 The laser  composite cleaning principle is mainly through the semiconductor continuous laser as a heat conduction output, so that the attachment to be cleaned to absorb energy to produce gasification, plasma cloud, and the formation of thermal expansion pressure between the metal material and the attachment, reducing the interlayer bonding force between the two. When the pulsed laser outputs a high-energy pulsed laser beam, the vibration shock wave generated will make the adhesives with weak bonding force directly detach from the metal surface, thus realizing rapid laser cleaning. The applications of this technology cover ships, automobile repair, rubber molds, high-end machine tools, railroads, and environmental protection. Resins, paints, oils, stains, dirt, rust, coatings, plating, and oxidized layers can be removed. The advantages of laser composite cleaning technology are not only the superposition of two lasers, focusing on the utilization of energy is far greater than ...

  On the relationship between the four, many people can not, including a part of the equipment company engineers, many are waiting until the equipment problems to ask me, and customers to explain the relationship between the four a few hundred times, I think I need to spend a little time writing these out, and later when you ask, I will send this article directly to everyone. 1.  L aser outgoing light (Output beam diameter), this should be good to understand, it is from the laser output spot how big. This beam is generally collimated light, note that I said collimated light, not that parallel light, many people think that the light from the laser is parallel light. We often say that the laser's outgoing beam is a few millimeters, let's say the coherent CO2 C30A laser's outgoing light is generally 1.8 ± 0.2mm, and pulsed fiber laser outgoing light is generally 7mm, these are said to be the size of the laser's outgoing light. The continuous fiber laser out of the light is...

  Recently, the UK-based Welding Institute (TWI) is planning to launch a joint welding industry project that will benchmark handheld laser welding against existing manual arc welding processes. Specifically, the project will examine the quality, productivity, cost, health, and safety aspects of handheld laser welding, covering a wide range of materials and joint configurations.   Today, there is a growing interest in handheld laser welding applications in the welding industry. In recent years, suppliers such as IPG Photonics , Oree, Lightwise Laser, and New Day Laser have introduced compact, handheld laser welding systems with power ratings up to 3kW. These laser welding systems offer a number of advantages: low operating costs; minimal setup requirements; ease of use; efficient, fast, and flexible processing in challenging space environments; minimal consumables and post-processing requirements; and, most importantly, high-quality welds in similar and dissimilar materials of...

L aser welding Laser welding has many advantages such as deep melting, fast speed, small deformation, etc., which can greatly improve the safety of power batteries. Laser welding is not demanding on the welding environment, has high power density, is not affected by the magnetic field, is not limited to conductive materials, does not require vacuum working conditions and the welding process does not produce X-rays other advantages, are widely used in new energy vehicles and power battery manufacturing field. Laser welding technology can greatly improve the processing efficiency of power batteries, and welding precision, to ensure safety, reliability, and consistency, reduce costs, and extend service life.   In the production of power batteries using laser welding in the cell assembly and battery PACK link.   1.  Cell assembly section-middle section: the laser welding process is used in the shell, top cover, sealing nails, lugs, and other welding links 2. The core  a...
