Shunt effect in resistance spot welding

The shunt effect in resistance spot welding occurs when part of the welding current flows through previously made, closely spaced welds. This study investigates how the shunt effect behaves under different welding conditions.

Boosting production with energy efficiency in spot welding

Energy efficiency in resistance spot welding depends on choosing parameters that avoid unnecessary heat input. This case study uses four weld examples to show how total optimization reduces energy waste while preserving weld strength and process stability.

Selecting 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.

Process window and strength of steels

The weldability of material is different from each other. It also means each material has its own process windows.
