Welding annular component onto support by industrial robot - moving welding head in welding plane about partial circuit matching number of burners

摘要

A circular component (9) with a central hole is welded on to a support (10) by means of an industrial robot, on the arm (7) of which is a welding head with at least two welding electrodes (1a,1b), adapted to the periphery of the component. The electrodes are separated by partition plates (5), having a centring pin (6) between them. The welding head turns round a partial circle, dependent on the number of welding electrodes to form the weld. ADVANTAGE - Simple and rapid welding process.
