Laser technology is relatively advanced in various industries. The emergence of hand-held laser welding machines has subverted the traditional welding technology and made a qualitative leap in the laser welding industry. Handheld laser welding machines can weld workpieces of different materials together. Let’s get rid of some of the annoyances and limitations of traditional machining.

Traditional welding is a method in which the workpiece interface is heated to a molten state during the welding process, and the welding is completed without pressure. During fusion welding, the heat source rapidly heats and melts the interface between the two workpieces to be welded, forming a molten pool. The molten pool gradually moves forward with the heat source, and after cooling, a continuous weld is formed, connecting the two workpieces into one. This welding method was an early welding method that really made a big contribution at the time. Today, the laser industry is constantly evolving and new skills are constantly being introduced. Handheld laser welding machines have gradually replaced traditional welding machines, and the welding speed can reach 5-10 times that of traditional welding.

Handheld laser welding machine, one machine can complete a variety of welding methods, common hand-held operation methods can complete the welding of any part of the workpiece, any angle; suitable for tailor welding, stitch welding, internal and external fillet welding, arc welding, special-shaped welding, etc. . The welding process does not consume any material, just replace the copper nozzle. The satisfaction is that the operation of the hand-held welding equipment is very simple, and the requirements for the welder are basically zero, which is called “fool-style” operation in the industry.

Which brand of handheld laser welding machine is good

Handheld laser welding machines have a good reputation in the welding market. Handheld laser welding machines are gradually used by the majority of occupations due to their simple and convenient operation, good welding efficiency, and welding field strength.

Handheld laser welding machine is a new type of welding equipment, which introduces new technology and new technology to form automatic welding. It is a simple and easy-to-operate portable device. It is also a new type of fine welding equipment, suitable for various environments including on-site welding. The hand-held laser welding machine replaces the traditional fixed welding torch optical path, which is more flexible and convenient. To achieve on-site welding, the traditional laser welding machine can only perform fixed welding, which has limitations in the welding of some large workpieces, and the selectivity is small.

The labor cost of handheld laser welding is low; the labor cost of argon arc welding skills is about 7K per month, which is not a small amount in one year. Handheld fiber laser welding machine, used by ordinary workers or novices, 4K-5K per month, can save 3.8W a year. The hand-held fiber laser welding machine is highly replaceable, has low requirements for technicians, and saves labor costs.

The hand-held laser welding machine does not require consumables for welding. It can be automatically operated by filling wire and replacing the maintenance mirror, reducing subsequent processing, saving materials and time. A variety of welding methods: free switching between vertical fillet welding, splicing welding, vertical welding, etc., suitable for a variety of raw materials, widely used in mobile phone accessories, kitchenware industry, bathroom industry, aviation industry, door and window industry, etc.

Handheld laser welding machine features:

Lightweight and flexible, easy to operate, can meet multi-angle multi-position welding;

Equipped with 5m/10m imported optical fiber, flexible and convenient outdoor welding;

Verification of the welding head position by infrared positioning to verify the position during the welding process. The welding position is more accurate, the welding seam is flat and beautiful, easy to polish and polish, and no processing or a simple process is required after welding;

360 degree micro welding without dead angle. After the laser beam is focused, the spot is small, the power density is high, and the positioning accuracy is high. It can be used for assembly welding of small and micro workpieces to realize automatic mass production;

The laser welding depth is large, the welding seam is firm, the width is small, the heat affected zone is small, the deformation is small, and the welding speed is fast. It can realize complex welding between some dissimilar materials;

High quality welds, no pores, can reduce and optimize base metal impurities, post-weld microstructure refinement, weld strength and toughness at least equal to or even higher than base metals;

The output is stable and the welding consistency is guaranteed. Most CW laser welders are a high power laser with power over 500 watts. Generally, this kind of laser is applied to the sheet of more than 1mm. There are also some low-power CW lasers with power ranging from tens of watts to hundreds of watts, which are widely used in the plastic welding and laser brazing industries.
