What Is Laser Welding and How Does It Work?

Laser welding is a modern metal joining technology that uses a highly focused laser beam with extremely high energy density. Compared to MIG/MAG or TIG welding, it is faster, more precise and almost contactless, making it ideal for high-quality industrial applications.

How does laser welding work?

The focused laser beam reaches temperatures of several thousand degrees Celsius, melting the joined materials and forming a narrow, strong weld.

• Heat conduction welding – for thin materials, shallow penetration,
• Deep penetration welding – deep, narrow welds with high strength.

The process can be fully automated and controlled by CNC systems, ensuring repeatability and consistent quality in serial production.

Advantages of laser welding

• very high precision and minimal heat distortion,
• much faster than MIG/TIG welding,
• clean, aesthetic welds without post-processing,
• easy automation and robotic integration.

Applications

• railings and fences,
• food-grade fittings,
• ventilation and installation systems,
• steel and aluminum structures.
