Claim 13:
14. A method of controlling a welding station used for welding seams extending along cylindrical can bodies, the welding station comprising a pair of welding rolls and a calibration unit for causing a desired cylinder overlap during welding, the calibration unit being adjustable along at least three different adjustments axes, the method comprising:
monitoring welded seams and providing an electrical signal indicative of the weld thickness at a series of predetermined points along a seam length;
generating one or more control electrical signals in response to said electrical signal indicative of the weld quality of welded seams; and
providing the one or more control electrical signals to one or more of a plurality of adjustment mechanisms configured to adjust the calibration unit relative to one or more of the three adjustment axes, to cause the desired cylinder overlap.
