Compensation of  heat induced weld distortion   

Initial situation:
It is well known that weld distortion is caused by the heat generated in the course of the welding process. Deviations of the welding path are possible in all three directions, so that the process does not take place at the optimum position of the gap, and also the geometrical shape of the object finally may change. This problem results in reduced stability, rework cost and even rejections. Remedy by inline welding seam correction on the basis of QuellTech laser scanners proves to be a meaningful approach.
