When industrial filter and filter housing manufacturer Filter Technology Inc. had one too many late and substandard shipments of steel components, it took matters into its own hands and started cutting pipe and making plate components using a band saw and machining centers. Then its staff went to FABTECH and saw a Soitaab plasma machine with a bed for flat parts and chucks for pipe.

The members of Battery G, 2nd Illinois Light Artillery had two cannons, an old school bus, and many miles to cover to stage mock battles. A team of Civil War re-enactors, they had discarded their previous bus and needed to transform their new bus. They enlisted the help of the staff and students at Blackhawk Technical College (BTC), Janesville, Wis.

If Richards Sheet Metal Works had taken the conventional path, it would have invested in a new flat-sheet cutting laser, especially considering its 5-kW workhorse was more than a decade old. But Richards isn’t a conventional metal fabricator. Today it has one of the largest tube cutting lasers in the country.

Eric Lundin provides an overview of many of the technologies displayed at the 2016 Tube Düsseldorf expo.
Alloy P91 has excellent high-temperature strength and creep resistance, making it a favored alloy for piping systems for power boilers and other applications that work at elevated temperatures and pressures. The conventional welding processes, gas tungsten arc welding and shielded metal arc welding, do a good job on P91, but modified gas metal arc welding (GMAW) processes and flux-cored arc welding (FCAW) have deposition rates three to four times faster.
