How Much does A Handheld Laser Welder Cost

At present, the average cost of the handheld laser welding machine on the market is about 7,000 US dollars. The power of the laser welding machine on the market is 1500w laser welding machine, 2000w laser welder, and an affordable 1000W portable laser welding machine starts at 5,500 US dollars, which is More suitable for beginners and home enthusiasts.

What can handheld laser welder welded

1000W laser welding machine 2mm thick stainless steel plate requires complete welding, the finer the welding, the better. It is recommended to use 1000W fiber laser for welding, the speed can be greater than 1 m/min, also can use 500W but the speed is slower.Handheld welding machine welding different thickness.

  • The 1500 watt laser welding machine can weld stainless steel within 5 mm.
  • The 2000 watt laser welding machine can weld stainless steel within 8 mm.
  • The 2500 watt laser welding machine can weld stainless steel within 10mm.
  • The 3000 watt laser welding machine can weld stainless steel within 12mm.

How does a laser welder work

The handheld laser welding machine uses high-energy laser beams/pulses to locally heat the required welding area of the material, so that the energy diffuses into the material through heat conduction, and the material is melted to form a specific molten pool, so as to achieve the purpose of welding.

Because the laser is not a simple mechanical device, but is emitted by the laser after being refracted by the lens. In this process, a control system is required to control parameters such as power, direction, and angle. Therefore, a hand-held laser welding control system is required to complete the overall planning. This series of operations, in simple terms, the laser control system is the brain of the laser equipment.

Advantages of handheld laser welding machine

Laser welding is a new welding method. Laser welding is mainly aimed at the welding of medium and thin plate materials and precision parts. It can realize spot welding, butt welding, lap welding, sealing welding, etc., with its characteristics.

(1) High depth-to-width ratio, small weld width, small heat-affected zone, small deformation, and fast welding speed;

(2) The welding seam is smooth and beautiful, and no treatment or simple treatment is required after welding;

(3) The quality of the weld is high, without porosity, which can reduce and optimize the impurities of the base metal, and the structure can be refined after welding, and the strength and toughness of the weld are at least equal to or even exceed that of the base metal;

(4) It can be precisely controlled, the focusing spot is small, it can be positioned with high precision, and it is easy to realize automation;

(5) Welding between some dissimilar materials can be realized.

Components of a handheld laser welding machine

The handheld laser welding machine is mainly composed of a laser, a control system, a welding head, a cooling system, a wire feeding system, etc.

Laser

The laser source is the laser generator, which is the heat source supply for the laser welding system. Since the first ruby laser came out in 1960, there have been many kinds of laser generators on the market, and the beam quality has been continuously improved, laying the foundation for the development of laser processing technology.

Handheld laser welding system

That is, the hand-held welding board card controls all aspects of the work of the hand-held welding equipment. At present, it is mainly a touch screen system, which is easy to use in terms of operation.

Welding head

The welding head refers to the laser processing tool. Different laser processing technologies correspond to different laser processing tools. Hand-held welding equipment depends on the power, and manual cutting operations can also be completed in some cases.

Cooling system

Due to the unavoidable emission of a large amount of heat when the laser occurs, in order to ensure the normal operation of the laser source, a cooling system is required to ensure a constant temperature of the laser source. Currently, there are two types of hand-held welding cooling systems on the market: air-cooled and water-cooled.

How to use laser welding machine

1.Before operation, that is, before running the handheld laser welding machine, we need to do a series of inspections, and then turn on the machine after the inspection is completed, so as to ensure that the welding machine can run more smoothly during operation.

First of all, we have to carefully check whether the reflective lens of the handheld laser welding machine is clean. If there is some dust on it, it must be cleaned in time, otherwise the contaminated lens may explode during the work process.

After checking the lens, we have to do other corresponding adjustment work, and the other adjustment work is relatively simple, and it is also to check whether there are loose parts in other places.

2.After the inspection, we can avoid some problems that will occur during the working process of the handheld laser welding machine, but in the actual welding process, other failures will also occur.

Then we have to control the occurrence of these problems. If it is found that the processing effect and processing efficiency are not as good as before during the processing, the first thing we have to consider is whether the materials of our laser welding machine have changed, because different The consideration of material processing is also different. If this is the reason, we can adjust the parameters of each item, and then do some tests to see the situation.

3.Then there are still matters needing attention, that is, we must ensure that the working environment of the handheld laser welding machine is relatively good, and the lighting and cleanliness must meet relatively good requirements, although everyone may think that the working environment of the laser welding machine does not need to be particularly good , but only with a better environment, the laser welding machine can work faster.

In order to give full play to the advantages of jewelry laser welding machines, we also need to reduce some bad situations in the production process to reduce production costs.

Common problems of handheld laser welding machine:

1: The protective lens of the welding torch head is consumed too much

The nozzle of the welding gun is downward in normal welding. If the vertical welding is welded from top to bottom, it may cause sparks to fall into the inside of the gun head and cause damage. Generally, the flat welding is to weld the gun head to the material at an oblique angle of 45° from front to back. It is recommended to replace the protective lens for the surrounding environment, and the outside of the gun head should be kept with masking paper as much as possible. Avoid long-term use of dust into the interior.

2: The focusing mirror, reflector, and QBH lens are damaged

This is the main 3 lenses in the gun except for the fragile protective lens. If one of the three lenses is broken, the welding torch must be removed and mailed back to the manufacturer to replace the lens in a dust-free environment. The lens is damaged, the power is insufficient, and the laser If there is no focusing, distraction, and red welding nozzle, you must stop welding and check whether the protective lens and other lenses are damaged.

3: The wire feeder is stuck

In the case of jamming, check whether the nozzle of the gun is unobstructed, whether the wire feeding tube is unobstructed, and whether the rotation of the wire reel is normal. The basic inspection is these places, especially for welding aluminum materials. Everyone must pay attention to the hardness of aluminum materials. It is too low, so it is easy to cause blockage and poor wire feeding.
