WebAug 13, 2024 · Laser welding is a plastic welding process that involves using a laser beam to thaw the plastic. However, the heat is kept below the plastics’ evaporation temperature. Pressure is then applied on thawing, and cooling occurs to strengthen the welded joints. Laser welding is fast and occurs in different ways.
WebNov 7, 2024 · Laser plastic welding uses a precise IR laser beam that is transmitted through a transmissive material and absorbed by an absorptive material. The two materials are held in tight contact with each other and the joint between them heats up and melts as energy from the laser is absorbed. The result is a clean weld with minimal flash. Clamp WebThe thermoplastic materials most used in laser welding are then reviewed and discussed, with focus on both welding parts of the same material and welding parts of dissimilar materials. Subsequently, the several laser welding processes or techniques are discussed.
