0.8 mm~3.2 mm Sino Erli MG309LSi mig Ar/Co2 stainless steel 309 welding wire S309 ER309

The main component of the welding wire is ultra-low C-23Cr-13Ni, which is a stainless steel MIG welding wire. It can be welded in all positions. Due to the addition of Si, the molten iron has good fluidity, so the forming is more beautiful, the wire feeding is smooth, the arc is stable, and the splash is minimal. Because of its low carbon content, it has excellent corrosion resistance.
It is often used in the welding of dissimilar materials of carbon steel and stainless steel, the transition metal welding of the inner wall of the reaction vessel in the petrochemical industry, or the welding of martensitic and ferritic stainless steels with poor toughness

Attention:

1. Shielding gas: pay attention to the purity of the shielding gas, the recommended mixture ratio is Ar+1~3%O2.
2. Gas flow: 20~25L/min.
3. Extension elongation: 15~25mm.
4. Remove the rust, moisture, oil, dust, etc. from the welding part.
5. When welding outdoors, wind-proof measures should be taken when the wind speed is greater than 1.5m/s, and appropriate wind-proof measures must be taken to prevent air holes.
