2、工程 2015 2015 年 06 06 月 26 26 日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 ro

3、bot itself from memory operations, it can constantly repeated This creates a welding robot automatic welding[8].Welding efficiency at a high speedTo achieve the further development of the welding industry, the need to op

4、timize 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

5、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

6、, 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 rele

7、vant 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 stab

8、ility 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 h

9、as 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 th

10、e 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 technolo

11、gy 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

12、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 de

13、velopment 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

14、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

15、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 thi

16、ckness 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 la
