Specifications:
- AWS: A5.22: E 309LMoT1-1
DESCRIPTION AND APPLICATION
- ZIKA 309LMo is a modified type of ZIKA 309L with the addition of molybdenum.
- It is suitable for joining stainless steels to unalloyed steels.
- The addition of molybdenum enhances creep strength and improves corrosion resistance.
- Before welding, the base metal should be cleaned from oil, rusty, moisture and the welding place should have the proper protection from the wind.
- Use 99.8% or higher purity CO2 as shielding gas. Maintain the flow rate no under than 20L/min when wire diameter is 1.2 or 1.6mm.
- Trailer Shield is required to ensure the weld pool completely shielded until solidification is complete and no porosity problem.
