RISExpulsion Intensity Monitoring and Modeling in Resistance Spot Welding Based on Electrode Displacement Signals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Weld expulsion is one of the most common welding defects during the resistance spot welding (RSW) process, especially for high strength steels (HSS). In order to control and eventually eliminate weld expulsion in production, ...
A Novel Expulsion Control Strategy With Abnormal Condition Adaptability for Resistance Spot Welding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Welding expulsion is a common problem in the resistance spot welding (RSW) process, which severely impacts weld quality and surrounding facilities. Existing expulsion control strategies are ineffective for complex and ...
Improving Weldability of Press Hardened Steel Through Combining Stepped Current Pulse and Magnetically Assisted Resistance Spot Welding Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Press-hardened steel (PHS), characterized by its extremely high strength, has wide applications in vehicle body manufacturing as an innovative lightweight material. Nevertheless, the poor weldability of PHS results in poor ...
