Manufacturing is the turbine runner runner's heart. Good quality turbine runner only possible good, good quality turbine runner was not good enough. To a good runner, design is essential, manufacturing is the key. For seven years the whole process of our wheel manufacturing, namely casting, machining single airfoil testing, assembly, welding, heat treatment and deformation control, weld nondestructive testing, import and export accurate measurement of the angle of placement, fine grinding shovel, split Runner on-site welding and after welding process constantly sum up self, learning advanced, gradually increase. Runner-chip is no longer left before the second allowance, air shaft crossed by three-dimensional computer-aided detection alternative model, GAOBAZHOU, Gangkouwan blade CNC machining, molding Xiaoguanzi blades, Ertan, large mixed gas shielded arc welding monastery runner, three-dimensional space large cross section of the weld ultrasonic flaw detection method, are a concrete manifestation of this increase.

The main results are:

Precision cutting and shaping the quality of Tepco Ertan volute and other suppliers than imports (l) of the volute;

(2) Tombs A517M spiral welding;

(3) Multiple cold forming spherical runner chamber and vanes inside and outside the ring;

(4) 90OMW nuclear turbine generator outer housing of the welding;

(5) hydrogen tungsten arc welding on thin and fittings commonly used;

(6) The narrow gap welding debugging and trial;

(7) The centralized development of brazing technology. IF developed a transportable welder, n-type hydropower magnetic coil terminals manufacturing process, 60oMw turbogenerator joint welding technology, widely used in low silver solder;

(8) runner, the rotor frame, frame, seat ring spot welding technology.
