To further reduce rework, Triple 7 features an H8 designation, meaning it deposits less than eight ml of hydrogen per 100 g of weldment, minimizing the risk of cracking. Click image to enlargeHobart is now offering a new 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 now also meets the requirements for an AWS E71T-9 C/M H8 classification.

Addressing the demands of these new applications makes Triple 7 ideal for versatility in manufacturing, construction, fabrication, ship, railcar and structural steel applications.

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 per cent to 85 per cent argon/CO2 balance) as well as 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 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 associated rework.

To further reduce rework, Triple 7 features an H8 designation, meaning it deposits less than eight ml of hydrogen per 100 g of weldment, minimizing the risk of cracking.

Users can spend more time welding 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.
