Specifications:
- AWS: A5.20 : E-71T-1M
DESCRIPTION AND APPLICATION
- ZIKA-711M is a flux-cored wire designed to be used with Ar/ CO2 gas.
- It’s available for all-position welding with both single and multiple pass welds on mild and 490N/mm2 high tensile steels.
- It provides good impact properties, less fume, stable arc, easy slag removable and excellent X-Ray inspection.
- Typical applications include shipbuilding, storage vessels, structural fabrication, machinery and piping etc.
- Use 75~85%Ar+25~15%CO2 as shielding gas.
- Keep dry during handling and storage.
