Abstract
The device includes a support which carries a roller retaining the molten metal in the gap until it solidifies. The roller may be pressed against the pool; or two rollers may be used, one on each side of the gap. The support pref. travels along a rail, and carries a welding burner located just in front of roller, so the latter can roll over the pool move with the burner; and a weld pool retention pad can be located under the root of the weld. The support pref. also includes a spring-loaded plunger pressing against a forked lever carrying one or two rollers so the latter are kept in contact with one or both sides of the gap. The molten weld metal is retained in the gap in all welding positions, e.g. in vertical or overhead welding.
