Abstract

The invention relates to a welding torch (100; 200; 300; 400) for MIG/MAG welding with a number of welding electrodes in the same molten pool, comprising means (190; 290; 390) for adjusting the relationship between lengths of electrode projection from two or more contact nozzles. The invention also relates to an installation comprising a manipulator, such as an industrial robot, and a welding torch of the type described above, where the manipulator comprises a control system for controlling programmed relative movement between the welding torch and the joints of the object being welded, and where the control system also comprises a first control device adapted for adjusting the relationships between the length of the electrode projections from different contact nozzles during welding and/or a second control device adapted for adjusting the spacing between the points at which different arcs meet the molten pool during welding.
