Introduction & Characteristics:
AWS A5.20 E71T-1 is a gas-shieled and rutile type flux cored wire of 490MPa high tensile steel.
It showing us excellent welding performance,soft and stable arc,low spatter loss,easy slag removal,beautiful appearance of weld and high X-ray safety. Higher deposition rate particularly.Suitable for all-position welding.
Typical application:shipbuilding,offshore,bridge,pressure vessal and general fabrications.
Instructions:
1.The oil stains and rust on the weldments should be cleared away.
2. Designed for welding with 100% CO2.
3. When welding, the gas flow rate is generally 20~25L/min.
