Compared to the traditional manual welding, automatic laser welding has unparalleled advantages

(1) The required amount of heat can be reduced to the minimum, the metallographic change range of the heat affected zone is small, and the deformation caused by heat conduction is also the lowest.

(2) The welding process parameters of 32mm thick single-pass welding have been verified and qualified, which can reduce the time required for thick plate welding and even save the use of filler metal.

(3) no need to use the electrode, no electrode contamination or damage concerns. And because it does not belong to the contact welding process, the wear and deformation of the machine can be minimized.

(4) The laser beam is easy to focus, align and be guided by optical instruments, 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 cannot be played due to the above space limitations.

(5) The workpiece can be placed in a closed space (under vacuum or under control of the internal gas environment).

(6) The laser beam can be focused on a small area, and small and similarly spaced parts can be welded,

(7) a wide range of weldable materials, and various heterogeneous materials can also be joined to each other.

(8) easy to automate high-speed welding, can also be digital or computer control.

(9) When welding thin material or thin diameter wire, it will not be easy to melt back like arc welding.

(10) is not affected by the magnetic field (arc welding and electron beam welding is easy), can accurately align the weldment.

(11) can be welded different physical properties (such as different resistance) of two kinds of metal

(12) No vacuum or X-ray protection is required.

(13) If perforated welding is used, the depth-to-width ratio of the weld bead can reach 10:1.

(14) The device may be switched to transmit the laser beam to a plurality of workstations.
