Talk about the recent hot handheld laser welding machine

The development of metal welding technology is closely related to the development of modern industry and science and technology, and is constantly improving along with the application of metals. According to the characteristics of the process, it can be divided into three categories: fusion welding, pressure welding and brazing. Among them, fusion welding can be divided into argon arc welding, submerged arc welding, CO2 gas shielded welding (secondary welding), laser welding, etc.; pressure welding is divided into resistance welding, cold pressure welding, forging welding, etc.; brazing is divided into flame brazing Welding, induction brazing, etc.

1¡¢Features of laser welding

Laser welding uses the excellent directivity and high power density characteristics of the laser beam to work. The laser beam is focused on a small area through the optical system, and the welded area forms a heat source area with highly concentrated energy in a very short time. Thereby, the area to be welded is melted and solidified rapidly to form a weld spot or seam.

Compared with other welding methods, laser welding has the following characteristics:

1) Concentrated energy, fast welding speed, high efficiency, high processing precision, and large weld depth-to-width ratio;

2) Less heat input, small heat-affected zone, small residual stress and deformation of the workpiece;

3) The welding energy can be precisely controlled, the welding effect is stable, the welding seam is beautiful and smooth, and the consistency is good;

4) Laser welding is green and safe. Traditional arc welding will produce a lot of dust, welding slag and arc radiation.

2¡¢The rise of handheld laser welding

The hand-held laser welding machine is favored by users for its high welding quality, fast speed, easy operation, energy saving and environmental protection, etc. It has gained a place in the market and ushered in explosive growth. Handheld laser welding can be widely used in industries such as stainless steel furniture, cabinets, kitchens and bathrooms, distribution boxes, shelves, stair elevators, door and window guardrails, etc.

For production workshops engaged in small-scale processing or non-large-scale welding, compared with automated laser welding workstations, handheld laser welding is the best choice. It does not require special equipment and welding workbenches, and occupies a small space. The shape is flexible, and the laser hand-held welding machine can fully meet the needs of this kind of production.

3¡¢Advantages of handheld laser welding

Hand-held laser welding has obvious advantages in terms of welding speed, welding quality, follow-up processing (smooth and smooth without manual grinding) and other metal materials such as thin stainless steel plates, iron plates, and aluminum plates. , carbon neutrality, so there is a strong potential to replace traditional processes.

Based on the integrated design concept, the laser, water cooling system, welding torch, wire feeder and control part are integrated together, which occupies a smaller area and requires less space. Equipped with moving pulleys, the station can be adjusted at any time according to site requirements, which is convenient and flexible . It has the advantages of simple operation, beautiful weld seam, fast welding speed, and no consumables. It can perfectly replace traditional argon arc welding and electric welding.

The rapid growth of handheld laser welding manufacturers is due to the fact that in addition to identifying market opportunities and operating quickly, Japanese and foreign products (IPG) have not entered the stage in the early stage of the industry, and the relatively low threshold for R&D and technological innovation is also the main factor. At the same time, traditional arc welding manufacturers, existing high-end laser application manufacturers and channel manufacturers have also entered the field of handheld laser welding one after another.
