埋弧焊丝偏移对焊缝质量的影响

针对厚度小于20mm钢板在双面埋弧焊接生产中出现的焊丝偏移接缝中心,造成层间未焊透缺陷的问题进行了试验,试验表明在一定焊接规范条件下,焊丝偏移会引起焊缝尺寸的变化并给焊缝质量带来影响,找出产生缺陷的原因和防止产生缺陷的措施。

Influence to Welding Quality Caused by Submerged Arc Welding Wire Deviation

It aims at the thickness the smaller the silk of welding that a steel plate appear in a submerged are weld produce is partial to move the joint center, resulting in the layer a problem for not welding deeply blemish proceeded to experiment, experimenting to express at certain weld the norm term next, the silk of welding be partial to move and would cause the variety that welding sew size and sew the welding the quantity bring the influence, finding out the reason that produce the blemish with prevent the measure that produce the blemish.
