Enhanced FabCO Triple 7 Wire Offers Expanded Mechanical Properties

Building on a proven formulation, Hobart is offering its FabCO® Triple 7 gas-shielded flux-cored wire with expanded mechanical properties. In addition to the American Welding Society (AWS) E71T-1 C/M H8 classification the wire previous held, it now also meets the requirements for an AWS E71T-9 C/M H8 classification. Being able to address the demands of T-9 applications makes Triple 7 ideal for achieving versatility in manufacturing, construction, fabrication, ship, railcar and structural steel applications.

“We’re excited to offer this enhanced Triple 7 wire to our customers,” says Tim Hensley, product manager, Hobart. “The wire offers greater flexibility for their applications, along with high weld quality to help them improve productivity and reduce costs.”

Users can continue to expect the consistent performance Triple 7 wire is known for as a T-1 product, while gaining the opportunity to address T-9 applications without extra inventory. The T-9 designation provides greater impact strengths at low temperatures for critical jobs — 20 ft-lbs at -20 degrees Fahrenheit.

The new Triple 7 wire excels at welding with mixed gases (75% to 85% argon/CO2 balance) and is also usable with straight CO2. It has an American Bureau of Shipping (ABS) approval that certifies the wire meets the toughness requirements of 3Y classifications with both gases, and it is also approved for use in American Welding Society (AWS) D1.8 Demand Critical Seismic applications. In addition, the wire is Buy American compliant — manufactured with steel made and melted in the U.S. — for use welding government buildings, bridges and other structures under the Buy American requirements.

A fast-freezing slag and spray-like arc provide excellent weld pool control when welding out of position, allowing even less skilled welders to create flat, consistent welds. The slag is easily removed to simplify interpass and post-weld cleaning, and it reduces the risk of slag inclusions and the associated rework.

To further reduce rework, Triple 7 features an H8 designation that provides a weld deposit with less than 8 ml of hydrogen per 100 g of weldment to minimize the risk of cracking. Users can spend more time welding and increasing productivity instead of addressing post-weld repairs. Low spatter levels reduce the time and cost of post-weld cleanup.

Hobart is offering the Triple 7 wire in .045, .052 and 1/16 diameters in packages ranging from 15-lb. spools to 600-lb. X-Pak drums.
