$CO_2$ 레이저-MIG 하이브리드 용접부 용입깊이에 미치는 레이저 및 아크 출력의 영향

Effects of laser and arc power on the penetration depth in $CO_2$ laser-MIG hybrid welding

The potential advantages of the hybrid welding process are improved weld penetration, enhanced gap tolerance, control of weld metal composition, and improved weld quality in comparison to laser or arc welding. Especially, the deep penetration of hybrid welding is very attractive in welding of thick plates. In this study, therefore, the influence of arc power in hybrid welding on detailed bead dimensions at different laser power levels was investigated.
