Abstract

The two metal sheets are lined to each other by welding both their leading and trailing edges. In the latter, at least one of the two curved contact each other on a narrow band. After metal deposition of the welding process, at least one of the bands is machine-finished to give it the required shape. Usually the internal metal a sheet is the one folded and machined after welding. Preferably the relative position of the sheets will leave the trailing edge outside the zone affected by the welding.
