Self-propelled. Self-scanning. Exchangeable head.

Large machine components or extremely heavy tools and molds – thanks to this mobile laser robot, hardening and laser powder deposition welding are considerably simplified, as the object in question can remain in place. Mounted on a crawler chassis, the robot moves around the component, always stopping at the position required. We use this system for mobile applications at the site of the client. An adequate tun-tilt positioner can be ordered as well, sometimes required for particular projects for flexible 3D treatment. The laser heads for hardening and powder deposition welding (with supplementary modules) are exchangeable. The AL ROCK machine is equipped with a scan system to register the shapes to be processed, for subsequent data processing and efficient welding or hardening of the desired surfaces according to the requirements.

Laser hardening by AL-ROCK

In free 3D motion, the laser beam precisely traces the shape of the workpiece. This way, hardening of closing edges, grain structures, nubs or single points is really not a big deal. The temperature dependent control of laser power supplies the heat exactly to the spot desired, without applying any excessive thermal load on adjacent zones. For quality control, the process is meanwhile documented, so process safety and reproducibility are ensured.

Laser-powder deposition welding by AL-ROCK

In the course of a laser powder deposition welding procedure, the laser beam first slightly melts the component surface, then a gas stream injects filler metal in the form of powder into the bath. This process generates a metallurgically bonded layer with least possible dilution with the base material (less than 5%), free of pores and cracks. This method is useful for repair or coating of components, to enhance surface properties or upgrade geometrical parameters. Even large damages can be repaired quickly and nearly without trace. The tool afterwards can immediately be reused without any restriction. Design changes are possible as well.

Use laser powder deposition welding for modification of components by wear protection coatings, or repair of damaged or worn items.

CW- or Pulse- Mode. Consistent welding process without repositioning. Self-propelled. Programmable.

Welding positions in complex shapes or in recesses may be extremely difficult to reach. For the ALFlak machine however, this is no problem, as it features a laser arm with large projection. For this reason, the welding process can be carried out in a single sequence without interruptions due to repositioning. Welded seams of up to 500 mm are possible in a single run. For the fiber lasers, power versions of 300W and 1200W are available. The resonators have been milled from solid metal to provide for optimum beam quality. Besides movable objectives, a sophisticated pivotable beam deflection is integrated, so welders can perform their work from a comfortable ergonomic position, with trouble-free access to each welding position anytime.

The rugged high-performance laser systems, originating from ALPHA LASER, are perfectly prepared to carry out complicate joints, nearly impossible to handle by conventional methods – also in direct vicinity of sensitive objects made of plastic and glass. As laser energy and reaction time are precisely controllable, even metals with high melting point and thermal conductivity can be welded in pulse or CW mode. Different metals can mutually be connected as well. Whether for repair, modification or for production of entire series, top quality treatment of sheet metal, aluminum, stainless steel and section steel is out of question.

Mobile Laser Hand Welding Units

Increased speed, maximum user friendliness and a wide scope of applications belong to the major benefits of laser hand welding method, which is currently revolutionizing the industrial market. Compared to well-known TIG welding, it exceeds the speed by factor 4. Users become quickly familiar with the method and are able to deliver good results within short time. Positioning of the laser gun does not give rise to difficulties, even in locations to reach. This extends the scope to highly complex assemblies.

Besides practical points of view, the excellent quality of the resulting seam proves to be an advantage of this method. Warping is considerably reduced -compared to seams produced by TIG welding-, and the optical appearance of fillet welds is enhanced without any negative impact on mechanical properties.

Lower warping thanks to targeted heat input -
Maximum productivity and flexibility.

Only one quarter of the working time usual in a TIG – welding procedure is needed for comparable laser welding. Simply position the lightweight laser gun (0.5 kg) at the required place, no matter if it is difficult to reach. Welding nozzles are selected according to the requirement: Fillet or butt welds, corner welds or outside seams. The concentrated energy input enables homogenous root seams to be produced.

Costs for preparation and rework, e.g. for grinding and polishing, are often no more necessary – this represents an economical advantage over conventional methods.   Furthermore, as the method manages without large heat input, reduced warping contributes to elimination of straightening work normally required.

For various materials and a wide thickness range, laser welding delivers valuable and reproducible results with excellent mechanical properties. Personnel can conveniently be trained without major effort. Even welders with many years of experience are surprised by the results.
Our factory service is looking forward to presenting you the equipment in a live demonstration anytime.
