Laser welding

The advantages of are numerous. The process is non-contact, it produces high tensile strength and hardness, and it is easily automated. These factors make an excellent choice for many applications. If you are interested in learning more about this welding process, keep reading. It is also a viable alternative to traditional welding processes. Listed below are the top benefits of laser welding:

Non-contact process

A keyhole type of laser welding process is an example of this technology. This type of welding process involves creating a vapor capillary, or hollow tube, in the direction of the laser beam. The inner walls of the vapor capillary are reinforced and allow more of the metal vapor to reach deeper layers of the material. Unlike other types of welding, keyhole welds create highly stable connections. This process is ideal for small components with intricate functional features.

High tensile strength

Laser welding has high tensile strength, but there is a limit to its penetration. The laser power and spot size combination can only be controlled so far, and they also have limited effect on the shear load. Figure 4 and 5 show the shear load of different welds produced with varying laser power densities and spot sizes. A comparison of the interface weld width is also provided, as the test specimens were taken at the weld start, mid-point, and end of the weld.

High hardness

In the present study, high-hardness laser welding was used to weld stainless steel. We measured the hardness and interaction times in weld areas of welded and non-welding samples. The resulting welds were of high quality. We measured power densities of up to 1.98 kW/mm2 and interaction times of 0.15s. Welding speed was also evaluated to determine the effect of varying welding parameters.

Easy to automate

Many sheet-metal fabricators are not yet making the switch to automated laser welding, but Trumpf’s new solution might help them make the transition with ease. Although many fabricators still rely on manual welding methods, these methods are time-consuming and expensive. Automated laser welding systems are often large, expensive, and complex to operate. Trumpf’s solution will help them make the move with ease without breaking the bank.


The cost of laser welding machine depends on its functional requirements and the brand name of the manufacturer. In some cases, some of the equipments cost tens of thousands of yuan, while others cost much less. Some consumers also believe that big brands make better quality laser welding machines than smaller companies. However, small companies can also produce quality laser welding machines. After-sales service is another important consideration. Manufacturers should have a good customer service department.
