Long Life Resistance Welding Electrode Project


Objective

The overall objective of the ORNL task is to develop computational model that describes the electrode wear behavior during resistance spot welding of galvanized high-strength steel.  This model will be developed to support the Long Life Electrode (LLE) Project under Advanced Materials Division (AMD) of USCAR organization.  The ORNL model will track the electrode deformation characteristics that leads to electrode wear.  This model will consider the interactions between rapid thermal cycles, loading conditions on the deformation and microstructure evolution in various copper alloys, including existing and new development alloys.  The model will be evaluated with the experimental data generated by the USCAR organization.  The model will be designed in a modular fashion so that it can be easily extended to spot welding conditions of aluminum alloy.
