Suzhou laser welding machine in general need to pay attention to what?

Suzhou laser welding machine uses high-energy laser pulse to heat the material locally in a small area. The energy of laser radiation is transferred to the internal diffusion of the material through heat transfer, and the material is melted to form a specific molten pool. Laser welding machine is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, overlap welding, seal welding, etc., with high depth width ratio, small weld width, small heat affected zone, small deformation, fast welding speed, flat and beautiful weld, no treatment or simple treatment after welding, high weld quality, no porosity, and accurate control, Small focus spot, high positioning accuracy, easy to realize automation.

Suzhou laser welding machine generally needs to pay attention to the following points:

1) In order to ensure that the laser is always in normal working condition, after two weeks of continuous operation or when it is out of service for a period of time, the components in the optical path such as YAG rod, dielectric diaphragm and lens protection glass should be checked before starting the laser, so as to ensure that there are no abnormal phenomena such as dust pollution and mildew in each optical component. If there are any above phenomena, they should be handled in time, Ensure that the optical components will not be damaged under the strong laser irradiation.

2) The purity of cooling water is the key to ensure the laser output efficiency and the lifetime of the laser concentrator. The conductivity of the internal circulating water should be checked once a week in use. Observe the color change of ion exchange column in the cooling system at any time. Once the color of resin in the exchange column turns dark brown or even black, replace the resin immediately. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process belongs to heat conduction type, that is, the surface heat is heated by laser radiation, and the surface heat is guided to internal diffusion through heat transfer. By controlling the parameters of laser pulse width, energy, peak power and repetition frequency, the workpiece is melted to form a specific molten pool. Because of its unique advantages, it has been successfully used in precision welding of micro and small parts.
