DRIVING DEVICE FOR WELDING TORCH OR THE LIKE

摘要

PURPOSE:To provide a titled driving device which is suited particularly for circumferential welding and gas cutting work of a circular hole, by having a driving mechanism which drives a support mechanism for a welding torch or the like disposed on a rotary wheel rotated and driven on the outside or inside of a stationary wheel in the diametral direction and a control mechanism which synchronizes the driving in the diametral direction of said support mechanism. CONSTITUTION:A driving device 4 is fixed in the position where the center thereof is made approximately coincident with the center of a circular weld line in the case of performing welding work for the circular weld line. The welding route at the groove center is determined by a method such as teaching and is once stored in a storage means. The welding for the 1st layer is accomplished in accordance with the storage circuit in which said route is stored. A control device in this case is required to have just the function of synchronizing and controlling the rotation and driving of a rotary wheel 2 and the diametral driving of a welding torch 5 by a diametral driving mechanism 4. Multilayered build-up welding is also accomplished by the similar operation.
