Abstract Scope |
Aluminum spot-welding has always been a challenge. Since oxidation starts after it’s made, every time spot welding tips clamp down and heat up, an oxidation layer sticks to them. This process compounds with each weld, accumulating layers that act as an insulator that causes the tips to stick and affects weld quality.
This means tips need to be regularly dressed and replaced, adding up to substantial material and labor costs. What if the spot-welding process could be modified to extend the time between dressings and the lifespan of the tips?
This presentation will examine a testing case study of an aluminum spot-welding method that turns the gun to naturally abrade the tips as it applies current, prolonging time between dressings and replacements while improving weld quality. The speaker will walk through the process, materials, thickness and variants to provide actionable advice on how this can be applied to daily applications. |
