Laser cleaning is a process in which the dirt, contaminants and impurities on the metal surface are removed or cleaned off by virtue of laser beam. Traditional industrial cleaning modes mostly use chemical catalyst and mechanical methods for cleaning. Today, with the increasing awareness of environmental protection and safety, the types of chemicals that can be used in industrial cleaning will become less and less.

The surface does not fade over time due to its high corrosion resistance and mechanical properties. Stainless steel is used in the decorative manufacturing industry because it has distinct color variations and other qualities depending on the angle of light. For instance, in a number of high-end clubs, public recreation areas, and other local decorations.

Regarding the development and application of lasers, CO2 lasers were produced and applied earlier and more often. As early as the late 1970s, CO2 lasers were directly imported from abroad for industrial processing and medical applications. Since the late 1980s, CO2 lasers have been widely introduced and used in the field of material processing.

During the use of the tube laser cutting machine, the metal tube to be processed needs to be transported to the worktable of the laser cutting machine, and then the laser cutting machine performs laser processing on the metal tube. At present, the feeding methods of tube laser cutting machine users mainly include manual handling, crane lifting and forklift forklift. These three methods have low degree of automation, require high labor and time costs, and have not maximized the production efficiency of the tube laser cutting machine.

When the spot of the focus laser is adjusted to the minimum, the initial effect is established by spot shooting, and the focal length is judged by the size of the spot effect. We only need to look for the minimum laser spot, then this position is the best processing focal length , And then start processing work.

The metal laser cutting machine will generate a large amount of heat when processing sheet metal. Under normal circumstances, the heat generated by cutting will diffuse along the cutting seam into the processed sheet metal and be sufficiently cooled. In the processing of small holes in the metal laser cutting machine, the outside of the hole can be sufficiently cooled, but the small hole inside the single hole is likely to cause over-burning, slagging, etc. As a consequence of the small space for heat diffusion and excessive heat energy. What’s more, in the cutting of thick sheets, the molten metal accumulated on the surface of the material and the accumulation of heat generated during the piercing will cause the auxiliary airflow to be turbulent and excessive heat input,resulting in overburning.

Many stainless steel items must be linked during the manufacturing process, which is normally achieved using argon arc welding or traditional spot welding machines. Despite the fact that this equipment can meet production specifications, many welding defects such as undercut, inadequate penetration, pores, and cracks are still present during the welding process.When this phenomenon appears, the joint's firmness is significantly reduced, and it becomes a direct cause of crevice corrosion. Furthermore, there are some criteria for the welding technology standard of the laser welding machine operators, and the welding cost is relatively high.

When the fiber laser cutting machine is cutting carbon steel materials, due to the high hardness of carbon steel, in order to avoid problems, it is necessary to check and maintain the fiber equipment frequently. And if there is a problem during processing, it is necessary to investigate from all aspects of the fiber laser cutting machine. Under normal cutting conditions, the effect of cutting carbon steel should be burr-free and the traction line should be consistent. So what problems should the fiber laser cutting machine pay attention to when cutting carbon steel plates? Big Picture Laser will answer for you.
