Reusing waterjet cutting abrasive: Recycling systems recover used garnet, but are they worth worth the upfront cost?For shops that cut using a waterjet machine, the abrasive in the pressurized stream of water, which allows the system to cut away metal, is a significant capital investment. Because of recent technology developments, a fabricator now can recycle the abrasive material and use it several times. But before a shop invests in this type of equipment, it should first consider the types of abrasive material that are available, as well as how the recycling technology works.

Metalfab: All that glitters is metalLights. Camera. Fabricate?! You get home from work after fabricating all day, kick back with a cool one, and turn on the tube just to see more metal fabrication, on-screen, as entertainment. If it's not "American Chopper" or "Monster Garage," it's "Biker Build-Off," "Monster House" or "American Hot Rod." What's the fascination with fabrication? Do shows like these put a new spin on the image of metal forming and fabricating? Have they inspired younger generations to consider metal fabricating as a profession? Why have TV producers zoned in on these types of shows?

(Un) memorable fabrication: Oceaneering fabricates subtle creations in high-profile structural projectsOceaneering's structural fab operation has built "dark ride" vehicles for theme parks around the world. It has custom-fabricated and erected aluminum components for a mammoth advertisement overlooking Times Square. It has welded a structural mount that holds up the recovered World Trade Center antenna, now on display at the Newseum in Washington, D.C. And it has fabricated and erected duplex stainless steel bridges over killer whale pools at the San Diego and Orlando SeaWorld® parks. That's quite a portfolio of jobs, and all of them quietly have gotten their start at a structural fabrication facility on the outskirts of Baltimore.
