Low Temperature Steel Welding Electrode
W606Fe
GB/T E5518-C1
AWS A5.5 E8018-C1
Description: W606Fe is a low-temperature steel electrode with iron powder and a low hydrogen potassium coating. It can be used for all-position welding with AC and DC. The deposited metal has good impact toughness at -60°C.
Application: Used for welding low temperature steel such as 2.5Ni.

Notice:
1. The electrode must be baked for 1 hour at 350℃ before the welding operation;
2. It is essential to clean up rusty, oil scale, water, and impurities on welding parts before welding.
