ARC SEAM SENSING - PRECISION WELDING OF FILLET AND V-SEAMS During the welding process arc seam sensing is used to compensate for positional tolerances of the welding seam. By means of a special software and specifically designed hardware, the "actual" seam position of fillets and V-shaped joints is computed by processing data measured, while arc weaving gives a corresponding shift of the original programmed point(s) to the true seam position. This arc seam sensing technique can be used with a complete range of welding transfers such as short arc, spray arc and pulsed arc welding - using single or Tandem applications. The welding torch then follows the path of the seam joint exactly. This process can be advantageous in combination with gas nozzle sensing. There, the starting point of each welding seam is detected by the sensor and the arc is ignited at the correct position with the desired stick-out. igm is providing turn-key robotic welding solutions tailored to the customers needs and products.
