JQ.H0Cr21Ni10 Stainless steel gas shielded solid welding wire in barrel

1. Shielding gas: Pay attention to the purity of the shielding gas, and the recommended gas mixture ratio is Ar+1-3%O2.

2. Gas flow: 20-25L/min.

3. Dry elongation: 15-25mm.

4. Really remove the rust layer, moisture, oil, dust, etc. on the welding part.

5. During outdoor welding, when the wind speed is greater than 1.5m/s, windproof measures should be taken, and appropriate windproof measures must be taken to prevent the occurrence of blowholes.
