igm gas nozzle searching - Tactile sensor for position detection This tactile sensor is used to determine the workpiece position or its components and individual parts by gauging the surface of the workpiece. In each case, the successional part of the program is shifted according to determined deviations. Sensor shifting may be applied for correction of an arbitrary amount of individual points, entire sections of a welding program or entire programs. Combination with arc seam sensing is feasible. The control system supports shifting, rotating, and tilting of a program, depending on position change. The gas nozzle itself is used as a sensor. This makes it possible - even on complicated workpieces and in confined spaces - to perform the required search steps on the reference surfaces of the workpiece, by which the position of the weld seams is determined. As soon as the gas nozzle gets into contact with the work piece, it is discharged and the robot stops immediately. This...

The welding torches are designed for use on robots for high-performance welding under harsh conditions. The slim design, together with the swan’s neck shape, permits the best accessibility even in narrow parts of the work piece. All welding torches provided as standard for igm robots have a particularly stable design with intensive water cooling and a quick-release coupling. They are also configured for pneumatic torch cleaning with compressed air at least 7 bar and for the use of the gas nozzle as a tactile sensor for program shifts. The arrangement of the contact tube in connection with the torch curvature ensures the forced contact of the welding wire. This ensures a uniform and constant current transition to the wire electrode under all conditions and wear conditions. Direct water cooling of the gas nozzle reduces the adhesion of weld spatter. The cooling water is routed through its own channels in the torch body up to the contact pipe, and from there through the nozzle stock...
