The laser welding machine uses a high-intensity laser beam to radiate to the metal surface, locally heats the material in a small area, and melts the material to form a specific molten pool to
achieve the purpose of welding.
Laser welding features:
Lasers are considered an ideal heat source for welding and are recognized as high technology. Laser welding has the advantages of concentrated heating, less heat input, small deformation, and
fast welding speed; large weld depth ratio, flat weld, beautiful appearance, no need or simple treatment after welding, high weld quality, no pores; can be precisely controlled , The focusing
spot is small, the positioning accuracy is high, and it is easy to realize automation; it is not only suitable for conventional materials, but also especially suitable for insoluble metals and
heat-resistant alloys. Titanium alloys have dissimilar metals with large differences in thermophysical properties, workpieces with large differences in volume and thickness, and components near
the weld that are flammable, cracked and explosive when heated. Compared with vacuum electron beam welding, laser welding has the advantages of not generating X-rays, no vacuum chamber, and
unlimited workpiece volume. Laser welding can be used as a final process, and the weld is beautiful and beautiful, and in many cases the weld can be as strong as the base metal. Laser welding
can not only spot welding, but also continuous seam welding, stitch welding, sealing welding, etc., with high aspect ratio, small weld width, small heat affected zone and small deformation.
