SMOOTHCOR® 70C-6M

Smoothcor 70C-6M is a carbon steel, composite metal cored electrode for gas shielded arc welding. This electrode is intended for single and multiple-pass welding of carbon and certain low alloy steels, where a minimum tensile strength of 70,000 psi is required in the deposited weld metal. Recommended shielding gases are mixtures of Argon/CO2, with a minimum of 75% Argon, and Argon/O2, with a minimum of 95% argon.

SMOOTHCOR® 70T-1

Smoothcor 70T-1 is an E70T-1C electrode with a unique slag system which allows multiple weld beads to be stacked in a horizontal fillet with a minimum of "roll" or convexity. A carbon steel electrode intended for single and multiple pass welding in flat and horizontal fillet positions, Smoothcor 70T-1 is designed for use with carbon dioxide gas shielding. This is an excellent electrode for welding plates such as ASTM A36, A285, A515 and A516.
