- Applications
- WT-71T9CJ is designed for welding of 490MPa a low temperature steels.
It can be used in a variety of applications including railcar, automotive, machinery, shipbuilding, bridges, heavy equipment etc.
- Characteristics on Usage
-
- - It is a titania type of flux cored wire for all-position welding.
- - It provides smooth arc, low spatter levels, good weldability and good bead appearance.
- - Its design achieves low temperature impacts and can be used in semiautomatic and
automatic applications.
- 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.
- - One-side welding defects such as hot cracking may occur with wrong welding parameter such as high welding speed.
- - Gas flow rate is proper 20~25ml.
- - Shielding gas should be used 100% CO2.
- Sizes Available and Recommended Currents ( DC +)
