在工厂焊接容器壳体或锅炉汽包等筒形零件的环焊缝时,多采用手工电弧焊焊接内环缝,外环缝采用埋狐自动焊的方法施焊。为了焊内环缝,工人钻进钻出筒体,劳动条件极差,工作效率低,产品质量也不稳定。为了解决这一问题,我厂采用了埋弧焊焊接内环缝,并设计了一种简易的焊接衬垫,解决了焊缝容易焊漏和烧穿问题。具体结构如下图所示。 In the factory welding container casing or drum drum and other cylindrical parts of the welding seam, the use of more manual arc welding inner ring seam, the outer ring seam welding method using automatic welding of fox. In order to weld the seam, the workers drilled into the cylinder, poor working conditions, low efficiency, product quality is not stable. In order to solve this problem, our factory adopted the submerged arc welding inner ring seam, and designed a simple welding pad to solve the problem of easy welding seam leakage and burn through. The specific structure as shown below.
