Abstract

During resistance welding, weldment materials collapse when they near their melting temperatures. This collapse causes a reduction of contact area and pressure between the weldment materials and the welding electrode if the electrode cannot follow the collapsing materials fast enough. This reduction of contact area and pressure can result in unsatisfactory welds. In a welding electrode arrangement for overcoming this problem, electrode 10 is mounted at the end of spring cantilever beams 12 and 14. These are loaded with a specified weight 16 at their root mount. The mass of beams 12 and 14 and particularly that of electrode 10 is minimized. Thus the spring action of the beams provides fast follow-through as the work pieces 18 and 20 deform or collapse during the welding operation.

Welding Electrode

During resistance welding, weldment materials collapse when they near their melting temperatures. This collapse causes a reduction of contact area and pressure between the weldment materials and the welding electrode if the electrode cannot follow the collapsing materials fast enough. This reduction of contact area and pressure can result in unsatisfactory welds. In a welding electrode arrangement for overcoming this problem, electrode 10 is mounted at the end of spring cantilever beams 12 and 14. These are loaded with a specified weight 16 at their root mount. The mass of beams 12 and 14 and particularly that of electrode 10 is minimized. Thus the spring action of the beams provides fast follow-through as the work pieces 18 and 20 deform or collapse during the welding operation. To further minimize the moving mass during this follow- through, electrical connections to the electrode are made via the beams themselves. The cantilever beams act as a spring which is released when the weldment collapses. Since the cantilever electrode can be very light, the follow- through from the initial position indicated at 22 can be extremely fast.
