Answer:

6010 and 6011 Electrodes for welding galvanized steel.

Weathering steel, best-known under the trademark COR-TEN steel and sometimes written without the hyphen as "Corten steel", is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years.

The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words, the steel is allowed to rust in order to form the 'protective' coating.

For welding corten steel:

1 A.W.S Classification E 7018 - 1 AWS A 5 - 1 - 78
2 IS classification E 5424 JX IS 814 (Part I & II)H
