Theoretical analysis of shunting effect in resistance spot welding (RSW) of AA2219
Journal of the Chinese Institute of Engineers, Transactions of the Chinese Institute of Engineers,Series A/Chung-kuo Kung Ch'eng Hsuch K'an, 2016AbstractShunting effect is the loss of electrical current via the secondary circuit provided due to existence of previous nugget in a series of welding spots. This phenomenon is important for products containing intermittent spots. In this study, a theoretical model is developed for shunting effect in resistance spot welding for aluminum alloy 2219 ...

The metallic bump-assisted resistance spot welding (MBaRSW) weld formed between Al and steel had higher strength and better ductility than the RSW welds. The fracture behavior was investigated for both the RSW weld and MBaRSW/Al weld by printing metallic bumps on an Al sheet prior to welding.

Shunting phenomenon takes place when the electrical current passes through the prior weld spots. So far there have been few areas of the shunting impact studied while this is a prevalent effect in intermittent resistance spot welding (RSW). The magnitude of this current depends predominantly on distance, number, and the size of the previous spot welds.

Online Measuring Power Factor in AC Resistance Spot Welding
IEEE Transactions on Industrial Electronics, 2014 The power factor is a very important process variable in ac resistance spot welding (RSW) operation. Because of the variation of welding load during the welding process, the power factor is a time-varying variable.

There has been a substantial increase in the use of advanced high strength steel in automotive structures in the last few years. The usage of these materials is projected to grow significantly in the next 5–10 years with new safety and fuel economy regulations. Advanced High Strength Steels (AHSS) are getting popular with superior mechanical properties
