LASER ABLATION PROCESS CONTROL P/N: 550002

The patented LPC Sensor System is intended for process control during laser beam paint ablation. The sensor system integrates with the scanning head and laser source to provide closed loop control of laser energy to the process. The LPC can be integrated with any industrial Fiber, Nd:YAG, Diode and CO2 laser beam source.

The ablation process is monitored by a sensor(s) (one or multiple) sensitive to different process generated wavelengths. The microprocessor based controller measures the sensor(s) response and adjusts the laser power to match the ablation requirements for the coating under process. This closed loop control activity provides maximum surface ablation while maintaining minimum to zero substrate damage or distortion.

Specifications

The ALE Cut-Weld-Clean handheld laser processing head is a 3-in-1 fiber-laser tool designed for welding, light cutting, and surface cleaning in production environments. Its main advantages are dual-axis beam wobble control, integrated contact-based safety lockout, active cooling of the optical path, and fast tool-less mode changeover.
For welding, stainless steel typically requires lower laser power because of higher absorption and lower thermal conductivity, while aluminum requires higher initial power, pure argon shielding, careful focus control, and suitable filler wire to reduce porosity and cracking risk. Baseline operating ranges cover 1.0 mm sheet and 3.0 mm plate for both stainless steel and aluminum.
Nozzle selection is based primarily on operation type and joint geometry. Welding nozzles are selected for flat seams, lap joints, inside corners, or outside corners and matched to filler-wire size when wire feed is used. Cutting nozzles are selected by sheet thickness and gas-flow requirements, while cleaning nozzles use a wide, open design for non-contact surface preparation.
