摘要
针对钻具钻铤修复过程中打底焊道电弧不稳的问题,采用工频感应圈点动加热的方法消除剩磁,有效地解决了电弧不稳问题,为类似焊接件的修复提供了参考。
In order to overcome arc drifting phenomenon during repair welding process for oil drilling tappets, the line-frequency induction coil has been used to heat the area to be welded, So that the residual magnetism is eliminated. In this way, the arc stabilization is reached, and a reference is provided for the repair welding of similar parts.
