? Wheel speed should be smooth and uniform. Creeping phenomenon is not allowed. ? Manufacture and assembly of precision welding roller frame should meet the national standard of 8 accuracy. ? Wheel frame should be made of high quality steel. Welded structure as a base, the need for post-weld stress relief heat treatment. ? Wheel frame must be equipped with a reliable means of conductive roller frame effect, does not allow the welding current flowing through the roller frame bearings. ? If the cylinder class anti-axial movement of the workpiece in the roller frame welding, the welding process in the whole axial movement of the workpiece should be ≤ ± 3mm.
