Medium & High Tensile Steel Electrodes
SUPERLINK 88W
A low-hydrogen, iron-powder electrode designed for welding weathering steels (Cor-Ten type, ASTM A588, A242). Deposits weld metal with alloying elements (Cu, Cr, Ni) to match the atmospheric corrosion resistance of weathering steel base metals. Produces X-ray quality welds.

Welding procedure & parameters
DC+ (DCEP). All positions except VD. Re-dry 250°C–300°C/2 hrs. Preheat per base metal.
Typical applications
Bridges, highway structures, architectural exposed steelwork, utility poles, sign bridges, buildings using weathering steel (ASTM A588/A242/SPA-H) that rely on natural rusting for corrosion protection.
Storage & handling notes
Low-hydrogen type. Re-dry before use. Store dry.
