01
Does Not Melt, Due to Low Heat Input
Comparison at Stellite®6 Claddings
Comparing Plasma Transferred Arc Cladding with Laser Cladding: Stellite®6 Cladded layer of 3mm
Compared with PTA Cladding, Laser Cladding’s penetration depth is only 1/5, obtaining higher purity and higher hardness.
02
Decrease of Distortion Due to Low Heat Input
Laser Cladding on a Hydraulic Pump Component
By using Laser Powder Cladding on a Piping component for hydraulic pumps, cladded layer of low distortion is produced. Additionally, by adjusting the diameter of the laser beam, the cladding width is controlled, causing the required amount of cladding to be cut down
Cladding Material: Stellite® 12 (corrosion and wear resistant Cobalt alloy) / Base Material: SUS630
03
Small area can be cladded by using beam size of φ1mm

Microstructure in the vicinity of the Laser Cladding
Expected Effects
・By using near net Laser Cladding, reduction in post cladding machining volume
・Improvement in performance due to the low heat input and low dilution of Laser Cladding create surface modified layer of high physical properties and high quality.
