5、resent stage, the welding is widely used in connection of a variety of materials, and with the continuous development of high and new technology, the original traditional welding method is transformed into a laser beam welding and other advanced welding technology Can say, whether in the constructio
6、n industry, vehicles or machinery medical equipment, etc, leave the welding technology is not running1. And with the increasing communication with foreign, modern welding technology has the dissimilar materials of non-metallic materials connection technology, the surface and in the product design an
7、d production methods have a better innovation, can say, welding technology development prospects are very bright, the future of welding technology is filled with hope2.The development status of modern welding technology In recent years, economic impetus to the development of the manufacturing, weldi
8、ng technology also had great progress3, the efficiency of welding products also more and more high, now how to ensure the quality of products under the premise of realizing the automatic and intelligent welding has become an important task of welding industry Modern high and new technology such as i
9、ntelligent control technology in welding technology4, such as image processing and sensor technology, makes the modern welding technology with more relevant to the development of the trend of The Times5.Welding production automation and intelligent development Intelligent development of welding indu
10、stry is mainly embodied in the development of the intelligent robot welding6, welding automation level to a certain extent, can be understood as the development level of welding robot Is currently the most widely used welding robot is a type of teaching and reappearing, namely guided by artificial r
11、obot end executor (at the end of the structure of robot joint holder tool welding torch spray gun, etc.), or by manual operation guide mechanical simulation device, or use the teach box (connected to the control system of a hand-held device, to the robot programming or make movement) to make robot t
12、o complete the desired action, because of this kind of robot programming by real-time online teaching program7, and the robot itself from memory operations, it can constantly repeated This creates a welding robot automatic welding8.Welding efficiency at a high speed To achieve the further developmen
13、t of the welding industry, the need to optimize the current welding process, converting the traditional welding technology to high efficient high quality of the welding process at home and abroad9 and has also invested in the optimization of welding process more energy, today has been activation on
14、the welding process of multiple gas shielded welding process has achieved good results In the study of the welding speed also had great progress, now already can reach 1.8 m/min, greatly improve the efficiency of welding products10 And with the foreign in the digital welding power source and focus o
15、n advanced information processing technology, the Chinese market is gradually introducing relevant advanced technology products and digital welding power source has solved the original relatively rigid rigid control, to achieve flexible control of welding process and multifunctional integration11, a
16、nd the stability of the precision of welding process of welding system consistency of product Products have higher requirements in such aspects as the upgrade process12, can help to the development of modern welding technology has better, make welding technology to achieve high13.The optimization of
17、 welding quality assurance. For welding products, welding quality of the most important is14, if the welding quality is not very desirable, to the future life of the product is very limited, and the weld tracking technology to control the welding quality is critical In the seam tracking technology,
18、welding industry investment is more, also have a mature technology Such as advanced melting drop transition control nowadays due to the digital welding power source is introduced, and on the system USES the advanced electronic components, control of melting ice in a more handy, also do not lose on t
19、his aspect of the application to the foreign advanced level, this is very important part in the welding industry, is an important technology to ensure the quality of welding products.Welding technology development of modern advanced Modern technology with the exchange and sharing with foreign advanc
20、ed technology, has reached a high level, the following will use laser welding as an example in this paper, the advantages and the new progress of laser welding technology belongs to the part of fusion welding, it is based on laser beam energy, direct impact on the weld joint, the welding method to d
21、etermine welding position requirement is very high, need to be very accurate, need to make sure that welding position within the scope of the focused laser beam laser welding of maximum thickness of welding is limited, generally more than 19 mm penetration thickness of workpiece is not recommended f
22、or laser welding, for welding technology has great difficulties, not only for welding pieces of the product itself is not easy to have a better welding quality In addition, the laser welding of high reflectivity and high thermal conductivity welding15.Summary Under the condition of our country is st
23、ill dominant in the industrial industry, modern welding technology for industrial role is promote the development of self-evident Along with the development of economy and technology, more and more researchers and scientists to focus on the exploration on the perspective of new welding materials, it
24、 is for the present status of our current welding industry very desirable, is not deep contact area, if can in the new material of attention at home and abroad research achievements, this will be the welding field a revolution for decades.References1刘强.现代焊接技术发展的现状及前景J.科技致富向导，2012，（2）.2姚河清，陈亚政，孟庆芹.现代
