RISA Comparative Study of Self-Piercing Riveting and Friction Self-Piercing Riveting of Cast Aluminum Alloy Al–Si7Mg
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cast aluminum alloys are promising materials that can simplify the manufacturing process of automobile body structures. However, the low ductility of cast aluminum poses significant challenges to existing riveting technologies. ...
Improvement of Single-Sided Resistance Spot Welding of Austenitic Stainless Steel Using Radial Magnetic Field
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Magnetically assisted resistance spot welding (MA-RSW), which uses a pair of mutually repulsive ring-shaped axially magnetized magnets, has been demonstrated to have significant effect on weld quality of high strength ...
Microstructure and Mechanical Performance of Cold Metal Transfer Spot Joints of AA6061-T6 to Galvanized DP590 Using Edge Plug Welding Mode
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dissimilar joining of aluminum to steel poses a challenge for arc welding. In this study, aluminum AA6061-T6 and hot dipped galvanized DP590 steel were joined using the Fronius cold metal transfer (CMT) welding process ...
Effect of Rivet Hardness and Geometrical Features on Friction Self Piercing Riveted Joint Quality
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conventional magnesium alloys, due to their low ductility, have a poor selfpiercing rivetability. Cracks always occur when the magnesium sheet is placed at the bottom layer, which brings great challenge to the use of the ...
Thermally Assisted Self-Piercing Riveting of AA6061-T6 to Ultrahigh Strength Steel
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Self-piercing riveting has been widely used in vehicle body manufacturing to join aluminum alloys or aluminum to steel. However, it is difficult to rivet ultrahigh strength steel (UHSS) because of its resistance to piercing ...
Expulsion 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 ...
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 ...
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 ...
Curing-Induced Debonding and Its Influence on Strength of Adhesively Bonded Joints of Dissimilar Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Adhesive bonding is thought to be a suitable method for joining dissimilar materials, such as aluminum to steel in multimaterial car-body manufacturing, but when it is combined with other joining methods, such as spot ...
