The main advantages of laser welding machine are as follows:

(1) The laser welding machine can reduce the heat input to the minimum required amount, 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 plate thickness single pass welding have passed the verification, which can reduce the time required for thick plate welding and even save 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 deformation of the machine tool 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 tools or obstacles around the workpiece. Other welding rules are affected by

Unable to play due to the above-mentioned space limitations.

(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 can weld small and closely spaced parts.

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

(8) It is easy to automate high-speed welding, and it can also be controlled by digital or computer.

(9) When welding thin materials or thin-diameter wires, there is no trouble of melting back like arc welding.

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