Friction Stir Welding

Friction Stir Welding

MTI is dedicated itself to the research and application of friction stir welding (FSW) technology and has fulfilled dozens of the national key projects of the cutting-edge research on friction stir welding technology. Many core breakthroughs on the friction stir welding of the metals, including Al alloy, Mg alloy, Cu alloy and Ti alloy, have been made and mastered. In terms of FSW, MTI is the first unit in China establishing the aeronautical standards, such as the standards of “Process of friction stir welding for aluminum alloy aero-structural components” and “Friction Stir Welding Equipments”. Many innovative methods of FSW, for example friction stir spot welding, bobbin friction stir welding, stationary shoulder friction stir welding, have been well developed by MTI and applied to the industry.
There are 14 authorized patents owned by MTI in FSW area. In addition to that, 15 awards have been granted by Ministry of industry and information technology of China, China Federation of machinery industry, and AVIC group.

Fields of Application:
Subway train body joining, car hub welding, large scale flat/curved Al alloy welding
