Problem If the final closing of the tube is done imprecisely, the weld edges meet at the wrong angle or gap, producing off-center seams, poor penetration and out-of-round pipe. Cause The last forming passes determine the weld edge geometry, so any overshoot or undershoot there cannot be fixed by the welder and shows up directly as seam defects. Solution The ZY16 finishes forming in three precision stands that set the exact edge gap and approach angle before the weld point.
