Laser Welding Machine for Home Appliance, Automobile
CNC machinery is widely viewed as a hands on craft that employs the use of many types of saws, drills, and Cnc Routers and more but the use of CNC technology has made it possible to have all these jobs completed with great speed and precision, CNC Routers has wood cutting machine function,cnc machine milling function and cnc machinery engraving function. The quality and repeatability of the cuts that can be achieved using a CNC Routers is hard to ignore. Intricate wood carvings have long been a standard that has set custom jobs apart from others.

Note: After welding of stainless steel material ,welding seam the mechanics indexes are reaching or higher than the parent material properties, and the weld forming looks good, no macroscopic defects porosity, cracks appear 
The advantage of laser welding
(1) can reduce the amount of heat input to the minimum. The range of heat affected zone is small, and the deformation caused by heat transfer is also the lowest.
(2) the welding process parameters of 32mm thick plate and single channel welding have been certified, which can reduce the time required for heavy plate welding and even avoid the use of filler metal.
(3) there is no need to use electrodes, no electrode pollution or damage concerns. And because it does not belong to the contact type welding process, the loss and deformation of the machines and tools can be minimized.
(4) laser beam focusing, easy alignment and by optical instrument guide, can be placed in the appropriate distance from the workpiece, and can guide in the equipment or the obstacles around the work piece, and other welding rules can not play due to the limited space.
(5) the workpiece can be placed in enclosed space (controlled by vacuum or internal gas environment).
(6) the laser beam can be focused in a small area and can be welded with small and close spaced components.
