提出了适合于CO_2焊特点的接头形式,该接头形式在保证焊接质量前提下,减小了对接焊的坡口角度及角焊缝的焊脚尺寸,可以提高焊接生产率,降低成本。
A new type of joint suitable for CO_2 welding is proposed. Under the precondition of ensuring welding quality, the joint form can reduce the bevel angle of butt weld and the fillet size of fillet weld, which can improve the welding productivity and reduce the cost.
