Medical supplies, laser welded forming, beautiful appearance, firm, flat welding seam, no welding rod and chemicals are needed.
It is not affected by the magnetic field (arc welding and electron beam welding are easy), and can accurately align the element. Two kinds of metals with different physical properties (such as different resistances) can be welded. No vacuum or X-ray protection is required.
The heat input can be reduced 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.
The welding process parameters of 32mm plate thickness single pass welding have been verified, which can reduce the time required for thick plate welding and even save the use of filler metal.
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.
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 guided between tools or obstacles around the workpiece. Other welding methods cannot be used due to the above-mentioned space limitations. . The workpiece can be placed in a closed space (under vacuum or the internal gas environment under control). The laser beam can be focused on a small area, can weld small and closely spaced parts, can weld a wide range of materials, and can also join various heterogeneous materials. It is easy to automate high-speed welding and can also be controlled by a digital or computer. When welding thin materials or thin-diameter wires, it will not be as prone to reflow as arc welding.
