Abstract
1. Способ многодуговой и лазерно-дуговой сварки, по которому корневой шов сваривают, используя гибридную лазерно-дуговую сварку плавящимся электродом, затем заполняют разделку электродуговой сваркой и последним сваривают внутренний шов электродуговой сваркой, отличающийся тем, что во время сборки заготовки с наружной стороны перед гибридной лазерно-дуговой сваркой корневого шва проваривают прихваточный шов, фиксирующий кромки заготовки между собой и полностью переваривающийся последующими сварками.2. Способ по п.1, отличающийся тем, что наружный и внутренний швы выполняются под слоем флюса.1. A method of multi-arc and laser-arc welding, in which the root seam is welded using a hybrid laser-arc welding with a consumable electrode, then the groove is filled by electric arc welding and the inner seam is last welded by electric arc welding, characterized in that during assembly of the workpiece from the outside before by hybrid laser-arc welding of the root weld, the tack weld is fixed, fixing the edges of the workpiece between each other and completely digested by subsequent welds. 2. The method according to claim 1, characterized in that the outer and inner seams are made under a layer of flux.
