摘要

PURPOSE: A micro tube manufacturing apparatus is provided to reduce weld defects of a joint by preventing a tube from becoming distorted and moved using first and second support rolls. CONSTITUTION: A micro tube manufacturing apparatus forms a metal plate(1) into a small caliber tube, and welds a joint portion of a tube through a laser welding head. The micro tube manufacturing apparatus comprises first and second support rolls. The first support roll supports a metal thin sheet firstly formed. The second support roll supports a tube formed into a circular section.
