Solder the research current situation that the laser beam welding in the technology receives a technology and application

Laser solders to already was paid close attention to gradually by people, laser beam welding receives a technology to have high accuracy, high quality, low be out of shape, high rate and efficient characteristic. After 1970, wait as metallic aluminium solder corporeal development is successful, laser beam welding receives a technology to also get popularize and applied in other sphere. Be in especially manufacturing industry, metallurgy course of study and application of biology medicine respect are relatively wide. Later, as the development of space technology, laser beam welding receives a technology to be applied to spaceflight domain gradually. 1 solder domestic and internationally the 　 of research current situation that the laser beam welding in the technology receives a technology 1.

At present foreign laser beam welding receives the research current situation that 1 abroad laser beam welding receives a technology the technology is more mature already, US-led the development state of affairs that the developed country pays attention to laser beam welding to receive a technology very much. Among the development plan that accepts laser beam welding the technology to include a country, devoted and many capital is used at what laser beam welding receives technical research and personnel to groom. Expand the dominant position that traditional industry also notes in the process, accomplish laser beam welding to accept technology and couple of traditional industry posture. Because development is earlier, at present the laser beam welding of the developed country receives a technology to be put in a lot of advantages, basically have, heat affects area minimum, and solder the phenomenon that fire damage does not have in the process, solder speed wants fast 10-100 than solder of general bake in a pan times. Solder contact is dinky, the prevented foreign matter pollution of the oldest rate and corrode degree, in addition, the crack resistance that solder nods can be very tall also. 1.

The home of research current situation that 3 home laser beam welding receives a technology solders because the technology starts later, progress is relatively slow also. In recent years, as a result of the need of the requirement of policy and environmental protection, laser technology just is applied extensively gradually. The research that solders to laser basically also is in what laser beam welding receives to form mechanism centrally, detect, analysis, control. A few colleges also develop the relevant course that laser beam welding receives gradually, the weldability that exceeds granule steel through the analysis for instance reachs the characteristic that laser beam welding receives, undertook 400MPa and 800MPa are planted the laser beam welding that exceeds fine grain steel receives a trial. The research that at present home accepts solder sex respect to the laser beam welding of high strenth still exists the place of a lot of inadequacy, lack a lot of relevant data, still need to groom more professional have thorough research. 2 solder the application that the laser beam welding in the technology receives a technology matures gradually as what laser beam welding receives a technology, its apply a domain to also expand ceaselessly. But the cost that receives facility as a result of laser beam welding and upkeep costs are higher, besides the industry that large quantities of a few quantities are produced or dimensions spare parts solders, laser beam welding receives a technology to apply rarely. Euramerican laser beam welding receives a technology to basically apply at the metal to machine course of study and automobile manufacturing industry, and the laser beam welding of Asian area receives the application with more technology to be mixed at semiconductor industry electric equipment industry. 2.

The application of 1 manufacturing industry is in abroad, in receiving a technology to be made in the car, solder uses laser very extensive, grow in order to compare high rate. Japan developed the maintenance of canaliculus of generator of the vapour in using YAG laser beam welding at nuclear reactor successfully first on the world; Laser beam welding receives a technology more general also in shipbuilding, the tradition solders craft is out of shape after medium solder is the main problem that shipbuilding industry faces, and because have solder postheat to affect an area,laser beam welding is received small, fire damage the characteristic with the can tall crack resistance after small, solder, solder hind was not out of shape apparently basically; Because use laser beam welding to receive, the weight of hull was reduced on certain level, very main effect was produced in shipbuilding industry. 2.

The application of 2 metallurgy industry shows nowadays, more and more pulverous metallurgy material move toward the market, the join problem of it and other part is shown gradually, make the application of pulverous metallurgy is restricted. And because combine strength,laser beam welding receives a technology low, solder to be spent gently tall and very good high temperature resistant the development open up that the gender is pulverous metallurgy material new way. 2.

The important economy origin that the applied auto industry of 3 auto industry regards a developed country as is the stress that each country studies all the time. Laser beam welding is received automobile body weight also was reduced greatly while the technology is increasing automobile body strength, reduced the manufacturing cost of the car. At present laser beam welding receives a technology to be in a lot of in in high-grade car use extensively already. 2.

The application of 4 electrons industry receives a technology as a result of laser beam welding soldering the to machinery injury in the process degree lesser and can avoid mostly, special the requirement that accords with electronic industry. Area of the high accuracy of laser technology, free from contamination, hot influence is small wait for an advantage to also make laser beam welding receives a technology to receive wide application in electronic industry. Current, laser beam welding receives a technology to had been applied gradually in electronic industry, for example, a lot of businessmen all use laser beam welding to receive craft to produce heavy sensor. But the principle respect such as plating still is studying report of laser melt, laser in the center. 2.

The applied 　 of 5 biology medicine after 1970, the laser beam welding that organizes about biology is received begin to appear, basically apply at blood-vessel and oviduct solder. Receive advantage to be discovered by researcher gradually as laser beam welding, the laser that all sorts of biology organize solders to get popularizing gradually. Laser solders to appear in biology medicine go out to solder differently advantage. Basically have, rate of operation place be identical is rapid. And react without the eyewinker in heal process, the organization after repair can according to original growth characteristic a future life grows. Researcher also solders in welder of further research laser the application in biology medicine domain. 2.

The application of 6 aerospace domain is US-led developed country in 20 centuries laser beam welding of the experience at the beginning of 70 time receives the technical application in aerospace domain. They groomed professional researcher, to spaceflight industry all sorts of medium container reach lightweight structure project approving, began be as long as 7 years reinforce of old laser beam welding uses research. New research achievement replaced original riveting to encourage one, increased the strength of airframe, reduced the weight of airframe. Our country receives a technology in the laser beam welding of aerospace domain also is more advanced, all sorts of alloy that in beginning pair of spaceflight domains, use undertake laser beam welding accepts technical research, obtained very good positive result, and already threw gradually use. As a result of,laser beam welding is received very tall precision and dependability, the dominant position that in making its apply in this domain, shows is apparently strong at other method solder technology. 2.

The applied abroad in 7 plastic treatment solders to had been in banner level to the laser in plastic treatment, and our country still is in research to develop level. Laser beam welding receives the merit with little fire damage to make its are highlighted in the advantage of plastic treatment respect. Solder the material that beam of light stimulates to be able to pass disparate arrangement of ideas mostly in the process, and conduct harvest be suctioned more easily to be weld zone region through heat. The laser beam welding in plastic treatment receives the welder that compares a tradition art contaminative degree is smaller, quality is better, the application that also receives a technology for laser beam welding offerred more capacious prospect. After 21 centuries of 3 epilogue 　 , receive a technology as laser beam welding high temperature resistant, fire damage small, crack resistance can be good wait for an advantage to be shown gradually, the research territory that laser beam welding receives a technology also will more and more extensive. Researcher to soldering the laser beam welding in the technology receives research to also pursue advance gradually stage in practice. Laser beam welding receives a technology to develop at present, already had replace a tradition to solder gradually technical trend. CNC Milling
