WELDED BUTT JOINT MANUFACTURING METHOD Russian patent published in 1994 - IPC

FIELD: welding of thin-walled joints. SUBSTANCE: method involves overlapping edges of sheets to be welded for a value exceeding cross shrinkage value of sheets upon welding and less than value, at which plastic deformation at the area of sheet bend occurs; pressing sheet edges together; positioning stop between sheet edges and displacing it in the direction of welding, so that stop spreads the edges aside and spring-biases them; conducting welding of edges at the place, where they are brought together, with welding being effectuated without additional wire. EFFECT: wider operational capabilities and enhanced reliability of joints obtained. 4 dwg
