Laser Welder Machine Manual

It consists of laser, welding system, handheld laser gun and cooling system. It replaces traditional welding methods, such as electric welding, TIG welding, etc., to weld large workpieces with less consumables. The laser is directly irradiated on the welding area, and the workpiece is melted by high temperature, thereby realizing the welding process. Compared with the traditional welding machine method, it is faster, the weld is flatter, the welding penetration is deeper, and the welding is stronger. It is the most advanced welding equipment at this stage. It is simple to operate and can be used by no experienced personnel to weld beautiful products. Can be applied to carbon steel, stainless steel, galvanized sheet, aluminum, copper and other metals.

Features of laser welder machine manual

1. It adopts a fully enclosed optical path design, which has the advantages of dustproof and good sealing; it can work continuously for a long time (up to 24 hours).

2. The self-developed Wobble welding head is small and lightweight, easy to operate and flexible.

3. Has a variety of security alarm functions. The trigger switch is activated only when the soldering copper tip touches the metal and the safety clip clamps the metal plate. After the welding copper nozzle takes out the workpiece, the light will be automatically locked. The safety of the machine is very high, ensuring the absolute safety of the operator when working.

4. Use infrared positioning to verify the position of the welding head and verify the position during the welding process. The welding position is more accurate, the weld is smooth and beautiful, easy to grind and polish, and no post-weld treatment is required or only simple treatment is required.

5. Equipped with multi-purpose nozzles to meet various functions such as welding, cutting, and cleaning.

Details of laser welder machine manual

1. Laser welding head

Lightweight, only 0.8KG, flexible and convenient for welding metal parts of any shape, adjustable weld width, capable of long-distance welding up to 10 meters. Equipped with a safety temperature monitoring system.

2. Operation interface

Multilingual intelligent control panel, flexible adjustment of welding parameters, multiple sets of welding parameter libraries, cumulative timing of light output, etc.

3. Automatic wire feeding system

Touch screen design, automatic wire filling, fully digital design, supports stainless steel and aluminum wires with diameters of 0.8mm, 1.0mm, 1.2mm, 1.6mm, and 2.0mm.

4. Laser source

We use custom-made fiber with a minimum core diameter of 20um, which has deeper penetration depth and a laser lifespan of up to 100,000 hours. It is maintenance-free and has Bluetooth functionality.

5. Chiller

Dual-cycle water cooling system provides better cooling for the laser source and welding head. The temperature control sensor uses imported brands.

6. Welding connection fiber

The 10-meter-long optical cable adopts an integrated design, effectively avoiding damage to the fiber and problems caused by moisture, greatly improving the service life of the laser components.

Advantages of laser welder machine manual

1. High flexibility: Since the laser beam is used to scan the surface of the workpiece for welding, it can be customized according to the customer's requirements and actual conditions, so that various processes can be performed, such as welding, cutting, cleaning, etc.

2. Wide scope of application: Since laser beam is used for welding, it can be used to weld various metal materials.

3. High welding quality: Since the workpiece is welded through precision optical components, the welding quality is very high, which can ensure the high quality and stability of the entire welding process.

4. Fast welding speed: Since high-speed welding can be achieved, fast welding can be achieved, and the welding speed can also reach a very high level, and even millisecond-level welding speeds can be achieved.

5. Low welding cost: The machine has a service life of up to 100,000 hours and is maintenance-free and installation-free. Compared with traditional arc welding and argon arc welding (TIG or MIG welding machines), the processing cost can be reduced by about 30%.

Remark: Double weld thickness can be achieved if the material is welded from both sides in two times.

Other optional features

Cleaning function

By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be realized, effectively removing rust spots, oxide layers, oil stains, etc. on the material surface without damaging the surface characteristics. It is non-contact and does not require cleaning fluid, so it can replace professional cleaning equipment.

Cutting function

Simple cutting is possible, welding and cutting can be switched freely, just change the welding copper nozzle to the cutting copper nozzle, which is very convenient.

It can cut stainless steel, carbon steel, aluminum, aluminum alloy, iron and other metal sheets with a maximum cutting thickness of about 2mm.

Weld bead cleaning function

It can effectively remove oxides, welding slag, oil, dust and other impurities produced during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances its strength and appearance. Laser cleaning is highly precise and controllable, thoroughly cleaning the weld surface without damaging the base material.

Welding method

There are various welding methods to choose from, allowing for welding at any angle, including overlay welding, butt welding, vertical welding, fillet welding, inside corner welding, outside corner welding, etc. These methods can be used for welding various workpieces, including complex welds and irregularly shaped workpieces, especially larger ones.

Comparison of handheld laser welder and tig welding

1. Comparison of energy consumption

Compared with traditional arc welding, the handheld laser welding machine saves about 80%-90% of electric energy, and the processing cost can be reduced by about 30%.

2. Welding effect comparison

Laser handheld welding can complete dissimilar steel and dissimilar metal welding. Fast speed, small deformation, small heat affected zone. Weld seam is beautiful, flat, no/few porosity, no pollution. Handheld laser welding machine can perform tiny open parts and precision welding.

3. Comparison of follow-up process

Laser handheld welding with low heat input, workpiece deformation is small, you can get a beautiful welded surface, no need or only need to be briefly processed (depending on the welding surface effect requirements). Handheld laser welding machines can greatly reduce the labor cost of the huge polishing and leveling process.

Application materials

Suitable for stainless steel, copper, aluminum, gold, chromium, silver, titanium, nickel and other metals or alloys. It can also be used for various weldings between different materials, such as copper-brass, titanium-molybdenum, titanium-gold, nickel-copper, etc.

Application industry
