1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 4 RD-16C2 LOW HYDROGEN ELECTRODE FOR WELDING LOW ALLOY FERRITIC STEELS SUBJECT TO SERVICE TEMPERATURES DOWN TO -80 º C DATA SHEET NO. 32 SPECIFICATION AWS A5.5 BS EN ISO 2560-B JIS Z 3241 CLASSIFICATION E8016-C2 E5516-N7 DL5016-6P3 PRODUCT DESCRIPTION The design emphasis of the chemically basic flux is engineered to ensure the optimum weld metal properties demanded by the specification are fully met. The basic flux containing the appropriate alloying elements but minimal iron powder, is extruded onto a high purity ferritic core wire and bound with a blend of silicates that ensure both coating strength and a coating resistant to subsequent moisture absorption . WELDING FEATURES OF THE ELECTRODE T he chemical nature of the flux together with its controlled coating factor allows the electrode to be used at relatively low amps. This factor together with the fairly fluid but quick freezing slag facilitate vertical up welding including controlled penetration root runs. Overall the arc is very stable, slag detachability is good, fillet welds are slightly convex and metal recovery is some 98% with respect to weight of the core wire. APPLICATIONS AND MATERIALS TO BE WELDED PLATES BS 1501-503, ASTM A203, A300, Grades D and E.
