Laser welding

Laser welding is a highly modern, technologically leading and automated welding process for joining various metals and/or non-ferrous metals. BLS Lasertechnology GmbH supports customers with its long-standing and in-depth expertise in this laser technology.

What is laser welding?

Laser welding – also called laser beam welding / laser soldering- is per definition a welding process in EN ISO 4063 (“Process 52”). The process uses a laser for energy supply and applied for welding in a wide variety of industries. Generally, it requires no filler metal. However, some applications may use welding wire / filler wire or LMD powder depending on the requirements. Furthermore, different shielding gases support the process depending on the application and component.

Laser welding joins metallic as well as non-metallic materials. Possible are: Laser welding of aluminum, laser welding of stainless steel, laser welding of copper or laser welding of titanium. But BLS can also weld various special alloys or materials and reviews any special request.

Due to the strong focus of the energy input, laser welding allows particularly deep and precise weld seams. The precision of the laser minimizes stress in the material and thus avoids distortion in the components. In addition, with a high welding speed and automation of the process, the technology offers efficient and fast processing of large quantities.

CNC-controlled 2D and 3D machines guide the laser along the component. In addition, for large-scale production series, complete automation of welding, including semi- or fully-automatic loading and unloading, is possible.

Laser welding is thus an ideal technology for precise, efficient joining of metallic materials and components. Due to its flexibility, the technology is suitable for prototypes, small, medium and large production batches. It supports a really wide set of interesting applications in a diverse set of industries.

Trust in over 30 years of experience.

With extensive laser experience, BLS supports customers as a contract manufacturer from parameter determination / basic development through prototype production to serial production. A high-performance machine park and different laser types enable an overall optimized service offering. The quality management system and exchange with leading research institutions ensure quality at the highest level.
