Therefore, In order to provide high contact pressure enough to conduct solid welding for the split AA7075 materials in welding chamber, the specific die cavity design has been finished.
Therefore, multiple dies are produced to meet the standards of the extrusion process, and die cost is increased greatly due to waste of materials, manpower and time.

Fig. 1 FDY-1.2 portable wind erosion wind tunnel Filling materials of subgrade model chooses the Aeolian sandy soil that was taken from the heartland of Hobq desert in Ordos altiplano and under the surface soil depth for 3m-5m.
Subgrade slope is eroded and filling materials of subgrade will be changed in influence of wind-sand flow intensity, blowing time, soil property etc.
l The blowing time are selected 20min and 40min, and analyzed pore changes of filler materials under different blowing time.

In addition, this material has good electrical stability and properties.
This material is also the basis for several high-temperature superconductors and GMR (giant magneto resistance) materials.
Preparation of a solar single-slope distillation apparatus The activity begins with preparing the necessary tools and materials and coating the bottom of the basin with paint that has been mixed with copper (II) oxide (CuO). 2.

Design and Testing of the Copper Pipe and Aluminum Pipe Welding Control System Zhang Yue1, a, Li Qidong2, Sun Taili2 and Zhang Xichuan2, b 1 School of Mechanical Engineering, Shenyang University of Technology, Shenyang China 2 Schoolof Material Science and Engineering, Shenyang University of Technology, China a zhangyue80@yeah.net, bzhangxichuan@126.com Keywords: copper pipe, aluminum pipe, weld, control, PLC Abstract.
But the substitute aluminum pipe for copper pipe is only partial rather than entire, due to the difficult of aluminum welding with other metal materials.
