<p><P>PROBLEM TO BE SOLVED: To provide technique capable of easily and quickly bonding mutual tube materials on a construction job site without using throwaway electrothermal wires or a dangerous solvent and further capable of easily checking conditions of bonding. <P>SOLUTION: For a method for bonding the tube material, when a first resin made tube material 12 and a second resin made tube material 14 are bonded via a resin made joint 10 having transmissibility of laser beams and visible light, a laser attraction body 18 is coated on an outer peripheral surface of respective tube materials 12, 14, and parts of respective tube materials 12, 14 are inserted into an opening part of the joint 10, laser beams L are irradiated from an outer peripheral surface side of the joint 10, to heat the laser absorbing body 18 interposed between inner peripheral surfaces of the tube materials 12, 14, and openings between the inner peripheral surface of the joint 10 and the outer peripheral surfaces of the tube materials 12, 14 are fusion welded by transmission heat from the laser absorbing body 18. <P>COPYRIGHT: (C)2004,JPO</p> |
