1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 3 C-10Mo CELLULOSE COATED ELECTRODE FOR VERTICAL DOWN WELDS IN LARGE DIAMETER CROSS- COUNTRY PIPELINES DATA SHEET NO. 3 SPECIFICATION AWS A5.5 BS EN ISO 2560-B CLASSIFICATION E7010-A1 E4910-1M3 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 both full penetration root runs using a controlled root gap and root face and a stringer bead technique and the capping pass. 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 induced cracking.
