...surface hardening as a by-product of the heat generated in the cutting process. Peripheral heat damage is controlled in mechanical processes by using coolant and optimizing tooling and cutting speeds. Since laser cutting involves melting and vaporization, the potential for thermal damage to surrounding...

...of lasers and electron beam (e-beam). In the area of manufacturing, lasers are used for drilling, cutting, joining, hardening, surface modification and micromachining. The development of new laser sources, advanced laser optics and control systems offer new opportunities for lasers particularly...

Laser Technique for Plastics Joining Enhances Aesthetics Clear materials can be welded without adding any color A new process for transmission laser welding of both clear and colored plastics is now possible without the use of opaque materials or the addition of unwanted color. The method developed...

...influence these changes, but it is the fusion welding processes that cause the changes. These processes include metal inert gas (MIG), tungsten inert gas (TIG), laser, and electron beam (E-beam). The effects tend to be less severe with laser and E-beam welding than with MIG and TIG welding. Resistance...

...when laser cutting. Tolerances – The feature to feature tolerance on for the laser cutter is +/-.004 " but is typically. held much closer. The smallest cut possible is dictated by the width of the beam or .008 " wide. Material restrictions – Materials have three factors that restrict them from...
