The hand-held fiber laser welding machine is a new generation of laser welding equipment. It belongs to non-contact welding. It does not require pressure during the operation. , which melts the material inside, and then cools and crystallizes to form a weld.

Handheld welding is an advantageous operating device for thin-walled metal welding. It is also a precision welding device, but can be used freely and flexibly in various environmental applications. It can be easily applied in various types of environments with higher professional standards and reliability. The professional production target of hand-held welding machine has the advantages of high standard and specialization.

At the same time, it is also a practical and user-friendly design in the process of ensuring accurate welding targets. At the same time, it improves welding defects in traditional welding processes, such as undercut, incomplete penetration, dense pores and cracks. The hand-held fiber laser welding machine seams are smooth and beautiful, which reduces the subsequent grinding process and saves time and time. With high cost, few consumables and long service life, it is well received by the market.

1. Advantages of handheld laser welding

a. Wide welding range: The handheld welding head is equipped with 5m-10m original optical fiber, which overcomes the limitation of the workbench space and can be used for outdoor welding and long-distance welding;

b. Convenient and flexible to use: Hand-held laser welding is equipped with moving pulleys, which is comfortable to hold, and can be adjusted at any time without a fixed-point station, which is free and flexible, and is suitable for various working environment scenarios.

c. Various welding methods: welding at any angle, stitch welding, butt welding, vertical welding, flat fillet welding, inner fillet welding, outer fillet welding, etc., can be used for various complex weld workpieces and irregular shapes of larger workpieces. Welding and welding at any angle. In addition, the cutting can be completed, and the welding and cutting can be switched freely. It is very convenient to change the welding copper nozzle to the cutting copper nozzle.

d. Good welding effect: hand-held laser welding is hot-melt welding. Compared with traditional welding, laser welding has higher energy density and can achieve better welding effect. Trace problems, large welding depth, sufficient melting, firm and reliable, and weld strength reaching or even exceeding the base metal itself, which cannot be guaranteed by ordinary welding machines.

e. Simple operation, can easily achieve high-quality welding effect

f. Suitable for small-scale production: Compared with fully automatic equipment deployment, the hand-held laser welding machine has a lower production compliance rate. But for production workshops engaged in small-scale processing or non-large-scale welding, manual laser welding is a better choice, no need to set up equipment to deploy welding stations, small footprint, flexible product shapes for the diversification of welding products, and laser hand-held welding The machine can fully meet the needs of this kind of production.

g. Low maintenance cost: There is no need to add welding wire during hand-held laser welding, and there is basically no cost of consumables. The life of the pump source is more than 100,000 hours, and the daily maintenance is basically free, saving labor and worry.

2. Comparison of handheld laser welding machine and argon arc welding

a. Energy consumption

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

b. Welding effect

Laser hand welding can complete dissimilar steel and dissimilar metal welding. Fast speed, small deformation and small heat affected zone. The welding seam is beautiful, flat, no/less porosity, no pollution. Handheld laser welding machines for tiny open parts and precision welding.

c. Subsequent procedures

During laser hand-held welding, the heat input is low, the deformation of the workpiece is small, and a beautiful welding surface can be obtained, without or only a simple treatment (depending on the welding surface effect requirements). The hand-held laser welding machine can greatly reduce the labor cost of the huge polishing and leveling process.

3. Application fields of hand-held laser welding machine

Hand-held laser welder can be widely used in complex and irregular welding processes in cabinet kitchen and bathroom, stair elevator, shelf, oven, stainless steel door and window guardrail, distribution box, stainless steel home and other industries. It is also widely used in kitchens, household appliances, advertising, molds, stainless steel doors and windows, handicrafts, household items, furniture, auto parts and many other industries.
