<p>The method involves forming two axial offset blind bores with a flat base. Smooth pins (5) are chosen and introduced in the bores, after mounting inner elements (4) of a strap e.g. rigid/articulated metal strap (1), on the pins. The pins and the elements are welded by carrying out electron beam bombardment on upper/lower wall of outer elements (2, 3). A termination operation is performed on the bombarded wall to remove a welding seam. The bore formation, pin choosing and introduction, pin and outer element welding and operation performance are carried out to fix the pins on the outer elements.</p> |
