- Applications
- W 8016C2 is designed for welding of 3.5%Ni steel(ASTM A203 Gr. D,E) used for pressure vessels, storage tanks.
- Characteristics on Usage
-
- - W 8016C2 is an all positions extra low hydrogen type electrode for 3.5% Ni steel be used at low temperature. (lowest -100℃)
- - Good toughness of all-weld metal at low temperature.
- Notes on Usage
-
- - Preheat at 50~100℃ and postheat at 600~620℃. The preheat temperature varies in accordance with the plate thickness and the kind of steels.
- - Dry the electrodes at 350~400℃ for about one hour before use.
- - Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting.
- - Keep the arc as short as possible.
