Like traditional welding processes, laser welding aims to join two parts together. However, a CO2 laser will do it better, faster and with greater accuracy. CO2 laser are succesfully used as a heat source for welding operations. The laser beam heats the edges of two part to be processed: heat will melt the material, causing the two parts to fuse where they are contiguous. Its main field of applications is laser welding of plastic polymers. This processing technique can be used, for instance, to hermetically seal plastic bags, or to join together parts that are difficult to join with traditional welding tehcniques due to their layout. This makes laser welding excellent in all those applications where extreme precision is required even at micro-scales. But how is it performed? El.En.'s RF CO2 laser sources coupled with a GioScan (for CO2 laser) laser scan heads, have all the key features to do the job. Beam quality and size, power range, components and components have been engineered to let you achieve great polymer welding results for in the automotive, lcd and packaging industries.
