DESCRIPTION
ER70S-6 – is mild steel type welding material designed for joinging of most carbon and low alloyed steels. It contains high levels of manganese and silicon, which increase deoxidizing power and fluidity of the weld pool. ER70S-6 can be characterized by excellent arc ignition, extremely low overall spatter, stable arc with low feeding force, high current applicability, low fume emission. It is excellent where poor t-ups or rusty and oily plates maybe used.
Typical application of ER70S-6 – installation works, manufacturing of pressure vessels, construction of steel structures, boiler fabrication, automotive, agricultural machinery, and etc.
