Applications
All position welding of building, shipbuilding, bridges, machinery and vehicles.
Characteristics on Usage
SF-71 is a titania type flux cored wire for all position welding with CO??. Compared with solid wire, spatter loss is low, bead appearance is beautiful and arc is soft with good stability. Slag covering is uniform with good removal.
Notes on Usage
1. 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.
2. One-side welding defects such as hot cracking may occur with wrong welding parameter such as high welding speed.
3. Use 100% CO₂ gas.
