AWS E7011-G is a kind of carbon steel electrode with high cellulose potassium type coating specially used for vertical downward welding. AC/DC. It has strong welding arc, deep penetration. It can weld in the bottom with back information. It has fast speed during welding process.
Applications: Suitable for vertical down welding structures, made of carbon steels and low alloy steels, eg. Pipes.
Instructions:
It is not necessary to be baked before welding. But If the electrodes are affected with damp, they must be baked at 150º C for 30-60 minutes before welding.
