PROCESS FOR PREPARING TUBE WITH FINE PATTERNS USING LASER BEAM

摘要

PURPOSE: A process for preparing tube with fine patterns using laser beam is provided, which allows to form fine patterns on tube irrespective of diameter of tube. CONSTITUTION: The process comprises the steps of forming fine patterns on thin plate, cutting the thin plate with fine patterns to suitable sizes using laser beam, rolling up the cut plate in the form of tube to fix with jig, followed by making tube form via laser welding, and grinding welding part to be remained on the thin plate in the form of tube with laser.
