What are the working purposes of laser welding machines?
Laser is regarded as one of the emerging energy sources, endowing the manufacturing industry with advanced processes that can achieve various processing methods such as welding and cutting. Laser welding machine, as a tool that integrates multiple functions, uses laser as an energy source and has a wide range of applications.
Working principle of laser welding machine
Using high-energy laser beams to heat the welding material to the temperature of melting or fusion, thereby achieving welding connections. The laser beam is focused by an optical system, producing high-density energy at the focal point, which rapidly heats up the welding material, reaches the melting point, and forms a welding pool. By controlling the focusing position and power of the laser beam, the melting and fusion depth of the welding process can be controlled, thereby achieving accurate welding results. Laser welding machines can be widely used for welding various materials, with the characteristics of high precision, high efficiency, and non-contact, so they are widely used in industrial production.
Laser welding machines use laser pulses to release enormous energy, locally heating the materials to be processed and melting them to form specific molten pools. Through this method, laser welding machines can achieve various welding methods such as spot welding, butt welding, overlap welding, and seal welding. Laser welding machines, with their unique advantages, have opened up new application areas in the field of laser welding, providing precise welding technology for thin-walled materials and micro parts.
Application fields of laser welding machines
1. Welding
The main purpose of a laser welding machine is to perform welding. It can not only weld thin-walled metal materials such as stainless steel plates, aluminum plates, galvanized plates, but also weld sheet metal parts, such as kitchen utensils. It is suitable for welding flat, straight, curved, and any shape, with a wide range of applications, including precision machinery, jewelry, electronic components, batteries, clocks, communication, handicrafts and other industries. Not only can welding be completed in various complex environments, but it also has high production efficiency. Compared to traditional processes such as argon arc welding and electric welding, it has more obvious advantages.
By using a laser welding machine, flexible control of welding seam width and depth can be achieved, with small thermal shock surface, small deformation, smooth and beautiful weld surface, high welding quality, no pores, and precise control. The welding quality is stable, and it can be used after completion without the need for tedious processing.
2. Repair
Laser welding machines can not only be used for welding, but also for repairing wear, defects, scratches on molds, as well as defects such as sand holes, cracks, and deformations in metal workpieces. When the mold is worn out due to prolonged use, discarding it directly can cause huge losses. Repairing problematic molds through laser welding machines can save production time and costs, especially when repairing fine surfaces, avoiding subsequent thermal strain and post weld treatment processes. In this way, after the repair is completed, the mold can be reused, achieving full utilization again.
3. Cutting
Laser cutting is an innovative cutting process that uses laser welding machines to achieve high-precision cutting of metal materials such as stainless steel, copper, aluminum, zirconium, and other alloys. In addition, this technology can also be used to process non-metallic materials such as plastics, rubber, wood, etc. Therefore, laser cutting is an important application of laser welding machines in the field of material processing.
Laser welding machine is used for cleaning and rust removal.
4. Cleaning
With the continuous reform and update of laser welding machines, their functions are increasing day by day. Not only can it be welded and cut, but it can also be cleaned and rust removed. The laser welding machine utilizes the light beam emitted by the laser to remove the contamination layer on the surface of the processed workpiece. The use of laser welding machines for cleaning has the characteristic of non-contact and does not require the use of cleaning liquids, which can replace professional cleaning equipment.
