摘要： PROBLEM TO BE SOLVED: To provide a rotary frictional joining method, in which one member is held and rotated in the radial direction thereof without grasping it and which can eliminate the need to carry out positioning of the member in the rotation direction.
SOLUTION: This rotary frictional joining method comprises, while rotating one member 12, 41 around an rotation axis O, pressing and joining the member against the other member 11 in parallel to the rotating axis O. In this case, a protrusion part 131c, which has been formed in a transmission mechanism 13 for transmitting rotary power to the one member 12, 41 and has been protruded toward the one member 12, 41 side in parallel to the rotating axis O, is bitten into the one member 12, 41.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method capable of easily mass-producing a defect-free and highly reliable pipe assembly formed by fitting a valve to a pipe.
SOLUTION: In this manufacturing method, an opening 4 is formed by recessing a part of the side face 2 of the pipe 1 without completely punching out the part thereof. The valve 20 is installed so as to cover the opening 4. The portion 6 of the pipe 1 recessed for forming the opening 4 remains as a part of the pipe 1, and any defect does not occur when the opening 4 is opened. Thus a step of removing and checking a defective portion can be eliminated, and the highly reliable pipe assembly can be provided with a lower cost.

摘要： PROBLEM TO BE SOLVED: To provide a method where the hole part on the side of a sheet member can be worked by a simple method having reduced working stages, and also, the tip part of a shaft member can be satisfactorily friction-welded to the hole part of the sheet member. SOLUTION: A straight through hole 2a is formed as a hole part provided in a sheet member 2 beforehand further, a shaft-like member 1 is composed of a metallic material having hardness higher than that of the sheet member 2, further, a tapered part 1a is formed at the tip part of the shaft-like member 1 beforehand and, in a state where the tapered part 1a of the shaft-like member 1 is fitted in the through hole 2a of the sheet member 2 and is pressure contact thereto, the shaft-like member 1 and the sheet member 2 are relatively rotated, and the tapered part 1a is integrally friction-welded to the inner circumferential wall of the through hole 2a.

摘要： PROBLEM TO BE SOLVED: To provide a joining method (friction welding) that can enhance joining strength as well as preventing falling of flash generated in joining.
SOLUTION: A receiver 1 is composed of a tank body 2 having an opening and a cap 3 blocking this opening of the tank body 2, while the tank body 2 and the cap 3 are joined by a friction welding method. On the joining face of the cap 3, a projection 4 protruding to the tank body 2 is installed over the entire periphery. This installation of the projection 4 enables uniform joined state to be obtained over the entire periphery as well as improving pressure withstanding strength. In addition, inside the projection 4, there is provided a skirt section 5 forming a bag-like flash reservoir 6, storing/holding the flash generated at joining and preventing the flash from falling into the receiver 1.

摘要： PROBLEM TO BE SOLVED: To dispense with a process for removing punching scraps and chips and joining components such as a sight glass to a refrigerant pipe without using a flame. SOLUTION: A drill 3 is rotated while press-contacting with the refrigerant pipe 1 by a prescribed pushing pressure, plasticity is imparted to a contact part by a frictional heat generated in the contact part of the refrigerant pipe 1 with the drill part 3 to drill a hole, and the component 2 such as the sight glass is joined in the hole by friction welding. Different from drilling by a press working, no large pushing pressure applied to the refrigerant pipe 1 and the working time is short, approximately 10 seconds. Even if there is nothing of high rigidity for retaining the shape of a core metal, etc., this constitution can prevent the refrigerant pipe 1 from being largely deformed. Different from the press working and a drilling machine working, no punching scraps and chips are produced in the drilling working so as to dispense with a process of removing the punching scraps and chips.
