Tensileweld Electrode – 1 lb Pack (Select Size From Options Above)

High-strength AC/DC welding electrode for difficult steels, dissimilar metals, and demanding repair applications.
Washington Alloy Tensileweld is a special-purpose electrode designed for applications where high strength, ductility, and porosity-free weld deposits are important. It is especially useful for welding dissimilar steels, high-carbon steels, tool and die steels, stainless steels, spring and coil steels, pressure vessel steels, aircraft steels, and applications where the exact alloy content of the base metal is unknown.

The weld deposit offers resistance to impact, abrasion, heat, and corrosion while maintaining a smooth, ductile, crack-resistant structure.

Package Information: This Arc-Zone listing is sold in 1 lb packs and is available in 3/32" or 1/8" electrode diameter.

Available Sizes

Select either 3/32" or 1/8" electrode diameter from the options above.

Recommended Welding Practices

Clean the work area before welding and bevel thick sections as required. Washington Alloy recommends a preheat of approximately 400°F for carbon and cast steels where appropriate.

• Use AC or DC reverse polarity (DC+).
• Maintain a short arc.
• Hold the electrode slightly inclined in the direction of travel.
• Use stringer beads.
• Peening is recommended for appropriate applications.

Note: The listed amperage and voltage ranges are typical flat-position parameters. Actual welding settings may vary with position, base material, joint design, equipment, and welding procedure.
