Cladding: Typical Data
Laser
• Direct and fiber-coupled diode lasers
Power
• 1000 W to 6000 W
Beam quality
• 100 to 400 mm mrad
Spot dimensions
• Ø 2 to 4 mm, 2 x 2, 3 x 3 or 1 x 5 mm!
Material
• Tools subject to wear are clad with
powder from hard particles or hard metals
Cladding/Alloying: Principle
Powder and assist gas is fed into the laser
beam coaxially or off-axis
Laser Beam melts powder and eventually
base material
Alloying or depositing of powder onto base
material in one or more layers
Repair or coating in a single process
Spot geometry adapted to parts and
process
Cladding: Options
Cladding optics, different manufacturers (IWS,
Precitec, Balliu and others)
Integrated coaxial powder feeding, transport
gas, shield gas
Integrated sensors for process monitoring
Mechanical shutter, stack management
Cover Slide cassette for cladding optics
Optics with different beam
dimensions and working distances
Supply unit with enhanced programming and
PC-based control
Additional sealing of laser head. Connection
for dry, clean air. Pressure sensor
