LAI’s proven team of engineers and technicians understands how to harness the effectiveness of CO2 and Nd:YAG laser machining to reduce your manufacturing costs. Multiple-head, high-speed laser positioning systems offer cost-effective solutions for your short-run or high-volume manufacturing needs. We offer laser machining using from 30 to 5,000 watts of power and advanced material processing for a variety of high-temperature alloys. Our processes include conventional laser cutting, laser cutting of thin materials, laser clean cutting, five-axis laser machining, laser heat-treating, laser hole-drilling, laser drilling of composites, laser machining of tubes and pipes, laser profile machining and laser welding.

Laser Heat-Treating

Tracks used in heavy machinery are
processed using laser heat treating.

Laser heat treating allows metal to maintain ductility while improving the wear properties of specific areas. The laser transformation hardening process produces a fine martensite grain structure. Precise depth and coverage is controlled by PLC or CNC positioning techniques and beam integration and shaping. A surface coating is added to control and maintain beam absorption for consistent results.

LAI's two 5,000 watt CO2 lasers offer 0.080 inches case depths to Rc 60+ in medium carbon steels, such as 4140, achieving greater hardness and less distortion than induction heat treating processes. We can focus the beam between 1/4 inches and 1 inch wide to customize the process and selectively harden highly localized wear surfaces with virtually no heat distortion.

  • Hardness up to Rc65 in medium carbon steels
  • Case depth up to 0.060 inches
