The results show that when there is no welding arc, the accuracy of the seam reconstruction is very high. But when there has the disturbing of welding arc, the square joint and the U type joint cannot be reconstructed with high precision.

• 试验证明，无弧光干扰时，对于V型、半V型、对接I型、U型、搭接等接缝重建精度很高，有弧光干扰时，对对接I型、U型重建效果欠佳。
