all kinds of welding methods are difficult to produce defectsin welding, according to the existing parts can be divided into twotypes of surface defects and internal defects.

必须严格控制，但不同的缺陷的危害程度有差异，裂纹，未焊透和未融合石不允许存在的严重缺陷，必须返修除掉，有许多焊接缺陷是各种焊接方法中共有的。

must be strictly controlled, but the degree of harm ofdifferent defects are different, crack, lack of penetration andlack of fusion stone does not allow the existence of seriousshortcomings, must rework away, there are many kinds of weldingmethods welding defects are common.

熔化金属冷却过快，熔渣来不及浮出，焊件边缘清理不净和层间熔渣未完全除掉以及电流太小和焊速太快等均会促使夹渣的形成

the molten metal cooling too fast, too late to welding slag,clean edge formed net and interlayer slag is not completely removedand the current is too small and too fast welding speed etc. willlead slag

未融合产生的原因主要是电流过小或焊速太快，因热量不足。

the main reason for the fusion is the current is too small ortoo fast welding speed, due to insufficient heat.

使母材坡口或先焊的焊缝金属未得到充分的熔化，或操作不当喝磁偏吹使电弧热偏于一侧，而另一侧没有熔合。

the weld metal weld groove or has not been fully melted orimproper operation of magnetic blow the arc hot drink is partial toone side, and the other side without fusion.
