Features and applications of hand-held fiber laser welding machine

The hand-held fiber laser welding machine is a new generation of laser welding equipment. It belongs to non-contact welding. And the operation process does not require pressure. Only irradiate a high-energy intensity laser beam on the surface of the material. Then melted inside material through the interaction of the laser and the material. At last cool and crystallize to form a weld.

The hand-held fiber laser welding machine fills the gap of hand-held welding, subverts the working mode of the traditional laser welding machine, and replaces the previous fixed optical path with a hand-held type. It is flexible and convenient, and the welding distance is long. It also makes the operation of laser welding in outdoor changes become possible.

Hand-held welding work for laser welding of long-distance and large workpieces. It overcomes the limitation of the worktable’s stroke space. The heat-affected area during welding is small, and it will not cause work deformation, blackening, and traces on the back. The welding depth is large. It is firm and fully melted. It can not only realize thermal conduction welding, but also continuous deep penetration welding, spot welding, butt welding, stitch welding etc.

This process overturns the working mode of the traditional laser welding machine. As a result, the advantages are simple operation, beautiful welding seam, fast welding speed, and no consumables.

Besides it is perfect for welding thin stainless steel plates, iron and galvanized plates and other metal materials. Also it replaces traditional argon arc welding.

Advantages of hand-held laser welding machine

1. Wide welding range

There are 5m-10m original optical fiber. It overcomes the limitation of workbench space, and weld outdoors and long-distance welding;

2. Convenient and flexible to use

Hand-held laser welding is with movable pulleys, which is comfortable to hold and can adjust the working position at any time. It is free and flexible, and suitable for various working environment scenarios.

3. A variety of welding methods

Weld at any angle, such as overlap welding, butt welding, vertical welding, flat, internal and external fillet welding etc., and can weld various complex welded workpieces and large workpieces with irregular shapes. In addition, it can also complete the cutting, switch the welding and cutting freely, just change the welding copper nozzle to the cutting copper nozzle.

4. Good welding effect

Hand-held laser welding is thermal fusion welding. Compared with traditional welding, laser welding has a higher energy density and can achieve better welding results. The welding area has little thermal influence, which is not easy to deform and has traces on the back. The welding depth is large, the melting is sufficient, and it is firm and reliable, and the welding seam strength reaches or exceeds the base metal itself.

5. Welding seam does not need to polish

After traditional welding,  needs to polish the welding point to ensure that it is smooth. The hand-held laser welding precisely has more advantages: continuous welding, smooth and beautiful, and fewer follow-up polishing procedures.

6. Welding without consumables

In most people’s impression, the welding operation is “left hand goggles, right hand clamp welding wire”. But with the handheld laser welding machine, can complete the welding easily, which reduces the material cost in production and processing.

7.Safety

With multiple safety alarms, the welding tip is only effective when it touches the metal, and the light is automatically locked after the workpiece is removed, and the touch switch has body temperature sensing. The safety is high to ensure the safety of the operator during work.

8. Save labor cost

Compared with arc welding, the processing cost can be reduced by about 30%. The operation is simple, easy to learn, and quick to get started. The technical threshold of operators is not high. Ordinary workers can take up their posts after a short training, which can easily achieve high-quality welding results.

Comparison of hand-held laser welding machine and argon arc welding

1. Energy consumption comparison:

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 hand-held welding can complete dissimilar steel and dissimilar metal welding. The speed is fast, the deformation is small, and the heat-affected zone is small. The weld seam is beautiful, smooth, no/less porosity, and no pollution. The handheld laser welding machine can be used for small open parts and precision welding.

3. Follow-up process comparison:

low heat input during laser hand-held welding, small deformation of the workpiece, beautiful welding surface can be obtained, no or only simple treatment. The handheld laser welding machine can greatly reduce the labor cost of the huge polishing and leveling process.

Application field of hand-held laser welding machine

Mainly applicate in large and medium-sized sheet metal, cabinets, chassis, aluminum alloy door and window frames and other large workpieces, such as inner and outer right angle and flat weld welding. The heat-affected area during welding is small, the deformation is small, and the welding depth is large.

Widely used in advertising industry, mold industry, stainless steel products industry, as well as stainless steel engineering industry, door and window industry, and handicraft industry, auto parts industry, etc.
