The role of correct blowing in the use of laser welding machine

1. Correct blowing into the protective gas will effectively protect the weld pool to reduce or even avoid oxidation;

2. Correct blowing into the protective gas can effectively reduce the splash generated in the welding process;

3. The correct blowing into the protective gas can make the weld pool solidification evenly spread, make the weld forming uniform and beautiful;

4. Proper blowing of protective gas can effectively reduce the shielding effect of metal vapor plume or plasma cloud on laser, and increase the effective utilization rate of laser;

5. Proper blowing of protective gas can effectively reduce the porosity of weld.
