laser welding machine is a process used to join together metals or thermoplastics using a laser beam to form a weld. Being such a concentrated heat source, in thin materials laser welding can be carried out at high welding speeds of metres per minute, and in thicker materials can produce narrow, deep welds between square-edged parts.

The beam modes of different fiber laser welding machines have the following effects on laser weld penetration:

1. Under the condition of a certain laser power, as the welding speed decreases, whether single-mode or multi-mode lasers are used, the weld penetration will gradually increase.


2. Under the condition of certain laser power, as the defocusing amount decreases, whether single-mode or multi-mode lasers are used, the weld penetration will gradually increase.


3. When the power, defocus and speed remain unchanged, the welding penetration of single-mode lasers is larger than that of multi-mode lasers.

What is the maintenance method for the laser welding machine?

1. In a high temperature or humid environment, the torch laser should be observed at all times to observe whether there is a “condensation” phenomenon caused by low water temperature on the pipeline or the laser concentrating cavity of the cooling water circulation. The appearance of "condensation" will cause damage to the end face of the crystal, resulting in a drop in output power or even no light. Care must be taken during use. If “condensation” occurs, stop using the  laser welding machine. After the moisture on the surface of the concentrating cavity is naturally dried, check the condition of the  optical surface to determine whether to clean the rod and check that everything is normal. Before turning on the power, pay attention to properly setting the lower limit setting temperature of the high temperature controller. In normal operation, attention should also be paid to observing frost on the titanium tube of the refrigeration system. If frost formation occurs, it may be caused by insufficient freon in the refrigeration system. Immediately ask the relevant professionals to supplement and check for leaks;


2. laser welding equipment operators can often use black paper to check the laser output spot, once the spot is uneven or the energy is reduced, the resonator cavity should be adjusted in time to ensure the beam quality of the laser output.


3. The purity of the cooling water is the key to ensure the laser output efficiency of the welding torch and the life of the laser concentrating cavity component. The conductivity of the circulating water should be checked once a week to ensure that its conductivity is 30.5 MWcm, and the internal circulation must be replaced once a month. The deionized water, the conductivity of the newly injected pure water must be 32MWcm. Always observe the color change of the ion exchange column in the cooling system. Once the color of the resin in the exchange column is found to be dark brown or even black, replace the resin immediately.


4. In order to ensure that the torch laser has been in normal working condition, after two weeks of continuous operation or stop using for a period of time, first check the components in the optical path such as YAG rod, dielectric diaphragm and lens protection glass before starting the machine, and determine each The optical components are free from abnormal phenomena such as dust pollution and mildew. If any of the above phenomena are present, they should be treated in time to ensure that the optical components are not damaged by strong laser irradiation.


Advantages of handheld laser welding:

The heat input can be reduced to the minimum required amount, the metal lographic change range of heat affected zone is small, and the deformation caused by heat conduction is also the lowest.

The welding process parameters of 32mm thick single pass welding have passed the verification, which can reduce the time required for thick plate welding and even save the use of filler metal.

There is no need to use electrodes, and there is no concern about electrode pollution or damage. And because it does not belong to the contact welding process, the wear and deformation of machines and tools can be minimized.

The laser beam is easy to focus, align and be guided by optical instruments. It can be placed at an appropriate distance from the workpiece and can be re-guided between machines or obstacles around the workpiece. Other welding rules cannot be used because of the above space restrictions.

The workpiece can be placed in a closed space (under the control of vacuumizing or internal gas environment).

The laser beam can be focused in a small area, and small and closely spaced parts can be welded.

There is a wide range of weldable materials, and various dissimilar materials can be joined with each other.

It is easy to carry out high-speed welding with automation, and can also be controlled by digital or computer.

When welding thin materials or small-diameter wires, there will be no trouble of reflow like arc welding.

10, is not affected by the magnetic field (arc welding and electron beam welding is easy), can accurately align the weldment.


two metals with different physical properties (such as different resistances) can be welded

No vacuum or radiation protection is required.

if welding is done by perforation, the depth-width ratio of weld bead can reach 10:1

The device can be switched to transmit the laser beam to multiple workstations.


Laser welding machine Application

This machine is suitable for welding of gold, silver, titanium, nickel, tin, copper, aluminum and other metal and its alloy material, can achieve the same precision welding between metal and dissimilar metals, has been widely used in aerospace equipment, shipbuilding, instrumentation, mechanical and electrical products, automotive and other industries.
