Agglomerated, aluminate-rutile, low basicity flux for Submerged Arc Welding. Top-class surface finish and excellent slag detachability. High welding speeds. For pressure vessels, general construction, automotive, beam fabrication, low requirement pipeline steels, etc. Fine grained version especially for membrane wall panel fabrication. For butt welds and especially for concave horizontal fillet welds. Suitable for single and multi wire procedures, for DC and AC. Due to high Si-alloying intended for a limited number of passes and plate thickness up to about 25 mm.
