- Applications
- WT-110K4 is designed for welding of 760MPa high tensile steels.
It is intended for single and multiple pass welding of certain carbon and low alloy steels.
- Characteristics on Usage
-
- - WT-110K4 is a premium, composite metal cored wire, exhibiting superb welder appeal and outstanding mechanical properties.
- - There are many advantages in using composite metal cored, such as faster travel speeds, leading to increased productivity.
- - It is ideal for those applications where the slag residue and fume emissions of flux cored wire are unwanted.
- Notes on Usage
-
- - Proper preheating(50~150°C) 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.
- - The recommended shielding gas is argon-carbon dioxide mixtures within the range of 75% to 95% argon.
- Sizes Available and Recommended Currents ( DC +)
