焊剂带约束电弧超窄间隙焊接根焊方法
Root welding of ultra-narrow gap welding with arc constricted by flux strips
摘要
Abstract
Ultra-narrow gap welding has unique advantages in the butt welding.Root welding is generally required to complete by using the method of one-side welding both sides formation.By using ultra-narrow gap welding with arc constricted by flux strips, experiments of root welding with flux backing laid on the copper plate were carried out.By choosing reasonable matching of voltage and current,welding groove roots could be fused effectively with arc constricted by flux strips.Flux could be prevented from excessive burning loss because of heat concentrated with fast cooling of copper plate, and then made the molten pool not fall off to ensure good seam formed of back by flux backing.One-side welding both sides formation could be achieved by use of constricting arc with flux strips in ultra-narrow gap.关键词
