- Applications
- WT-115 is designed for welding of 760MPa high tensile steel with outstanding mechanical properties.
Typical applications include low alloy steel, quenched and tempered high strength steels.
- Characteristics on Usage
-
- - It is a fully basic type flux cored wire for flat and horizontal position welding.
- - It provides smooth arc, low spatter levels, good weldability and good bead appearance.
- Notes on Usage
-
- - Proper preheating(50~150℃) and interpass temperature must be used in order to release diffusible hydrogen which may cause cracking in weld metal when electrodes are used for medium and heavy plates.
- - Gas flow rate is proper 20~25ℓ/min.
- - Shielding gas should be used Ar+20~25%CO2.
