In laser welding, shielding gas affects weld formation, weld quality, weld penetration and weld width.laser welding solutions, In most cases, blowing shielding gas will have a positive effect on the weld.

Let's look at the positive effects

1) Correctly blowing in the protective gas will effectively protect the molten pool from reducing or even avoiding oxidation;

2) Properly blowing in the protective gas can effectively reduce the spatter generated during the welding process;

3) The correct purging of the protective gas can promote the uniform spreading of the molten pool during solidification, so that the weld is formed uniformly and beautifully;

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