Laser Welding

Laser welding is a welding technique used to join multiple pieces of metal through the use of a laser. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. The process is frequently used in high volume applications. Laser welding has high power density resulting in small heat-affected zones and high heating and cooling rates. The spot size of the laser can vary between 0.2 mm and 6 mm, though only smaller sizes are used for welding. The depth of penetration is proportional to the amount of power supplied, but is also dependent on the location of the focal point: penetration is maximized when the focal point is slightly below the surface of the work piece.

Laser Welding is a versatile process, capable of welding carbon steels, HSLA steels, stainless steel, aluminum, and titanium. The weld quality is high, similar to that of electron beam welding. The speed of welding is proportional to the amount of power supplied but also depends on the type and thickness of the work pieces.

With our 4 kW Fibre laser and 4 kW Diode laser which are both connected to 6-axis robots, high quality fast welding becomes a standard operation for us. Contact us for a quote or a trial.
