Abstract

629,687. Welding. SOC. L'AIR LIQUIDE, SOC. ANON. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES G. CLAUDE. March 17, 1947, No. 7353. Convention date, March 23, 1946. [Class 83 (iv)] In pressure-welding parts A, B, 1 to 10 mm. thick, the facing edges C are fused in a reducing oxyacetylene flame and butted, the flames initially passing between the parts and being partly retracted on butting to maintain the reducing action. A plurality of water-cooled burners C1, C2 are aligned with the joint and may be reciprocated to ensure uniform heating and mixing of the flames from the burner nozzles up to 3 mm. apart. The parts A, B are spaced from .5 to 3 mm., and may have bevelled edges. Pipes may be rotated during welding.
