| description | PURPOSE: To provide a metallic tube, dispensing with the troublesome burring, capable of executing the preliminary chamfering to a plate-shaped body, easy to manufacture and inexpensive. CONSTITUTION: A long plate-shaped body is cold rolled to form a plate-shaped body 10 of a prescribed width while chamfering 2 each edge in the longitudinal direction, and is press sheared to the prescribed length to make a plate 1 having a vertical face part 11 and an inclined face part 12 inclined inward formed on the sheared end face. Then, the plate is located with the chamfered side 2 outside and the plate 1 is bent to the cylindrical shape, and both sheared end faces are joined with each other at the vertical face parts 11 to form an opening recessed groove 13 between the ends, and the laser welding is executed to the recessed groove 13 to form an integrated tube through the mutual welding, Because the molten metal is solidified within the recessed groove between both ends, no projection is made as burrs, no melt-down is made by the laser beam welding, and the finishing process can be dispensed with. |
