What is Laser Welding?

The use of a laser welding machine is crucial for modern production methods.

Laser welding is a technique that uses a concentrated laser beam to melt and join materials. This technology uses a laser source, such as a fiber laser or CO2 laser, to generate an intensely concentrated heat source. This allows for connections with minimal thermal distortion and maximum precision.

Advantages of laser welding compared to traditional methods:

• Higher precision: The narrow focus of the laser beam makes very small weld seams possible.
• Less thermal deformation: The low heat input limits deformation of the material.
• Speed: Laser welding can combine high speed with consistent results, increasing production efficiency.
• Versatility: Welding lasers are suitable for a wide range of materials, including steel, aluminum and titanium.

Laser welding machines are designed to provide high efficiency and precision in the welding processes. A laser welding machine enables manufacturers to realize complex designs with high precision.

Seam welding with a laser

Laser seam welding is a process of creating long, continuous joints using a laser beam. It is often used in applications where strength and precision are critical, such as in the automotive industry for the manufacture of car bodies and battery components.

Features of laser seam welding:
