- Applications
- WT-80CW is designed for welding of 590MPa weather-proof steel.
It is intended for use on low alloy weathering grade steels such as A588, A242, etc.
- Characteristics on Usage
-
- - It is a metal cored wire with superior pit resistance in welding of inorganic zinc-rich primer coated steel.
- - It is suitable for automation and high efficiency of horizontal fillet welding of ships, bridges, etc. because high speed welding is possible due to fast welding speed.
- Notes on Usage
-
- - Proper preheating (50~150°C) (122~302° F) and interpass temperature must be used in order to release 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.
- Sizes Available and Recommended Currents ( DC +)
