Overview of Methods for Laser Welding Optically Clear Plastics
Abstract The use of laser welding of thermoplastics is increasing in a broad range of applications due to the many advantages it has over competing methods. It can be used in both surface heating and through transmission laser welding. In some applications, it is desirable to laser weld optically clear thermoplastics to each other. This is easier to accomplish with surface … [Read more...] about Overview of Methods for Laser Welding Optically Clear Plastics
