Abstract

312,027. Hume, W. R. May 21, 1928. Divided on 311,946. Drawings to Specification. Uniting by fusion. - In making- sheet metal pipes &c. by bending a blank into tubular form with its longitudinal edges spaced apart, the edge portions are pressed against an abutment so as to cause them to be brought into and held in coinciding arcuate formation with the edges themselves closely abutting against each other preparatory to being temporarily or permanently united. The edges may be tack welded whilst held in this manner and subsequently joined by a continuous line weld. The apparatus is fully described in Specification 311,946, which is referred to.
