Abstrac t. The development of economy makes the modern welding technology has made considerable progress, widely in different fields are related to industrial applications The article main to the present situation of the development of modern welding technology Present difficulties and future prospect of development has carried on the brief discussion and research, hope for the future of modern welding technology development as a reference.
Introduction
For the industrial development of the our country present 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 construction industry, vehicles or machinery medical equipment, etc, leave the welding technology is not running [1]. 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 and production methods have a better innovation, can say, welding technology development prospects are very bright, the future of welding technology is filled with hope[2].
The development status of modern welding technology
In recent years, economic impetus to the development of the manufacturing, welding technology also had great progress[3], 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 intelligent control technology in welding technology [4], such as image processing and sensor technology, makes the modern welding technology with more relevant to the development of the trend of The Times[5].
Welding production automation and intelligent development
Intelligent development of welding industry is mainly embodied in the development of the intelligent robot welding[6], 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 robot 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 to complete the desired action, because of this kind of robot programming by real-time online teaching program[7], and the robot itself from memory operations, it can constantly repeated This creates a welding robot automatic welding[8]. Welding efficiency at a high speed
To achieve the further development 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 abroad[9] and has also invested in the optimization of welding process more energy, today has been activation on 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 products[10] And with the foreign in the digital welding power source and focus on 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 integration [11], and the stability of the precision of welding process of welding system consistency of product Products have higher requirements in such aspects as the upgrade process [12], can help to the development of modern welding technology has better, make welding technology to achieve high[13].
The optimization of welding quality assurance.
For welding products, welding quality of the most important is[14], 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, 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 this 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 advanced 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 determine 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 for 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 welding[15].
Summary
Under the condition of our country is still 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 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.
