Mechanized plasma cutting for HVAC applications: How equipment has progressed and what it offers today's fabricatorsJust 20 years ago most heating, ventilation, and air-conditioning (HVAC) ductwork was cut by hand with snips and shears. Cutting out HVAC fittings was slow and labor-intensive. It took an experienced tinsmith with strong hands to slice through galvanized steel all day. It took even more skill to get the cuts and bends just right to coax flat panels of sheet metal into precise 3-D forms.

Part feature developments in hydroforming products: Hydroforming continues to make automotive inroadsTube hydroforming technology continues to develop in ways that improve part utility, economy, or process robustness. Auto parts that have recently been produced by hydroforming include roof rails, radiator enclosures, a front-end structural module, and roof rails.

KNOWLEDGE: The key to welding productivity?: Study's findings have different meanings across manufacturing sectorsIn the year 2000 manufacturing, construction, and mining industries had $34.1 billion worth of welding-related expenses. At the same time more than a half million people in the U.S. had welding-related jobs -- and that's not counting self-employed and nonproduction welders.

New bends in the roll: Roll bending trendsAs more commercial buildings are designed with larger open spaces, the beam spans grow longer, and the beams must be bigger and heavier. This requires ever-larger section bending rolls to accommodate this demand. In addition, the trend toward the use of higher strength steels has taxed the capabilities of plate roll bending equipment. These changes and other emerging demands have driven the trend toward the use of CNCs, inline material handling, and larger angle bending rolls.
