IR Welding is a new welding technique that has became mainstream over last few years. This process is used on challenging materials and multi-contoured assemblies. These weld joints also result in a high strength weld joint that is hermetically sealed. The two parts to be welded are held in precisely machines tooling plates. Unlike the Hot Plate weld process IR welding uses infrared heat produced from high powered light bulbs. Once the process temperature limit has been achieved the heat source is quickly removed. The two halves of the material are then precisely driven together to allow the joints to solidify.
