FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to gas-flame straightening of welded structures. Torch comprises, at least, two nozzles arranged at angle to diverge along flow direction for processing two aiming points located close together. Method of straightening is realised with the help of said device. Proposed device may be used for straightening thin-wall sheets or channels and structural components welded by laser or laser hybrid welding.
EFFECT: expanded performances.
