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.

Options for AL-ROCK:

  • Mobile laser guards
  • Turn-tilt positioner
  • Mirror system and beam splitter
  • Weld fume extraction
  • Mobile working table
  • Mabotic Scan system

Benefits AL-Rock:

  • Mobile system: Self-propelled crawler chassis.
  • All-over temperature supervision by IR: Highest process safety also at cutting edges – heat supply can precisely be controlled.
  • Turn-tilt-table: Maximum flexibility in 3D treatment by robot-guided laser.
  • Double mirror system: Shapes difficult to access can be hardened in a targeted procedure.
  • Mabotic-Scan system: The area to be processed can be captured by scanner before initiating the treatment.
  • Documentation: The entire temperature and power variation can be appended as PDF log.

Benefits of laser hardening:

  • Thanks to low warping, rework cost can be neglected or is even absent
  • Process chain is shortened, as hardening can be carried out after completion of treatment
  • Lowest risk concerning cracking
  • Zones subjected to wear can be localized and hardened precisely following the contour
  • Penetration depth depends on material and amounts to 1.5 mm max., in contrast to nitration
  • Highly flexible, process fits just-in-time delivery

Possible of applications of laser hardening:

  • Bend radii and particular areas of molds
  • Forming and cutting tools
  • Closing edges of dies
  • Impellers and gears
  • Spindle, shaft and worm drives
  • Guiding devices and stop faces

Benefits of laser powder deposition welding:

  • Outstanding process speed
  • High economic efficiency for large areas
  • Low mixture with base material (less than 5%)
  • Reduced warping thanks to low thermal input
  • Excellent accuracy and reproducibility (serial production)
  • Large possibilities for base and filler materials to be combined
  • Homogenous surface structure, not difficult to machine

  • Tools of any kind

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.

A comprehensive range of accessories is available to meet also most specific requirements:

  • Turn-tilt-objective (for ALFlak 900 F with water cooling)
  • AL Flak 900 F also to be equipped with option powder welding deposition welding
  • Powder nozzle and powder conveyor (for ALFlak 900 F)

Mobile FRONIUS equipment for TIG welding: magicWave2200 featuring up to 220 A welding power.

Mobile FRONIUS equipment for MIG/MAG welding:
Model TPS600i with up to 600 A welding power

Thanks to its high welding power, model TPS 600i is perfectly suited for applications in the sectors of heavy steel construction and machine building, as well as for all tasks to be performed by single wire process with extremely high rate of deposition. The welding power source can deliver a welding current of up to A at a welding voltage of 44 V und 60 % duty cycle.

The temperature absorption can be reduced by up to 80%, due to the integrated water-cooled gas nozzle and new geometry of the contact tube. Even after a longer welding sequence, the torch cools down again to room temperature within short delay. Cleaning is simplified by a sophisticated wear part design; this contributes also to reduced expenses for wear parts.

The cooling unit CU 1400i PRO MC has been designed for efficient heat dissipation caused by thermal load arising during high performance welding. An ECO mode is provided offering dynamic control of the cooling circuit with the purpose of saving energy. The pump speed is controlled depending on the temperature in the return line for cooling liquid.

Our new mobile induction plant „Powerduction 220LG“ for induction hardening, brazing, debonding, heating, annealing, solving and straightening of components – supplies continuous heating power of up to 22kW, is equipped with efficient liquid cooling and suitable for many metals including aluminum.

The quick and precise heat transfer acts on the metal component and avoids damaging. Targeted flameless heating precisely on the spot is essential when working in the vicinity of cables, tubes and other objects sensitive to heat, so previous dismantling work can be omitted. The three-phase device has been designed for intense industrial applications. Heating power can be adjusted in steps of 10%.
