  • Method of producing welded thin-wall straight-seamed tubes
    Patent number: 4400605
    Abstract: A method of producing welded, thin-wall straight-seamed tubes comprises forming a strip in rolls of a tube-forming mill into a tube skelp, and then subjecting the latter to the inert-gas-shielded non-consumable electrode welding. The tube skelp is formed with a gap between edges being 1/500 to 1/30 to the tube-diameter-to-wall-thickness ratio, taken in mm. The rate of welding and the level of welding current are selected in accordance with the rate of heat release in the welding zone, which should be sufficient to close joint due to heat expansion of the tube skelp material and the formation of welding joint.
