METHOD OF MANUFACTURING CLOSED BENT THIN-WALL WELDED PROFILES Russian patent published in 2008 - IPC B23K101/04 B21C37/08 B21D5/06

Abstract RU 2334607 C2

FIELD: technological processes.

SUBSTANCE: open profile with ribbed, crimped or other surface is formed in automatic line profile-bending mill of a coiled stripe without preceding heating. Final forming of closed profile is performed in seam-pressing gauge. Edge for welding is prepared, overlapping welding is performed with overlap melting without additive materials. The stripe is moved guiding shaft connected to electric profile-bending mill engine, with continuous control of welded junction quality and data transfer to computer.

EFFECT: improved quality of welded junction.
