- 試驗證明，無弧光干擾時，對於V型、半V型、對接I型、U型、搭接等接縫重建精度很高，有弧光干擾時，對對接I型、U型重建效果欠佳。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.
