Specifications:
- AWS: A5.20 : E-71T-5C/5M
DESCRIPTION AND APPLICATION
- ZIKA-71T5 is an all-position flux-cored wire designed to be used with CO2 or Ar/ CO2 gas mixture for 490N/mm2 grade high tensile steel.
- Its low temperature impact toughness is better than ZIKA E71T-1(AWS A5.20).
- The typical applications of ZIKA-71T5 are constructional steel, machinery and shipbuilding.
-
Use CO2 as shielding gas.
- Keep inter-pass temperature under 150℃ whiling in multiple-pass welding.
