Cellulose Coated Electrode For Root Run Welding In Large Diameter Cross- Country Pipelines
C-11
CLASSIFICATION
AWS A5.1 E6010 | EN ISO 2560-A E 35 A C
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 potassium silicates which ensures coating strength.
WELDING FEATURES OF THE ELECTRODE
The electrode is suited for use on AC or DC+ 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 induced cracking.
APPLICATIONS AND MATERIALS TO BE WELDED
Cross country pipelines, on-site mild steel storage tanks, galvanized plates, boilers in following materials - mainly for 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 Grade X42, X46, X52, X56, X60.
May also be used in root runs for higher tensile steels in heavy equipment and building structures.
