Electrode degradation in the continuous resistance spot-welding process of baked hardening (BH) 220 steel was evaluated by an electrode life test, and weldability tests were conducted geometry feature measurement, mechanical property analysis, diameter measurement with 88 or 176 weld intervals. The analysis shows that heat-affected zone (HAZ) width, nugget diameter, area tend to decrease rapidl...

Numerous industrial applications, particularly those in the transport industry, require joining of dissimilar materials which offers considerable benefits terms low cost, design flexibility, and weight reduction for overall structures. The problems associated with conventional fusion welding processes have stimulated researchers recent years to develop new methods are difficult join. Friction s...
