OP 139

OP 139 is an agglomerated aluminate-basic type flux which has been designed for use with the high deposition rate submerged arc processes. Therefore OP 139 is perfectly suited for single or multi-layer welding in twin-wire, tandem or multi-wire processes both for longitudinal and circumferential welds. Even at high speeds the weld metal shows good wetting properties and smooth and straight weld toes. The slag detaches very easily even in narrow joint configurations and fillet welds.
