Laser is a new energy source that enables welding, cutting and other processing methods, and is one of the very advanced manufacturing processes. Laser welding machines use the laser as the source of energy, combining a variety of functions in one, and have a wide range of uses.
Principle of laser welding machine
Laser welding machine uses the huge energy of laser pulse to heat the material to be processed in a small area, and eventually melt it to form a specific molten pool, which can realize spot welding, butt welding, stack welding, sealing welding, etc. It opens up a whole new field of application of laser welding with its unique advantages, and provides precision welding for thin-walled materials and micro-small parts.
Laser welding machine use
1. Welding
The main purpose of the laser welding machine is undoubtedly welding, not only can weld stainless steel plate, aluminum plate, galvanized plate and other thin-walled metal materials, but also can be used for sheet metal welding, such as kitchen utensils, suitable for its plane, straight line, arc and any shape of the weld, is widely used in precision machinery, jewelry, electronic components, batteries, clocks and watches, communications, handicrafts, and other industries in a variety of complex environments can be a good completion of welding, high productivity than the traditional welding machine. Welding, high productivity, than the traditional argon arc welding, welding and other processes have more obvious advantages.
Using laser welding machine, the weld width is small, depth is large, thermal shock area is small, deformation is small, weld seam is smooth and beautiful, high quality welding, no porosity, can be accurately controlled, welding quality is stable, no need to deal with after welding or simple treatment can be.
2. Cleaning
By replacing the laser nozzle and cleaning lens, it can realize the function of cleaning the material surface, effectively removing rust spots, oxidized layer, oil, etc. on the material surface without destroying the surface characteristics. With the characteristics of non-contact, no need for cleaning fluid, can replace the professional cleaning equipment.
3. Cutting
Welding and cutting are often inseparable, the laser welding machine combines the functions of the two together, and can be used to cut metal materials, such as copper, aluminum, stainless steel, carbon steel, galvanized plate, etc., to meet the conventional thin plate type of cutting needs.
Simple cutting can be carried out, welding and cutting can be freely switched, just change the welding copper nozzle to cutting copper nozzle, very convenient.
4. Welding bead cleaning
It can effectively remove oxides, welding slag, oil, dust and other impurities generated during the welding process, making the surface of the weld bead clean. This not only helps to improve the quality of the weld, but also enhances the strength and appearance of the weld. Laser cleaning is highly accurate and controllable, and thoroughly cleans the weld surface without damaging the base metal.
