Abstract

1277117 Making screwdrivers; screwdrivers; welding by pressure or fusion STANLEY WORKS (GREAT BRITAIN) Ltd 12 Oct 1970 [5 Dec 1969] 59436/69 Headings B3A B3N and B3R A screwdriver has a preformed section W 1 welded to a shank section W 2 . The section W 1 preformed by forging, machining or powder metallurgy is joined to the shank section W 2 of a similar or dissimilar metal by friction welding (as shown), butt welding, electron beam welding or plasma arc welding. After welding, the joined sections are rotated by a chuck c and the flash g trimmed by a cutting tool f.
