AWS A 5.5: E 8018 - C1 |
Description |
A basic heavy coated iron powder type low hydrogen electrode for joining of nickel steels having 2 to 3% 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 etc. |
