The results showed that there were two kinds of defects, porosity and ill bonding in the laser multi-layer cladding.
结果发现，成形件内部存在两种类型的缺陷，即气孔和熔合不良。
The transverse crack in surfacing layer, porosity in bead edge and non-fusion between layers are the defects that are liable to produce when multi-layer surfacing is used.
多层堆焊时，易产生堆焊层横向裂纹、焊道边缘气孔及层间结合不良等堆焊缺陷。
