1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 3 GA-120 RUTILE IRON POWDER ELECTRODE FOR ALL POSITIONAL FILLET WELDING INCLUDING VERTICAL DOWN WELDING DATA SHEET NO. 4 SPECIFICATION AWS A5.1 BS EN ISO 2560-B CLASSIFICATION E7014 E4914 PRODUCT DESCRIPTION A balanced rutile, iron powder, cellulose flux formulation that contains the necessary alloying elements that enables increased metal recovery to be balanced with a quick freezing slag. The flux is extruded onto a mild steel core wire with a blend of silicates that ensures coating strength and stability. WELDING FEATURES OF THE ELECTRODE The arc is stable and smooth both in AC and DC, spatter is negligible. Initial arc strike and re-strike are instant. Slag detachability is excellent and the weld is smooth and evenly rippled. As metal recovery is some 120% with respect to core wire weight, welding efficiency is increased. Fillet welds made in the flat and vertical down position are of a slightly concave appearance. APPLICATIONS AND MATERIALS TO BE WELDED All positional welding including vertical down. Fillet welds of the following materials : Mild and medium carbon-manganese steels up to 15mm thick with a UTS of 500 N/mm 2 max. Typical grades : BS 1449 plate and sheet, BS 4360 grades 43A and 43C, Lloyds A & D ship steel BS 4360 grade 50B Lloyds grades AH and DH, BS 3059 and BS 3601 grade 320-410 API 5L A-B and X42.
