Characteristics

YAWATA BT-52 is a rutile-cellulosic type electrode for a wide variety of mild steel fabri- cation and assembly application. Ideally suited for welding in the vertical-down position where it produces slightly concave welds merging smoothly into the base metal without any undercutting. Due to its excellent all positions operability and weld pool control, it is prefer- ably used for welding sheet metal containers, storage vessels, and oil tanks. In assembly work, it is possible to apply the same current setting in all positions. The slag comes off very easily as in most cases self-releasing. Welding bead appearance is smooth with fine ripple formation. Also use with welding transformers having a low O.C.V. (42V).
