JOHNSTOWN, Pa., Jan. 28, 2011 /PRNewswire/ -- A Concurrent Technologies Corporation (CTC) mechanical engineer has received an international award for his work in friction stir welding (FSW). Kevin Colligan, a CTC advisor engineer, leads many of the company's efforts in FSW. He has published several technical papers and holds patents in developing FSW for practical applications. FSW is a solid state process that joins two pieces of metal with the use of a rotating pin that stirs the...

NEW ORLEANS, June 15 /PRNewswire/ -- The Orion crew exploration vehicle took shape as the two halves of the crew module were fused together at NASA's Michoud Assembly Facility in New Orleans, La. The Lockheed Martin Orion team welded the forward cone assembly to the aft barrel assembly using the next generation friction stir weld process. The 445-inch long weld is the longest such weld of its kind and will ensure optimal structural integrity for the harsh environments of space flight....

NASA has partnered with Lockheed Martin Space Systems in Denver, Colo., and MT Aerospace in Augsburg, Germany, to successfully manufacture the first full-scale friction stir welded and spun formed tank dome designed for use in large liquid propellant tanks. The NASA and Lockheed Martin team traveled to Germany to witness the first successful aerospace application of two separate manufacturing processes: friction stir welding, a solid-state joining process, and spin forming, a metal working...

Using a metal joining technique called friction stir welding, the Ares Projects team at the Marshall Center has completed welding the first liquid hydrogen tank dome being developed to define manufacturing processes for the upper stage of the Ares I -- the rocket that will launch explorers to the moon, Mars and beyond in coming decades. The innovative welding process produces high-strength welds that are uniformly joined together -- a vital requirement for next-generation launch vehicles and...

By Chen, Y C Nakata, K Friction stir lap joints of AC4C Al alloy (top sheet) and steel (zinc-coated steel, brushed finish steel, and mirror finish steel) were produced when the friction stir welding tool did not touch the lower steel surface. For zinc coat steel, the strength of joints could reach 97.7 pct of that of steel; for brushed finish steel, the strength was 63.2 pct of that of steel; for mirror finish steel, Al alloy and steel could not be welded. The effect of the surface state of...
