Technique of laser-TIG hybrid T-shape joint welding of titanium alloy Min Wang 1,a, Meiling Jiang 1,2,b, Qiang Wei1,c, Kanfeng Gu1,d 1Shenyang Institute of Automation, Shenyang, Liaoning Province, China 2Graduate School of the Chinese Academy of Sciences, Beijing, China amwang@sia.cn, bmljiang@sia.cn, cqwei@sia.cn, dkfgu@sia.cn Keywords: titanium alloy; T-joint; hybrid welding Abstract.
In the process laser beam can go through the level sheet and melt the legislative sheet to realize the penetration connection; by controlling the welding current, the arc at a certain angle with the level sheet and the laser beam provide the melting heat to produce the appropriate filler metal; the welded joints temperature Distribution and the pool profiles can be exactly controlled by the selection and configuration of laser hybrid welding parameters, so under the pool metals gravity, surface tension of molten material and the constraints of the jig equipment the welding foot can be achieved at the back bilateral side of T-shape joint.
In addition, as the laser spot acts on the back of TIG molten pool, the laser absorptivity of the material is extremely high to penetrate the work-piece with ease and a deeply penetrated weld seam is formed in the central line of the legislative board.

For example, spaceships can move long distances by using efficient electric engines, orbiting satellites can operate unlimited time periods without entry to Earth’s atmosphere, communication satellites can transfer a strong signal directly to customers, the International Space Station’s users can conduct many practical experiments and the global space industry can produce new materials.
As that is in science, the obstacles can slow, even stop, applications of these revolutionary innovations.

In class hours statistics, the result is lower than the minimum period of Liaoning university of traditional Chinese medicine, Changchun university of Chinese medicine is higher than the minimum period of and below the average hours of Heilongjiang university of Chinese medicine is the same as the period of highest. 2.3.2 Class Curriculum Comparison of Traditional Chinese Medicine Northeast 3 university of Chinese medicine of traditional Chinese medicine class curriculum, TCM nursing were set up, and the rest of the different subjects are also focus on specialized courses setting, Changchun university of Chinese medicine set up an introduction to Chinese traditional culture, the basic theory of TCM, TCM internal medicine nursing, set up a basic theory of TCM and Heilongjiang university of Chinese medicine, Chinese medicine diagnostics of traditional Chinese medicine (TCM), Chinese material medico, pharmacology, internal medicine, gynecology, pediatrics of traditional Chinese medicine
For national statistics of 20 colleges and universities of Chinese medicine, according to the results of 17 colleges and universities have opened a Chinese medicine basic course, 4 to open diagnostics of traditional Chinese medicine, 6 open Chinese material medico, 7 in pharmacology, 6 open acupuncture, 7 to open massage, opened a Chinese medicine nursing 14, 4 opened medical nursing.
Summary With the development of medical science and the increased awareness of traditional Chinese medicine, TCM nursing for its own "dialectical nursing" has become more suitable for needs in current society.
