| Abstract: | In order to solve the problem of surface porosity in laser arc hybrid welding of marine sheet metal,the single variable method was used to design the process test.The basic law of surface porosity was analyzed by changing the laser power,wire feeding speed and welding speed.The results showed that when laser arc hybrid welding is used to weld AH36 class 6 mm sheet metal,when the ratio of wire feeding speed and welding speed is about 1.5,the surface forming effect is good and there is no porosity. |
