PIPE JOINING METHOD BY BRAZING

摘要

PROBLEM TO BE SOLVED: To provide a pipe member joining method by brazing, capable of carrying out stable brazing without causing the running-out of wax on a joint surface.SOLUTION: One pipe member 1 is machined so as to have an external bevel shape in which an inner peripheral edge of a wall thickness part bulges out from an outer peripheral edge. The one pipe member 1 is made to butt to the other pipe member 2 having a flat joint surface orthogonal to an axis while putting wax material containing flux between the pipe members 1 and 2. A butting part is heated to join an end surface of the one pipe member 1 and the other pipe member 2.
