UV 306 is an agglomerated aluminate-rutile flux submerged arc welding of unalloyed steel grades. It is recommended for general-purpose applications and light steel constructions. It is suited for direct and alternating current. It can be used for single- and multi-wire welding with high welding speed using the two-run technique as well as for fillet welding. Mainly for single pass welds on thin plates (or a few subsequent passes). Very good slag removability and nice bead appearance. This flux has also been available on the market as BÖHLER BB 306.
