Special exposition of innovative materials and technologies IMTECH: Belarusian National Technical University presents technology of laser welding of metals

Within 20th international exhibition TechInniProm.

Directions to the venue:joint booth “Ministry of education of Belarus”.

Laser welding is designed for welding homogeneous and dissimilar metals, butt welding of metal sheets of sufficiently large thickness in one pass, welding in hard-to-reach places and different spatial positions.

As opposed to traditional methods, laser welding has the following advantages due to the concentration of high power density in the laser beam:

  • High process productivity, characteristic welding speeds can reach 200-400 m / h, and when using laser arc technology (hybrid) technology – up to 2000 m / h;

  • The possibility of welding dissimilar metals. The ability to weld butt-off metal sheets of a sufficiently large thickness in one pass. The small width of the zone of thermal influence and the low level of deformation are approximately 3-5 times lower than in arc welding;

  • The possibility of welding in hard-to-reach places and different spatial positions. Good controllability and flexibility of the process, the possibility of full automation.
