How Thick Can the 1000w Handheld Laser Welding Machine be Welded?

Hand-held laser welding machines are currently widely used in the metal welding market because they are simple to operate, convenient and quick to use, and save labor. But the price of hand-held laser welding machines is a problem that people are more concerned about. If you want to learn about handheld laser welding machines, just take a look at the following article.

Many friends don’t know how thick a hand-held laser welding machine can weld plates. Of course, the greater the power of the laser welding machine, the thicker the welding thickness. Laser welding is about penetration/melt pools. How thick can be welded is also related to the material. 

Laser welding materials can be analyzed based on the following points.

  1. Material
  2. Thickness
  3. Requirements
  4. Welding angle
  5. Rally requirements

Different metal materials have different melting points:

  • The parameter settings of different types of materials are more complicated, and the thermal properties of welding materials will vary with temperature;
  • The difference in the absorption rate of different types of metals to the laser and their temperature-related characteristics;
  • The formation and evolution mechanism of the molten pool;
  • The melting zone and heat-affected zone of the weld during solidification;
  • The formation of laser welding joint defects, welding residual stress, and deformation, etc.
  • However, the key problem can be attributed to the impact of material performance differences on the microstructure and macroscopic properties of the weld;

The formation and evolution mechanism of the molten pool, as well as the formation of welding defects and residual stress during the solidification of the molten pool.

Is laser welding related to the thickness of the sheet?

The depth of laser welding is related to the performance of the material, of course, it also includes the thickness of the material. It is certainly impossible to use the same parameters for welding carbon steel and titanium.

For example, welding: 2mm thick stainless steel plate requires penetration. The finer the weld, the better. It is recommended to use 1000W fiber laser welding, the speed can reach 1m/min or more, 500W is also possible but the speed is slower.

For example, welding: 500W laser welding is used to weld 3mm thick stainless steel plates. One-sided welding can penetrate 1.5mm thick materials. If both sides are welded, each 1.5mm, this 3mm thick material will be penetrated;

For example, welding: 1000 watts welding of 10mm stainless steel plates can also be welded, and one side can be welded with a weld pool of 3mm. The pulling force of some production ports is not high and can meet the requirements. If the speed is slowed down, the slow welding may be deep enough. 5mm

Hand-held laser welding machines are currently on the market with a wide range of uses. Due to their cost-effectiveness and longevity applications, they are generally recognized by the public. Therefore, the price issue has always been an important point of concern for people. Hand-held laser welding machines are sold at this stage. In addition to the price of cabbage, the foolish operation has become a universal device.

People generally think that the higher the power of the laser welding machine, the better, because the higher power is more expensive than the lower power. In fact, the welding effect of a fiber laser welding machine is not only related to its power but also closely related to its accessories, the production quality of the whole machine, software control system, optical system, and many other factors.
