AWS A 5.5: E 8018 - C2 |
Description |
A basic heavy coated iron powder type low hydrogen electrode for joining of nickel steels having 3 to 3.75% nickel. The electrode is having very good operating characteristic like controlled molten slag-metal weld pool, easy positional welding capability and good slag detachability. Weld metal is of high radiographic soundness |
Application |
Suitable for fabrication of cryogenic vessels like storage tanks of liquefied gases, oil refinery valves, pressure vessels, construction of components subjected to low temperature services in petrochemical industries, locomotive main frames, truck and side frames etc. |
