Hobart Brothers offers its Tri-Mark® TM-770 gas-shielded flux-cored wire for use on high-volume carbon steel applications that require high-impact properties. Suitable for use on shipbuilding, offshore structural, and general fabrication applications, the wire meets the certifications of the American Bureau of Shipbuilding (ABS), Germanischer Loyd, and select military specifications.
The wire is rated at a tensile strength of 83,000 PSI and 79 ft.-lb. at sub-zero temperatures down to -40 degrees Fahrenheit (-40 degrees Celsius). Its smooth, stable, and soft arc creates virtually spatter-free welds to minimize post-weld cleanup time, the company says.
Engineered for single- and multiple-pass welding in all positions, the wire produces a flat weld bead profile, even in the vertical-up position, and is designed for use with mixed shielding gases (75-85 percent Argon/15-25 percent CO2). It comes in 0.035-, 0.045-, 0.052-, and 1/16-in. diameters.
