As a solid-state bonding technology, ultrasonic welding (USW) has the characteristics of
green energy saving and environmental friendliness. It is more suitable for joining dissimilar …

The lap joints of 6061-T6 aluminum alloy/Q235 steel were obtained by conventional friction
stir welding (FSW) and ultrasonic vibration enhanced friction stir welding (UVeFSW). The …

As lightweight automotive structures improve fuel efficiency and reduce carbon dioxide
emission, they have garnered extensive attention. Vehicle mass reduction, which is a key …

This work focused on the effects of using different electrode combinations on the welding
process and welding quality during aluminum/steel resistance spot welding (RSW) process …

To enhance the performance of resistance spot welded joints between aluminum alloy (AA)
and mild steel (MS), a specific electrode termed embedded composite electrode was used …

Resistance element welding (REW) has recently attracted increasing interest, especially in
the joining of high-strength steels and aluminum alloys. However, the intensity of heat input …

Because aluminum and steel have different characteristics, directly joining them one cannot
obtain desired Al/steel welded joint. In order to improve the Al/steel resistance spot welding …

In this study, Al joint systems without heat-affected zones (HAZ) were developed on Al/Fe
alloy lap joints fabricated by resistance element welding (REW). The robustness of the joints …

In-service patch welding is frequently used to repair corroded or damaged steel structures.
However, the repair welding may adversely affect the long-term mechanical integrity of the …

DP780 steels and 6061‐T6 aluminum alloys are joined using the resistance element
welding (REW) process with a flat Q235 rivet. The macrostructure, microstructure, and …
