[0002] Infrared welding is a heat treatment method based on optical principles. Its principle is to use infrared radiation to heat the surface of the workpiece to a certain temperature so that the materials can be combined. During the infrared welding process, light energy heats the surface of the object to hundreds or even thousands of degrees, causing it to melt, ablate or vaporize, thereby achieving the purpose of welding. Infrared welding is mainly divided into two categories: thermal radiation welding and heat conduction welding.
