Flux cored welding 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.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.
