Mobile Laser Welding System (MW)

The "Mobile Welder" modular laser system has been specially designed for deposit welding tasks on large tools up to 25 metric tons.

The "Mobile Welder" has been specially designed for deposit welding tasks on large tools, it ensures maximum flexibility when repairing such items, regardless of size and geometry. Strong, torsionally rigid construction and smooth-running axles guarantee high-precision processing. The unit is mounted on steerable castors for high mobility.

The pivoting and slewing arm can be moved and positioned safely in the transport position. The detachable display simplifies operation of the equipment and the monitoring of laser parameters.

The "Mobile Welder" is available with standard power ratings of 60, 120, 160, 300 ,420 and 500 Watts, but versions with a higher power rating are available if needed to satisfy your specific requirements.


-extended range

-more stable positioning than systems with pivot-joint arm

-Less complex construction than systems with resonator integrated into pivot joint of arm

-very long traverse path

-suitable for transport without risk of damage

The key feature of our high-performance laser-welding systems is their modular design so that every device can be adapted to the specific requirements of the customer. The modular concept enables the systems to be used in a flexible manner for a broad range of applications. It also simplifies maintenance. We additionally offer you special solutions for enhanced accessibility, automation and increase of power.
