100-Series Compact Wire-Fed ID Laser Cladding Head

100-Series Compact Wire-Fed ID Laser Cladding Head

The 4-Inch Coaxial Wire-Fed Laser Processing Head is a reflective off-axis wire feeding system designed for narrow internal surfaces with diameters ≥100 mm. It supports deposition of various wire materials including steel and copper with up to 100% material utilization. The head can be integrated with robotic arms for vertical and complex curved-surface cladding.
With low heat input and minimal thermal impact on the substrate, it produces low-distortion, smooth cladding layers, making it ideal for small-diameter, high-precision internal surface remanufacturing and repair.

FAQ

Q1: What is the minimum internal diameter this 4-inch coaxial laser processing head can access?

A1: This internal cladding head is specifically designed for narrow internal surfaces with a minimum diameter of 100 mm (approximately 4 inches). The reflective coaxial powder feeding system with four-way powder

distribution ensures stable deposition even in confined borespaces, making it ideal for high-precision remanufacturing and repair of small-diameter hydraulic components, pipe interiors, and mining bushings.

Q2: How does this internal cladding head prevent distortion on small-diameter or thin-walled components?

A2: The 4-inch coaxial head features low heat input design with minimal thermal impact on the substrate, producing low-distortion cladding layers with excellent surface flatness. This is critical for maintaining tight

dimensional tolerances on small-diameter internal components such as cylinder barrels, plunger bores, and precision hydraulic parts — where excessive heat could cause warping or loss of fit.
