The working principle of laser welding machine:
Laser welding machine is usually also called laser welding machine, energy negative feedback laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment, etc.
Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses into the material through thermal conduction, and the material melts to form a specific molten pool. It is a new type of welding method, mainly used for welding thin-walled materials and precision parts. It can achieve high aspect ratio, small weld width, small heat affected zone spot welding, butt welding, seam welding, sealing welding, etc. Small deformation, fast welding speed, smooth and beautiful welding seam, no need to handle or simple processing after welding, high welding seam quality, no porosity, precise control, small focus, high positioning accuracy, and easy to realize automation.
Which industries are suitable for the use of laser welding machines
Products with welding requirements
Products that require welding seams are welded with laser welding equipment, which not only has small weld seams, but also does not require solder.
Highly automated products
In this case, the laser welding equipment can be manually programmed for welding, and the path is automatic.
Products at room temperature or under special conditions
It can stop welding at room temperature or under special conditions, and the laser welding equipment is easy to install. For example, when laser light passes through an electromagnetic field, the beam will not be deflected. The laser can be welded in vacuum, air and certain gas environments, and can pass through glass or materials that are transparent to the beam to stop welding.
Some inaccessible parts require laser welding equipment
It can weld hard-to-reach parts and realize non-contact remote welding with high sensitivity.
Especially in recent years, under the condition that YAG laser and fiber laser technology are very mature, laser welding technology has achieved more general promotion and application.
