单面焊双面成形的焊接技术

Single-side Welding Technology with Double Sided Formation

本文主要针对低氢型焊条E5016[J506]在焊接时,通过改变焊接手法。采用直流反接由短弧操作用"一点焊法",在坡口大间隙的对接底层焊时。使焊缝背面成形美观,内部缺陷极少。获得更佳效果,为以后机电工程制造安装提供一种可行范例。

this paper E5016 low hydrogen electrodes J506] [in welding,by changing the welding technique.By using the dc operating with ＂a short arc welding method＂,the big gap in groove bottom welding joint.Make the weld appearance,the internal defects.Get better effect,manufacture and installation of electrical and mechanical engineering for example provides a feasible.
