摘要
The laser-arc hybrid welding was carried out on the marine-use steel, and the effects of primary parameters on weld behavior were investigated. The results show that the weld penetration increased gradually with the increase of laser power. Meanwhile, superior weld formation, penetration and reinforcement were achieved when laser and wire distance was 2 mm. The weld width, penetration and reinforcement were increased with the increase of current, while they were decreased with the increase of welding speed. The influence of laser power on the generated microstructure was analyzed by the observation in junction of weld and heat affected zone (HAZ). The microstructure of HAZ coarsened with the increase of laser power, which is consistent with the hardness distribution trend in HAZ.
