| Description : |
It is a heavily coated, Ni-Cu alloyed basic electrode It gives a weld metal that has an excellent corrosion resistance to sea water and to flue gases.
High mechanical properties with excellent crack resistance of restraint conditions. It welds with a quite, stable arc giving very little spatter.
Metal recovery approx. % 115, easy welded in all positions except vertical down. Deposit gave very low hydrogen content. Re-drying is 350°C-400°C min. 2 h.
|
|
| Application : |
The electrode can be used in all positions for the welding of all types of joints. It is particularly designed for welding the shell platings of hips where the protective paint coating wears severely. It is used for welding weathering structural steels, Ship steels of A-, D- and E- quality and slow corrosion steels ( due to its copper content ) of the CORTEN - A and CORTEN - B type are among other application areas. It can be used in the welding of parts that work under dynamic loads at elevated temperatures; in all construction applications including bridge, boiler and pressure vessels, and shipbuilding. It can also be used in the root pass.
