Paper Title:
Expulsion in Resistance Spot Welding of AZ31B Magnesium Alloy
  Abstract

Expulsion is undesirable during the resistance spot welding due to the weld quality decrease. The expulsion happening during the resistance spot welding of AZ31B magnesium alloy was studied related to the distribution of maximum temperature in the interface due to the existing of contact resistance, and connected with the increased pressure in the nugget due to melting and expansion of liquid metal. The influence of welding parameters on expulsion is presented and discussed in this investigation.
