Influence of welding current shape on expulsion and weld strength of resistance spot welds

Science and Technology of Welding and Joining, 2006
The present paper presents the influence of welding current shape on weld strength of resistance spot welds of zinc coated mild steel sheets. The influence is analysed at different levels of the electrode wear. Welding currents with different peak values and different RMS (root mean square) values were used in the experiment.

Geometry of Pulse Current GMA Weld

2017
Variation in geometry of P-GMA weld as a function of pulse parameters has been discussed in order to understand the control of welding process to produce desired weld geometry of required chemistry for an acceptable weld quality. The mechanism of the control of weld geometry governed by its basic aspects as penetration, width, reinforcement, form ...
