The welding speed of laser welding machine and the ability to control welding quality during operation make laser welding a widely used method in many industrial fields (such as aerospace industry, medical industry, electronics industry, tool manufacturing)
As a laser welding machine supplier from China, so many customers asked this questions to us. Here I will introduce the advantage of laser welding machine:
Laser welding is an efficient and precise welding method that uses a high energy density laser beam as a heat source. The metal absorbs the energy of the laser and melts quickly in a very short time, greatly reducing the risk of material deformation. Based on our test result, w laser welding machine to welding 2mm stainless steel, welding speed is 10m per min.
The laser welding machine can do no-touching welding. This advantage ensures that we can weld many tiny parts that are difficult to touch or see. And the welding effect is very fine and clean.
Here glad to share a sample pictures from our customers:
The laser welding machine is mainly used for welding metal materials. It can not only weld metal sheets, but also metal pipes and metal materials of different shapes.
This is the sample we welded for our customers. It is mainly used for water tanks. The welding effect is not only beautiful, but also has good air tightness and no water leakage. And the weld has better corrosion resistance.
The non-contact auto laser welding machine controlled by the computer has almost no wear and tear, and only needs to clean or replace the lens regularly.
Handheld laser welding machines require direct contact between the laser head and the material, so there is a loss of welding nozzles. At the same time he also needs to clean or replace the lenses regularly
Here is the auto laser welding machine and handheld laser welding machine picture:
The initial installation cost of laser welding machine will be higher than other welding methods
Laser welding is not suitable for welding metals with high reflectivity. Like copper
There are several types of lasers that are popular in the market you need to know now.

If you use the most suitable laser power, you will get the best welding results and save energy.
2. Make sure your focal length is correct. The correct focal length can ensure you get the biggest power.
Anyhow, with the decrease in laser source prices, the purchase cost of laser welding machines is decreasing year by year. Laser welding will become a trend to replace TIG and MIG on thin plate welding. Anyone who takes the lead in updating welding equipment to the laser industry, they will become the industry leader.
We have classified the following points into two main categories based on process and machine parameters. Why is it necessary to consider these factors?? Because these factors determine the overall specification of a laser cleaner machine. A suitable laser cleaner machine will provide the best product solution and expected performance.
According to control theory, a process parameter is a process component’s measured value. Usually, the operator monitors or controls these process parameters based on different circumstances. The following parameters help you choose the best laser-cleaning machine.
Laser machines can have two typical laser frequencies: continuous and pulsed. Continuous laser machines produce a constant flow of energy. It means that an uninterrupted laser frequency provides high-quality and effective laser beams. Continuous laser is famous for laser cutting and welding. This type of laser machine requires high energy consumption.
On the other hand, pulsed laser machines produce interrupted laser frequency at regular intervals. This laser power is famous for cleaning, marking, or etching. Therefore, it is essential to check the laser power type of the machine you are choosing.
Safety has always been the primary consideration for every laser cleaning machine. Typically, a laser machine requires a class-1 safety enclosure. It makes the work safe and reliable. Every laser machine manufacturer must meet the requirements of safety regulations worldwide. However, if you see the laser machine is already equipped with a class-1 laser safety enclosure, you won’t need any PPEs. In the case of a handheld laser cleaning machine, you should ensure the safety enclosure class. If it is class 4, then you may need additional PPE.
Some people may need clarification on cleaning and scanning speeds. A scanning speed refers to the Galvo scanners’ working speed, producing a certain laser spot width. In this case, the laser cleaning speed is perpendicular to this laser spot. For example, In Hanten CNC, different laser types offer a cleaning speed between 0.5m2/h and 15m2/h.
Cleaning times are another essential factor that you should consider. Cleaning times refer to the number of operations required for the desired cleaning properties. At different laser cleaning speeds, the surface roughness also changes. You may need consecutive laser cleaning operations to get the desired state.
During laser cleaning, the process will produce lots of contaminants. In this case, laser cleaning standards require a vaporization process to convert the pollutants into dust or fumes. It is necessary to extract these contaminants from the working space. However, ensuring this feature protects workers and keeps the functional area clean and tidy.
First, check the fume extraction nozzle position. After that, check the safety measures of PLC automated communications. Lastly, check the filter and extraction units based on the type of dust or fumes produced.
The overlap ratio is another fundamental part of laser cleaning. It is seen that overlap ratio and energy density change cleaning speed, pulse frequency, and power. Therefore, these two parameters change the total value of the surface roughness of the projected metal part.
Why is it necessary to consider this when choosing a suitable laser cleaning machine? Because it will tell you the productivity of the whole machine. You can check these properties from the lab test documents provided with the laser cleaning machine.
