Laser welding principle:

The laser welding machine uses a high-intensity laser beam to radiate to the metal surface, locally heats the material in a small area, and melts the material to form a specific molten pool to achieve the purpose of welding.

Laser welding features:

Lasers are considered an ideal heat source for welding and are recognized as high technology. Laser welding has the advantages of concentrated heating, less heat input, small deformation, and fast welding speed; large weld depth ratio, flat weld, beautiful appearance, no need or simple treatment after welding, high weld quality, no pores; can be precisely controlled , The focusing spot is small, the positioning accuracy is high, and it is easy to realize automation; it is not only suitable for conventional materials, but also especially suitable for insoluble metals and heat-resistant alloys. Titanium alloys have dissimilar metals with large differences in thermophysical properties, workpieces with large differences in volume and thickness, and components near the weld that are flammable, cracked and explosive when heated. Compared with vacuum electron beam welding, laser welding has the advantages of not generating X-rays, no vacuum chamber, and unlimited workpiece volume. Laser welding can be used as a final process, and the weld is beautiful and beautiful, and in many cases the weld can be as strong as the base metal. Laser welding can not only spot welding, but also continuous seam welding, stitch welding, sealing welding, etc., with high aspect ratio, small weld width, small heat affected zone and small deformation.

Scope of application:

Welding of precision parts such as microelectronic components and integrated circuit leads, welding of high-power diodes, mobile phone batteries, electronic components, etc., precision welding of jewelry, welding of precision parts, laser welding repair of molds, and glasses welding.


Laser welding machine is also known as laser welding machine, laser welding machine, the specific classification is as follows:

Handheld Laser Welding Machine:

This is probably the most common type of welding equipment on the market. Often used for welding various metal sheets.

Laser spot welding machine:

It can be used for gold and silver jewelry, hole filling of electronic components, spot welding trachoma, welding inlay, etc.

Automatic Laser Welding Machine:

It is suitable for automatic welding of straight lines and circles of metal workpieces, and is often used in mobile phone batteries, jewelry, electronic components, sensors, watches, precision machinery, communications, handicrafts and other industries.

Laser Die Welder:

It is mainly used for mold repair in mold manufacturing and molding industries such as mobile phones, digital products, automobiles and motorcycles, and is also mostly used for manual welding.

Fiber Transmission Laser Welding Machine:

For the parts that are difficult to access to welding, flexible transmission non-contact welding is implemented, which has greater flexibility. The laser beam can realize the splitting of time and energy, and can perform multi-beam simultaneous processing, which provides conditions for precision welding.

Fiber galvanometer laser welding machine:

The perfect combination of galvanometer motion system and laser welding machine system. Effectively save the idle positioning time during single-point welding, and increase the efficiency by 3 to 5 times compared with the traditional electric worktable
