Laser Applications in Construction Machinery

Laser technology is widely adopted in construction machinery (excavators, loaders, cranes, road rollers, concrete pumps, etc.) across cutting, welding, marking, hardening and remanufacturing processes, enabling high-strength, high-precision and high-reliability production.

1. Laser Cutting (Core Application)

Heavy plate cutting: 6–60mm carbon steel/high-strength steel, 3×12m large-format sheets for frames, booms, track shoes and counterweights.

One-step bevel cutting: 45°–55° bevel formed in one pass, ready for welding, reducing labor and distortion.

3D & tube cutting: Hydraulic pipes, drive shafts, boom links with ±0.1mm accuracy, no taper, nestable cutting, material saving 15%+.

2. Laser Welding (High-Strength Joining)

Structural welding: High-strength steel/aluminum frames, booms, hydraulic tanks with minimal heat-affected zone, low distortion and high weld strength.

Precision components: Radiators, hydraulic manifolds, gearbox housings with tight sealing and zero porosity.

3. Laser Marking (Full-Lifecycle Traceability)

Permanent marking: Frame numbers, QR codes, part numbers on components, wear/corrosion-resistant, ideal for outdoor/mining environments.

Replace manual stamping, 10× efficiency, automated inline marking supported.

4. Laser Hardening & Cladding (Strengthening & Remanufacturing)

Key part hardening: Gears, shafts, bearings, bucket teeth, 2–3× service life.

Remanufacturing: Cylinder bores, worn gears, performance equals new parts, 50% cost reduction, eco-friendly.

Key Benefits

• High precision: ±0.1mm accuracy, consistent edge quality, less secondary processing.

• High efficiency: 80m/min+ cutting speed, 24/7 operation, 30% shorter lead time.

• Cost-effective: Nesting saving, no molds, less labor, 20% cost reduction per unit.

• High adaptability: Compatible with carbon steel/HSS/aluminum/thick plates, ideal for low-volume, high-mix production.
