The Laser Welding Process
The LASER, an acronym for "Light Amplification by Stimulated Emission of Radiation," is a device that produces a concentrated, coherent beam of light by stimulating molecular or electronic transitions to lower levels, causing the emission of photons. In Laser Welding, the solid-state laser utilizes a single crystal rod with parallel, flat ends, with each end having reflective surfaces. A high-intensity light source, or flash tube, surrounds the crystal. When power is supplied by the PFN (pulse-forming network), an intense pulse of light (photons) will be released through one end of the crystal rod. The light being released is of single wavelength, thus allowing for minimum divergence.
In the Laser Welding process, 100% of the laser light will be reflected off the rear mirror, and 30 to 50% will pass through the front mirror. The laser light will continue on through the shutter assembly to the angled mirror and down through the focusing lens to the workpiece. The laser light beam used in our Laser Welding Service is coherent and has a high energy content, and when focused on a surface, laser light creates the heat used for welding.
In our Laser Welding Services, both the workpiece and the laser beam are manipulated by means of robotics. During the Laser Welding process, the laser beam can be adjusted to varying sizes and heat intensity, from .004 to .040 inches. The smaller size is used for welding and the larger for heat treating.
