1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 3 C-10G CELLULOSE COATED ELECTRODE FOR PIPE WELDING DATA SHEET NO. 3B SPECIFICATION AWS A5.5 CLASSIFICATION E7010-G 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.
