Caution
① Dry at 300~350°C (572~662°F ) for 60 minutes before use.
② In the case of multi-layer welding of the thick plate, please set the conditions of first-layer welding in 500~550A, 26~30V, and 30~40cpm to prevent cracks and to remove slag.
③ Preheat to 50 to 100℃ depending on the thickness of the steel, and 100 to 200℃ Interpass Temperature is appropriate.
④ When restraint stress is high or welding a thick plate, preheat according to rules. - Purpose ① Single-layer and multi-layer welding for wind tower
-
Attribute
① Inert flux cause little change in the chemical composition of the weld metal, even during the changes in welding conditions, therefore it is suitable for single-layer welding in the construction of wind towers.
② Good impact value in multi-layer welding and Two-run welding
③ Good bead appearence, slag detachability and pit resistance
