ALPHA LASER ALM 300 laser welding machine

ALPHA LASER ALM 300 laser welding machine was built in 2007 in Germany by ALPHA LASER GmbH. The machine is used for the precision welding of workpieces that require high accuracy, i.e. moulds, dies, tools and machine parts. The process involves spot fusing of the material by means of a concentrated laser beam with high energy density. This solution makes it possible to obtain highly accurate and robust welds with reduced thermal distortion at the same time.

ALPHA LASER ALM 300 is equipped with a movable work head, which enables convenient operation even in hard-to-reach areas of the workpiece. The operator controls its position in the X,Y,Z axis by means of a joystick located on the machine arm. The welding process parameters are entered from the membrane keyboard panel or by means of a multifunctional foot switch control. The ALPHA LASER ALM laser beam welding machine weighs approximately 320 kg.
