The maximum penetration depth of gas flow is increased with the increase of gas momentum while the diameter of oxigen gunjet keeps constant.
气流的最大穿透深度随气体动量的增加而增加，而氧气喷枪的直径保持恒定。
The results show that the maximum penetration depth of gas flow is increased with the increase of gas momentum while the diameter of oxigen gunjet keeps constant.
研究表明，当喷枪直径一定时，气体的最大穿透深度随气流动量通量的增加而增大，当动量通量相同时，液体的黏度越大，气体的最大穿透深度越小。
The penetration depth of weld metal can be increased by selecting correct gas-assisting blowing in laser welding.
