Removable welding tip assembly

摘要

A dummy weld apparatus including a dummy weld gun which allows a direct weld robot with a conventional weld gun to clamp down on the dummy weld gun to apply force and weld current for performing welding of workpieces of a first composition (e.g., aluminum). This arrangement allows the current provided by the conventional weld gun to flow through the dummy weld gun for welding the workpieces using weld tips dedicated to welding parts of the first composition, but also allows the dummy weld gun to be removed from the conventional weld gun to allow the conventional weld gun to performing welding operations on workpieces of a second composition (e.g., steel) using the original welding tips of the weld gun, avoiding material contamination of the tips.

主权项

1. An apparatus for welding workpieces, said apparatus comprising:
a weld gun comprising:
a first weld tip and a second weld tip providing a welding current;a support structure for providing a compressive force by moving the first weld tip in at least a first direction towards the second weld tip; and a dummy weld gun comprising;
a first arm assembly;a first dummy weld tip held by the first arm assembly;a second arm assembly;a second dummy weld tip held by the second arm assembly; anda supporting structure connecting the first arm assembly and the second arm assembly, wherein the first arm assembly allows at least the first dummy weld tip to move in at least the first direction toward the second dummy weld tip; and wherein said dummy weld gun welds workpieces using both the compressive force in at least the first direction and the welding current, wherein the welding current and compressive force are both transferred from the weld gun to the dummy weld gun.
