? There are many causes of splashes. The … Continue readingSelecting parameters that cover sheet gaps for stable production
Gap between welding parts can cause unstable welding production such as, early splash, no weld due to bad contact or improper gap closure. This case study shows how the gap size affects the splash limit and the lower limit of process window.
The critical role of hold time in weld quality and performance
Optimizing hold time shapes cooling rates, hardness distribution, and fracture behavior in resistance spot welds. This case study explores the effect of hold time on hardness and strength of weld nugget.
