Most Advanced Laser Welding Equipment

China's most advanced maximum power HWF-160 ITER first wall of the laser welding station project recently passed inspection, and put into the International Thermonuclear Experimental Reactor (ITER) first wall half prototype certified member of the welding assembly. This marks the ITER enhance the thermal load of the first wall of the first station key manufacturing equipment has reached the design specifications and production requirements, will become the strong backing of the 2017 full-size prototypes of parts and subsequent production of mass-produced parts procurement package! At the same time, but also provide technical services for high-end manufacturing to other areas of nuclear power, aerospace and so on.

International Thermonuclear Experimental Reactor (ITER) program is currently the world's largest and most far-reaching international research cooperation projects. ITER is a device capable of producing large-scale superconducting tokamak nuclear fusion reaction, commonly known as "artificial sun." From a long-term basic needs of energy starting in May 2006, China ITER joint negotiating team with the EU, India, Japan, Korea, Russia and the United States signed the ITER project. The power can be penetrated 20 mm stainless steel plate, with arc hybrid welding with filler wire dedicated system, weld penetration can be further increased dramatically.The welding station by the West of nuclear College and Han's Laser AG was designed and built using the 16 kW IPG fiber 20000mw laser pen production, with six-axis KUKA robot welding station and two five-axis machines, equipped with automatic identification system welds, both achieve three-dimensional flexible welding, but also on the small radius of curvature and accurate identification, such as welding seam corner.

ITER first wall structure is complex, the individual products in the 1.4 × 1.0 × 0.3 (m) of space more than 800 welds, high penetration (15 mm) welding, deep groove bottom welding, small radius of curvature of the weld, welding deformation and weld spatter on the back of manufacturing technology are the key issues we face. And green laser pointer welding up strong, heat input is small, easy to control parameters, etc., through the tireless efforts FWIT team, these problems have been well resolved, especially in the technical aspects of the splash control seam on the back, we have come in the forefront of the world, and he accumulated a wealth of experience in the welding fixture design.
