What is a laser welding machine ? Laser welding is a type of welding machine. It is used in many industries because it is closely related to the development of technology. So what are the advantages of laser welding?
(1) The required amount of heat can be reduced to a minimum, the metallographic range of the heat affected zone is small, and the deformation caused by heat conduction is also the lowest.
(2) Welding process parameters for single-pass welding of 32mm plate thickness have passed the verification, which can reduce the time required for thick plate welding and even eliminate the use of filler metal.
(3) There is no need to use electrodes, and there is no concern about electrode contamination or damage. And because it is not a contact welding process, the wear and tear of the machine can be minimized.
(4) The laser beam is easy to focus, align and be guided by optical instruments. It can be placed at an appropriate distance from the workpiece, and can be re-guided between the tools or obstacles around the workpiece. Other welding laws are limited by the above space. And cannot play.
(5) The workpiece can be placed in a closed space (under vacuum or internal gas environment under control).
(6) The laser beam can be focused on a small area, and small and closely spaced parts can be welded.
(7) A wide range of materials can be welded, and various heterogeneous materials can also be joined to each other.
(8) It is easy to perform high-speed welding by automation, and it can also be controlled by digital or computer.
(9) When welding thin materials or small diameter wires, it will not be easy to be melted back like arc welding.
(10) It is not affected by the magnetic field (easy for arc welding and electron beam welding), and can accurately align the weldment.
(11) Two metals with different physical properties (such as different resistances) can be welded.
(12) No vacuum or X-ray protection is required.
(13) If through-hole welding is used, the bead depth-to-width ratio can reach 10: 1.
(14) The switching device can be used to transmit the laser beam to multiple workstations.
