In modern industrial manufacturing, laser processing technology is gradually replacing traditional mechanical, chemical, and heat treatment processes due to its non-contact, high-precision, and high-efficiency characteristics. Among these, laser marking, laser cleaning, and laser welding are the three most widely applied core processes, each addressing specific manufacturing pain points in different scenarios.
Laser Marking uses a high-energy-density laser beam to create permanent marks on material surfaces. Compared to traditional inkjet coding and mechanical engraving, laser marking offers the advantages of being consumable-free, permanent, and capable of achieving sub-micron-level precision. It is widely used for serial number engraving on electronic product housings, QR code traceability on automotive components, and identity marking on medical devices, serving as a critical link in achieving full product lifecycle management.
Laser Cleaning is an environmentally friendly surface treatment technology. By irradiating the workpiece surface with a high-energy laser beam, contaminants such as oil, rust, and coatings are instantly vaporized or stripped away, achieving thorough cleaning. Compared to traditional sandblasting and chemical cleaning, laser cleaning produces no secondary pollution, does not damage the base material, and allows precise control of cleaning depth, demonstrating immense potential in mold cleaning, cultural relic restoration, and pre-weld surface preparation.
Laser Welding utilizes a high-energy-density laser beam as a heat source to achieve precise joining of materials. Its narrow weld seam, small heat-affected zone, and low deformation make it especially suitable for welding thin-sheet materials and dissimilar metals. In the new energy vehicle sector, laser welding is extensively applied to tab welding of power batteries, body-in-white assembly welding, and stator welding of flat-wire motors, significantly enhancing battery safety and vehicle body lightweighting.
With continuous breakthroughs in core light source technologies such as fiber lasers and blue lasers, the processing efficiency and application scope of these three processes continue to expand, providing robust technical support for the intelligent upgrading of global manufacturing.
