LASER SYSTEMS FOR METAL PROCESSING

FROM VISION TO INNOVATION WELCOME TO ALPHA LASER WE DEVELOP AND PRODUCE APPLICATION-ORIENTED LASER SYSTEMS THAT ALLOW OUR CUSTOMERS TO WELD, CUT AND HARDEN QUICKLY, EASILY AND PRECISELY. Under its guiding principle From Vision to Innovation, ALPHA LASER has become the leading manufacturer of laser welding devices in skilled trades and small-series industrial production. Since introducing its first mobile laser welding device in 2003, ALPHA LASER has been renowned worldwide as the inventor of mobile laser welding. We cultivate close partnerships with our users to implement new functions in...

LASER WELDING VERSATILE | EFFICIENT | ECONOMICAL WHY LASER? Manufacturing molds and tools can be expensive, and their service life can be shortened by wear, LASERS HAVE VERSATILE USES IN PRODUCTION AND REPAIR, ESPECIALLY IN THE THE FIELDS OF... damage and corrosion. Laser welding and laser hardening can significantly increase the life of molds and tools. Laser deposition welding can also be used to make design changes, so that an old PRECISION ENGINEERING mold will not have to be replaced. Welding precision metal parts Laser systems from ALPHA LASER feature excellent performance and...

THE RESONATOR CLINCHES THE DECISION Did you know that our resonators are milled from a single piece to provide the best beam quality? Sophisticated, rotatable beam deflection and movable objectives ensure you a comfortable work position while reaching any location to be welded.

ALPHA LASER MOBILE SYSTEMS A CLASS IN THEMSELVES LOW SET-UP TIMES | EXTREME FLEXIBILITY Mobile laser welding has become an important branch of laser materials processing, because its advantages are obvious: Repairs and material application can be done on large machine parts or molds and tools weighing tons, directly on site. Thus, with a mobile laser, for example, repairs can be made in injection molding machines or complete mold halves with very little positioning effort. The mobility offers the user enormous flexibility and extremely short set-up times. These advantages provide cost...

Extremely short set-up times allow a vast range of machine components, pressing tools and large molds to be repaired and modified with the ALM at any imaginable location. The ALM’s versatility is impressive. The workpiece can be transported to the laser, or the laser to the workpiece. This ensures mobility within the company or at the customer’s. The ALM is air cooled and requires no additional cooling systyem. Just move the laser to the workpiece, secure the laser area, aim the slim laser arm at the weld, and start welding. The hydraulic brakes fix the laser beam exactly at the desired...

ALFlak MAX AN ESPECIALLY LONG REACH With a laser arm almost 2.80 m long, the ALFlak Max A rotatable laser head, the unique optional turn and tilt offers an especially large movement radius – as a service objective, and various focusing lenses ensure that you provider or mold maker, this gives you even more flexibil- can reach almost any position on the workpiece with the laser beam. The ALFlak Max comes in two versions: with a self-pro- Whether working on pressing tools, large molds or pelled caterpillar track or a model that can be moved machine components, just move the ALFlak Max on its...

OPEN SYSTEMS WORK WITHOUT LIMITATIONS An important criterion for optimal welding results is the stability of the movement system, because exact laser focusing is possible only with high stability. This is why our laser work benches are especially sturdy. During welding, the workpieces can be precisely controlled on 3 axes with the AL-T 500. With the AL-T Basis, the laser head is moved over the workpiece. In addition, there is an optional rotating axis for circular welding. These open systems allow welding of the largest and smallest workpieces, without limitation. ALFlak movement system s...

AL SERIES FLEXIBLE FITTINGS AL series lasers are extremely flexible when it comes to power, laser source and equipment. The AL can therefore be individually configured and optimally adapted to changing requirements. AL series devices work excellently with AL-T workbenches. However, you can also integrate the AL into your existing AL 300 machine assembly. Nd:YAG laser sources are available with 75 to 500 watts of power. Your advantage: The laser power actually gets to the workpiece. TECHNICAL DATA These compact laser welding devices can even perform very laser on all devices. However, the AL...

AL FIBER ONE SYSTEM – 4 POSSIBLE LASER HEADS The AL is now also available with a fiber laser. The fiber source is highly energy efficient. For reproducible welds, output monitoring keeps an eye on the welding process. The AL-F's possibilities range from mobile welding with a laser pistol and video goggles to manual welding viewed through a microscope or fully automatic welding processes observed through a camera.
