- Applications
- WT-70C is designed for welding of 50kgf/mm² high tensile steel with outstanding mechanical properties.
- Characteristics on Usage
-
- - Typical applications include building, shipbuilding, bridges, machineries, vehicles, offshore structures and general fabrications.
- - It is a metal cored wire for all-position welding with Ar+20~25%CO2 shielding gas.
- 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.
- - One-side welding defects such as hot cracking may occur with wrong welding parameter such as high welding speed.
- - Shielding gas should be used Ar+20~25%CO2.
