ISO 14343-A-G 23 12 L
Description:
The main component of the welding wire is ultra-low C-22Cr-12Ni, which is a stainless steel MIG welding wire, which can be welded at all positions. Excellent welding workability - smooth wire feeding, stable arc, beautiful appearance, and minimal spatter; deposited metal contains proper amount of ferrite and has good crack resistance. Due to the high content of the alloy, the high temperature resistance is good; the carbon content is low, and the corrosion resistance is excellent.
Uses:
It is often used in the welding of carbon steel and stainless steel dissimilar materials, in the petrochemical industry such as the transition metal of the reaction vessel inner wall, or in the martensite and ferritic stainless steel with poor toughness.

Precautions:
1. Protective gas: Pay attention to the purity of the protective gas. The ratio of the mixture is recommended to be Ar+ 1 ~ 3 % O 2 .
2. Gas flow rate: 20 ~ 25L / min.
3. Dry elongation: 15 ~ 25mm.
4. Remove the rust layer, moisture, oil, dust, etc. from the welded parts.
5. When applying outdoor welding, when the wind speed is greater than 1.5m/s, windproof measures shall be taken, and appropriate windproof measures shall be taken to prevent the occurrence of air holes.
The above suggestions are for reference only, and the actual situation is subject to the actual situation. If necessary, perform process evaluation before determining the welding plan.
