浅谈铝合金激光焊接的前景展望
 

铝合金激光焊接最为引人重视的特点是其高效率,而要充分发挥这种高效率就要把它运用到大厚度深熔焊接中。因而,研讨和使用大功率激光器进行大厚度深熔焊接将是将来发展的必然趋势。

浅谈铝合金激光焊接的前景展望

 

大厚度深熔焊愈加突出了小孔景象及其对焊缝气孔的影响,因而小孔构成机理及其操控变得愈加主要,它必将变成将来学术界及工业界一起关心和研讨的热点问题。
 
  改进激光焊接进程的稳定性和焊缝成形、提高焊接质量是大家寻求的目标。因而,激光-电弧复合技术、填丝激光焊接、预置粉末激光焊接、双焦点技术以及光束整形等新技术将会得到进一步的完善和发展。
 
  别的,有人发如今CO2激光焊接熔池中存在几安培的固有电流,焊接区的外加磁场会影响熔池的流动状况以及光致等离子体的形状和稳定性。

因而,选用某种方式的磁场有也许改进铝合金激光焊接进程的稳定性和焊缝质量。所以,选用辅佐电流,经过其构成的电磁力操控熔池流动状况,从而改进焊接进程的稳定性,提高焊缝质量,也也许会遭到更多研讨者的重视。

 

The most important characteristic of laser welding of aluminum alloy is its high efficiency, and it is important to use it in the deep penetration welding process. Therefore, it is an inevitable trend to study and use high power laser for the future development of deep penetration welding. Large

thickness of deep penetration welding is becoming more and more highlighted the keyhole scene and its influence on weld porosity, and a small hole mechanism and control is becoming more and more important, it will become in the future of the hot issues in the academic and industrial attention and research.


Improve the stability of the laser welding process and welding process, improve the quality of welding is to seek the goal. Therefore, laser arc hybrid welding, laser welding, laser beam welding, double focus technology and beam shaping technology will be further improved and developed.


In addition, it is found that the current CO2 laser welding of the weld pool in the presence of a few ampere of current, the welding area of the external magnetic field will affect the flow of the molten pool and the shape and stability of the light induced plasma. Therefore, the magnetic field of a certain way may improve the stability of the laser welding process of aluminum alloy and the quality of the welding seam. Therefore, the selection of auxiliary current, through the

electromagnetic force to control the flow of molten pool, so as to improve the stability of the welding process, improve the quality of the weld, may also be more attention of researchers.
