Laser Cladding
Home  Hard-Surfacing, Brazing and Welding   Laser Cladding Equipment and Alloys


Laser cladding is a process that utilizes a laser to metallurgically bond performance coatings to a product’s base material. The process uses the laser to create a shallow melt pool of the base material. A stream of a desired powder is then fed into the focused laser beam as it is scanned across the target surface, leaving behind a deposited coating of the chosen material in a true metallurgical bond between the coating and the base material.

The key advantages of laser cladding are as follows:
  • Wide range of different materials can be placed precisely where desired.
  • Sound welds with virtually zero porosity can be made with precision control which minimizes the amount of finishing required.
  • Little to no distortion, regardless of part size.
  • Greater impact resistance; won’t delaminate or chip off.
  • Cost effective.
Aeromac Thermal provides a range of Wall Colmonoy, USA laser cladding powder and wire alloys for the protection and renovation of critical industrial components. The alloys are used within the Steel, Oil & Gas, Waste to Energy, Aerospace and many other industries. We also provide GTV GmbH powder feeders that have been optimised for laser cladding applications.

GTV Powder Feeder Systems The GTV PF Series of Powder Feeders are an advancement of the PT Twin system which is in use for more than 30 years and has proven itself in the field of thermal spraying. In addition, the feeder is used frequently in laser technology including Laser Cladding and Laser Metal Deposition (LMD) based on its extreme feeding precision - even at low feed rates.

The special plate feeder principle with powder suction guarantees exact and precisely reproducible powder feed rates. The powder feed rate is linearly proportional to the plate speed. For all standard units, there are stand-alone versions, e.g. with own PLC and display. All relevant parameters (such as plate and stirrer speed) are set and displayed using the Siemens display (TP177) in the front of the console. Commands can also be entered via the monitor of the plasma/HVOF controller console. In addition, the standard powder feeder has an interface that can be addressed externally, for example, by a robot.

Available powder feeder models include PF 2/1, PF 2/2, PF 3/3, PF 4/2, PF 4/3, PF 4/4, PF 1/1W, PF 2/2W, PF 3/3W, PF 2/1LC, PF 2/2LC

Typical Specifications:
  • Cabinet with keyboard
  • Siemens S7 PLC
  • Siemens Operating Panel TP 177 (Colour display and touch screen)
  • Float-type flow meters for visual inspection
  • Up to 4 Driven powder feed units with stirrer installation
  • Powder Container volume 1.5, 5 or 0.3 litres upon request (for laser application without stirrer)
  • Different types of stirrers (standard or with pins or small plates) available for the powder feeders in order to adjust the container unit to suit various flow characteristics.
  • Option: hopper heater jackets
  • Option: mass flow controller
  • Option: system on scales (weight loss control)
