What is laser beam welding?

Laser beam welding is another method of joining two components by fusing the contact area together with laser beams. It involves melting the material in the contact areas by means of heat, which is obtained by applying a concentrated beam of coherent light. This type of welding uses a high energy density beam (approximately 1 MW/cm²), resulting in a small heat-affected zone width and low temperature effects on the structure, as well as rapid heat dissipation and cooling of the weld. The depth of penetration of the material by the laser beam is proportional to power supply, but depends on the location of the beam focus and the welding speed.

Laser beam welding is widely applied in welding of:

• alloy steel
• carbon steel
• high-strength low-alloy steel (HSLA)
• chemically active metals
• titanium
• refractory metals.

Advantages of laser beam welding:

• very good quality of welds
• high precision
• long durability
• highly efficient process
• process cleanliness and ease of maintenance
• possibility to weld thin materials
• possibility to weld difficult-to-weld materials
• possibility of creating any weld shape.

Disadvantages of laser beam welding:

• quite substantial initial investment costs for the company
• high impact of soiling on the quality of welds
• need to ensure high safety standards.

Laser beam welding is becoming more and more common, which translates into a price for the end customer. The laser beam welding process is accurate and repeatable, and the professional parameter settings of the laser head and source ensure top quality and comprehensive services. This ensures that our domestic and international customers receive a safe and reproducible laser beam welding process.
