OK Flux 10.70 is an agglomerated, basic flux for submerged arc welding. It is designed for welding joints with high dilution such as I-joints with one run from each side and fillet welds. Due to its high alloying of mainly Mn, it creates a weld metal with good toughness values in these joints. It can be used for single and multi-wire procedures and works equally well on DC and AC. On multi-pass welding the number of passes is limited and the plate thickness should not exceed approximately 25mm.
Non-alloyed wires such as OK Autrod 12.10 and OK Autrod 12.20 are the preferred ones to be matched with OK Flux 10.70. The main application area for OK Flux 10.70 is in shipbuilding. Here it is used preferably in the two-run, double-sided technique. However, it is also used in other market segments where joints with high dilution or several passes are welded. This is in the construction of pressure vessels, in the transport industries and general construction.
