1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 3 C-10 CELLULOSE COATED ELECTRODE FOR VERTICAL DOWN WELDS IN LARGE DIAMETER CROSS-COUNTRY PIPELINES DATA SHEET NO. 1 SPECIFICATION AWS A5.1 BS EN ISO 2560-B CLASSIFICATION E6010 E4310 PRODUCT DESCRIPTION The electrode contains some 35% of organic materials which in the arc transform into a shielding gas and contributes to a concentrated deep penetrating arc with a fast-freezing slag. The flux is extruded onto a mild steel core wire using only sodium silicates which ensures coating strength. WELDING FEATURES OF THE ELECTRODE The electrode is suited for use on DC+ only and is ideal for full penetration root runs using a controlled root gap and root face and a stringer bead technique. Slight grinding of the stringer bead with wire brushes prevents lateral inclusions followed by a hot pass that particularly on high stressed and or high carbon steels promotes hydrogen diffusion and thus reduces the probability of hydrogen cracking. APPLICATIONS AND MATERIALS TO BE WELDED Cross country pipelines - on site storage tanks in following materials - mainly root pass: Mild Steels: St 360, C-St 510 C, St 34.2, St 37.2, St 46.2, St 37.3, St 46.3, St 52.3 . Pressure vessel steels: H1, H11, St 35 KKW, St 41 KKW. High strength steels: St52, St35.4, St45.4, St 52.4, StE210.7-StE415.7, StE290.7, TM-StE415.7TM, St35.8, St45.8. API 5LX: X42, X46, X52, X56, X60 . May also be used in root runs for higher tensile steels. WELD METAL ANALYSIS COMPOSITION % BY Wt.
