1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 3 D-03 RUTILE - LIME - LOW SILICIOUS FLUX COATED MILD STEEL ELECTRODE WITH EXCELLENT VERTICAL UP AND OVERHEAD WELDING CHARACTERISTICS DATA SHEET NO. 13 SPECIFICATION BS EN ISO 2560-B JIS Z 3211 CLASSIFICATION E4303 D4303 PRODUCT DESCRIPTION The flux is designed to produce a viscous slag with a wide solidification range which contains and refines the molten weld metal during positional welding. The flux is extruded onto a mild steel core wire with a blend of silicates that assures both strength of the coating while limiting moisture re-absorption. WELDING FEATURES OF THE ELECTRODE The electrode welds with a soft stable arc and produces bright evenly rippled weld seams. Slag detachability is excellent. In addition for the slag to control large vertical up and overhead weld beads, it also assists in the achievement of full penetration root runs. Again vertical up when joint access is only available from one side. APPLICATIONS AND MATERIALS TO BE WELDED All positional welding of structural steels of the following and related steel specifications: Mild and medium carbon-manganese steels up to 15mm thick (for several circumtances can be used up to 25mm thickness) with a UTS of 500N/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.
