1、焊接缺陷 welding defects

在焊接过程中，由于受到材质、结构、工艺、操作等因素的影响，焊接接头区域常产生各种各样的缺陷，这些缺陷将直接影响焊接接头的使用寿命和安全。（For the effect of materials,constructure,procedure,operation and so on, the welding joint zone usually has all kinds of welding defects during welding, which will affect the using period and security of joint directly.）

1.1焊接缺陷的分类

（1）外部缺陷：咬边、焊瘤、弧坑、表面气孔、表面裂纹。

External defects: undercut,overip,arc pit, gas cavity in surface,crack in surface.

（2）内部缺陷：未焊透、未熔合、夹渣、气孔、裂纹、过热。

Internal defects:lack of penetration,lack of fusion,slag,gas pole,carck,overheating.

2、焊接检验 welding inspection
