RISAsymmetric Nugget Growth in Aluminum Resistance Spot Welding With Multi-Ring Domed Electrodes: An Experimental Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Resistance spot welding of aluminum alloys (Al RSW) is known to be very challenging, in part due to the undesirable and hard-to-predict asymmetric growth of the weld nugget. In this paper, two 1.2 mm thick AA6022-T4 aluminum ...
Simulating Thermoelectric Effect and Its Impact on Asymmetric Weld Nugget Growth in Aluminum Resistance Spot Welding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Resistance spot welding (RSW) of aluminum–aluminum (Al–Al) is known to be very challenging, with the asymmetric growth of the weld nugget often observed. In this article, a semicoupled electrical–thermal–mechanical finite ...
