ABSTRACT:
A short-cycle arc-welding system (10) and a method for welding elements (32), such as metal bolts (32) to components (34) such as sheet metal (34) includes a robot (12), having at least one arm (16) displaceable on at least two co-ordinate axes (x, y, z), a welding head base (20) fixed to robot arm (16), a welding head (22) displaceably mounted on welding head base (20), a retaining device (30) retaining an element, a lifting device (36) for setting and re-positioning retaining device (30) in relation to welding head (22), and a measuring system (44,46) determining the relative position between component (34) and element (32). Measuring system (44,46) has a control device (46), controlling lifting device (36) such that element (32) displaces towards component (34) until contacting component (34) to determine the relative position.
