Traditional resistance spot welding (RSW) has been unsuccessful in forming quality composite joints between steel– or aluminum–polymer-based composites. This has led to the development of spot welding variants such as friction stir spot welding (FFSW), ultrasonic spot welding (USW), and laser spot welding (LSW). The paper reviewed the differences in...Read More

Studies were carried out on the force profiles of the pneumatic electrode actuation system and servo electrode actuation system to analyse their effects on weld strength. The studies were carried out at three different locations of the weld lobe; below the lower limit, between the lower limit and upper limit...Read More

Resistance spot welding is a process which is widely used in the automotive industry to join steel parts of various thicknesses and types. The current practice in the automotive industry in determining the welding schedule, which will be used in the welding process, is based on welding table or experiences....Read More

Resistance Spot Welding (RSW) is a process that is widely used in the automotive industries. The parameters that are used to develop a spot weld are the welding current, weld time and electrode force. Electrode force was not used as a control parameter due to the use of pneumatic system...Read More

Resistance spot welding (RSW) is an essential welding technology today for joining two or more metals in various manufacturing industries. A statistic shows that one metal assembly out of five is joined using resistance spot welding mechanism, commercially. It uses traditionally two electrodes to hold the metal sheets and forces...Read More
