ALPHA LASER has now realized a special concept for micro welding. A machine which, by its construction and with its special optics and optimized shielding gas, is specially designed to carry out the finest micro welding work.

The Laser AL 50 uses a pulsed Nd:YAG-Laser with a pulsing energy of up to 50 J and a pulse peak performance of 5 kW and is ideal for challenging tasks such as joint welding of thermal elements, front face welding work and mantle-surface welding work on sensor casings.

The laser spot diameter of the laser beam has a setting range of 0.05 – 1 mm, ensuring that the workpiece material is only melted in very locally-defined areas during the joining process. The thermal stress is minimal, so the material is not distorted. The high frequency of up to 50 Hz offers a welding behavior similar to CW welding

A good observation of the welding process is ensured with the 55x magnification.

In line with the AL 50, ALPHA LASER offers a workbench, the AL-Tmicro, fitted with a Z-column on which automatic motion is performed. On the base plate, measuring 60 x 60 cm, there are two Y-linear rails with carriages, on which diverse applications can be affixed and used with high-precision. Both a programmable rotary axis and a micro¬manipulator are available for mounting of workpieces. Both systems support precise fixture and movement of workpieces, providing thus an important pre-requisite for seam work on very small components. A cut-out in the base plate allows for easy feeding of longer workpieces.
