Resistance spot welding

In addition, a simplified surrogate model for use in conjunction with coarse shell element meshes is also calibrated. Simulations are performed of all structural experiments to assess the range of validity of the detailed and simplified FE models. It is found that the detailed model captures the experimentally observed failure modes including changes in the location of fracture initiation as a function of the loading, while the simplified model is able to predict the spot weld strength with reasonable accuracy.

The complete bodyshell of most cars is built up from a variety of sections which are resistance welded together. This type of weld is more commonly known as a “spot weld” due to its’ appearance – a circular weld about 1/4” wide. Each section of a modern car contributes to the strength of the whole shell, so it becomes vital that if any of those sections are removed, a replacement must be welded securely back into position, using a similar number of welds in the same places as the originals, to restore rigidity. One noticeable trend of the last...

Mig spot welding, although sometimes considered a tacking tool, has gained wide acceptance as a methodof joining which is competitive with riveting and resistance spot welding. In some applications, it hasreplaced continuous welding methods as it provides reduced welding costs, reproducibility, and adequatestrength for the service requirements and requires minimum operator skill. Mild steel, stainless steel andaluminum are very commonly welded with this method
