Abstract

1509416 Controlling resistance welding FAEL SA 17 June 1975 [21 June 1974] 25809/75 Heading G3N A computer system controls the start and finish of continuous resistance welding, e.g. in the manufacture of barrels or tin plate cans. An alternating current roll welding machine has welding rolls 1, 2, a weld spot being formed during each alternating current half wave. Sheet metal strip stock workpieces 10 to be welded are moved towards the rollers by feed mechanism 4 and photo-cell 11 detects the leading and trailing edge. Computer 12, receiving welding frequency as a reference, then controls the feed speed so that the first weld occurs at a distance from the workpiece leading edge. Similarly, when the trailing edge is detected, computer 12 controls the welder drive motor 3 to ensure that the last weld spot lies at a distance from the trailing end. This is to prevent scorching or burning occurring at the leading or trailing edges.
