对接横焊板操作探析

Discussion on Butt-welding Operation in Horizontal Position Welding

针对对接横焊板操作中存在的电弧偏吹问题,简要介绍了电弧偏吹现象原理,通过改变试件接地线位置的方法,克服了焊接过程中产生的电弧偏吹问题,保证了焊接过程顺利进行,进一步阐述了操作过程和施焊工艺,在保证焊接接头各项机械性能都符合规定的前提下,使得试件正反面的焊缝外观检测符合要求。

The paper introduces the principle of arc blow, ing the position of the ground wire, then it describes the points out that the problem of operation process and welding mechanical properties of welding point correspond to the specification, but also makes the the requirements arc blow can be solved by chang- technology. It not only ensures the front and back of weld seam meetthe requirements.
