   The development of laser technology has driven the development of laser welding machines. In many industries, laser welding machines are used in many industries. Let's look at the laser cleaning methods for laser welding. The laser welding machine is a pulsed laser with a wavelength of 1064 nm generated by a laser. After being expanded, reflected and focused, the surface of the workpiece is radiated, and the surface heat is diffused to the inside through heat conduction. 

   The width, energy, peak power and repetition of the laser pulse are precisely controlled by digitization. Parameters such as frequency cause the workpiece to melt to form a specific molten pool, thereby achieving laser welding of the workpiece. In the introduction of the previous machine, it has been mentioned that there are three Si laser mirror and one focusing Si laser mirror on the engraving machine (the No. 1 Si laser mirror is located at the exit of the laser tube, that is, the upper left corner of the machine, and the No. 2 Si laser mirror is located at the left end of the beam. The laser mirror No. 3 is located at the top of the fixed portion of the laser head, and the focusing Si laser mirror is located in the adjustable barrel of the lower part of the laser head. The laser is reflected by these lenses, and is focused and emitted from the laser head. The lens is easily stained with dust or other contaminants, causing laser loss or lens damage. Do not remove the No. 1 and No. 2 lenses. Just wipe the lens with the cleaning solution carefully along the center of the lens. Edge rotary wipe. 

   The No. 3 lens and the focusing Si laser mirror need to be taken out from the frame, and wiped in the same way. After the wiping is completed, it can be put back as it is. The laser is used to seal the sensor metal casing is currently the most advanced processing method. The use of laser welding has the characteristics of beautiful and firm solder joints, small heat affected zone, high efficiency and low welding cost.
