Annealing Annealing is a laser engraving technique used to heat-treat metal surfaces and induce controlled changes in their microstructure, hardness, and mechanical properties without altering their overall shape or dimensions. By applying focused laser energy to the surface of metallic workpieces, annealing softens hardened areas, relieves internal stresses, and promotes grain growth, resulting in improved machinability, formability, and surface finish. Annealing laser engraving processes are widely used in manufacturing, aerospace, and automotive industries to enhance the performance, durability, and functionality of metal components, including gears, bearings, springs, and cutting tools, by imparting desired metallurgical properties and surface characteristics through localized heat treatment and thermal modification. |
