The position of the welding roll (WR) has an influence on the overlap at the beginning and at the end.
| WR slightly too high | = Overlap at the beginning less |
| WR slightly too low | = Overlap at the beginning constant |
| WR higher | = Overlap at the end better |
| WR lower | = Overlap at the end less |
| WR lower | = Overlap at the beginning less |
