Principles and Characteristics of Handheld Laser Welding 1. The principle of Handheld Laser Welding. Laser welding uses laser as welding heat source and robot as motion system. The special advantage of the laser heat source is that it has an extraordinary heating capacity and can concentrate a large amount of energy on a small point of action, so it has the characteristics of high energy density, concentrated heating, fast welding speed and small welding deformation. Realize the fast connection of thin plates. When the power density on the laser spot is large enough (>106 W/cm2), the metal is heated rapidly under the irradiation of the laser, and its surface temperature rises to the boiling point in a very short time, and the metal vaporizes. The metal vapor leaves the surface of the molten metal pool at a certain speed, generating an additional stress that reacts to the molten metal, causing it to dent downward, creating a small pit under the laser spot. As the heating process progresses, the laser can be directly injected into the bottom of the pit, forming a long and thin "small hole". When the recoil pressure of the metal vapor balances with the surface tension and gravity of the liquid metal, the small hole no longer goes deep. When the spot density is high, the small holes produced will penetrate the entire plate thickness to form… Read More »How much do you know about the principles and characteristics of laser welding?

Maintenance of Fiber Laser Welding First of all, it is particularly important to note that when inspecting the internal or external joint terminals of the Handheld Fiber Laser Welding Machine, the input power switch must be turned off before implementation. Perform regular inspections. For example, check whether the rotation of the cooling fan is smooth ,when the fiber laser welding machine handheld is energized; whether there is abnormal vibration, sound and smell; whether there is leakage of gas; whether the joints of the welding wire and the insulation wrap are loose or peeled; the welding cable and each Whether there is abnormal heat generation in the wiring part. Since the fiber welding machine is forced air-cooled, it is easy to suck in dust from the surrounding and accumulate in the machine. Therefore, we can regularly use clean and dry compressed air to blow away the dust inside the welding machine. Especially the parts such as transformers, reactor coils, gaps between coils and power semiconductors should be cleaned. Regularly check the wiring position of the power wiring. Whether the terminal screws on the input side, output side, etc., as well as the wiring part of the external wiring, the wiring part of the internal wiring, etc. are loose, remove the rust when it rusts to make the contact conductive. Long-term use of the fiber laser welding machine price will inevitably cause… Read More »Manual Operation And Maintenance Of Handheld Fiber Laser Welding
