The Laser Hardening Head for Surface Treatment is specifically engineered for laser hardening applications on large-diameter shafts, pipes, tubes, and flat metal surfaces. Featuring a wide-beam design, it offers flexible beam widths ranging from 4 mm to 200 mm, enabling both full-surface and selective area hardening o meet diverse industrial requirements. The laser hardening process requires no quenching medium, relying solely on natural air cooling, which simplifies operation and reduces maintenance costs. Hardening depths of up to 3 mm can be achieved while maintaining extremely lo w distortion, typically controlled within 0.03 mm. The process preserves the original surface roughness of the workpiece, eliminating the need for secondary machining and significantly shortening the overall manufacturing cycle. Ideal for wear-resistant surface enhancement, precision heat treatment, and high-value component remanufacturing, this laser hardening head delivers efficient, consistent, and high-quality results across a wide range of industrial applications.

Ideal for surface strengthening and cladding repair of cylindrical, tubular, and flat components across various industries:
Mining & hydraulic support – External surface reinforcement of cylinder barrels and hydraulic legs in coal mining roof supports.
Steel & metal rolling – Wear-resistant cladding for mill rolls, backup rolls, work rolls, and other frequently replaced parts.
Power transmission systems – Surface performance improvement for crankshafts, drive shafts, main shafts, and other rotating components.
Pipeline & energy sectors – External wall protection for pipes used in oil, gas, chemical, and power generation facilities.
Hydraulic systems – Uniform cladding on plungers, sleeves, and tubular parts to ensure sealing reliability.
Flat or partial surfaces – Targeted cladding on localized flat areas or irregular workpiece surfaces.
Q1: How does the wire-fed design achieve 100% material utilization, and why is this important for internal cladding?
A1: Unlike powder-based systems that lose 10–15% of material due to overspray inside confined bores, this off-axis wire-fed head delivers 100%
material utilization with zero powder loss. Every bit of welding wire is melted and deposited onto the internal surface — significantly reducing
operational costs, especially when working with expensive copper-based, aluminum-based, or titanium-based alloys in deep or narrow bores.
Q2: What is the minimum internal diameter for this wire-fed head, and does it perform well on vertical internal surfaces?
A2: This head is optimized for internal surfaces with a minimum diameter of 180 mm (approximately 7 inches). Its coaxial wire-fed design delivers
excellent vertical deposition performance — a critical advantage over conventional powder-based annular systems, which often struggle with
powder distribution and consistency on non-horizontal surfaces. This makes it ideal for repairing hydraulic cylinder barrels, pipe interiors, and
mining components in real-world orientations.
