摘要： PROBLEM TO BE SOLVED: To provide friction stir welding equipment which can be suitably used for welding each of the members to be joined that are composed of numerous kinds of materials and that are within a large dimensional range. SOLUTION: The equipment is structured in a manner that a tool holder 38 for holding a joining tool 47 is rotationally driven through a speed-changing means 41 by a rotary driving means 40, that the joining tool 47 is thereby rotationally driven around a reference axial line L1 in alignment with the axial line L11 of the tool, and that an object to be joined 95 is stirred in solid phase and the member 95a, 95b to be joined are welded to each other. In addition, between the tool holder 38 and the rotary driving means 40 that rotationally drives the tool holder, the speed-changing means 41 is interposed and changing the rotational speed of the tool holder 38 makes the rotational speed of the joining tool 47 variable. Further, in this equipment, when the rotational speed of the tool holder 38 is varied by the speed-changing means 41, the torque of the tool holder 38 changes with the varied rotational speed, thereby making the output torque of the joining tool 47 changeable.

摘要： PROBLEM TO BE SOLVED: To provide a holding apparatus which holds the objects to be joined in friction stir joining, and prevents the defect in joining caused by the misalignment of the objects. SOLUTION: The apparatus comprises a base 24 provided on a predetermined position, holding parts 25a and 25b holding the objects 22 to be joined, and a connection part 26 connecting the base 24 with the holding parts 25a and 25b so that the holding parts 25a and 25b can be displaced with respect to the base 24. In the case when a backing member 23 is moved, and the objects 22 are abutted on the backing member 23 till it reaches the set position for subjecting the objects 22 to solid phase stirring, in a state where the objects 22 are abutted on the backing member 23, the objects 22 are moved together with the backing member 23, and the objects 22 can be arranged at supporting positions to which the objects 22 are to be supported. Thus, the phenomenon that a joining tool 21 is abutted on the objects 22 prior to the backing member 23 can be prevented, and the defect in joining caused by the misalignment of the objects 22 can be eliminated.

摘要： PROBLEM TO BE SOLVED: To provide a spot welding system that prevents lateral runout of a welding tool caused by rotation in the case of spot FSW by accessing from one surface. SOLUTION: The spot welding system 10 is composed of an articulated robot 11, an FSW head 12 to be attached to the tip end of the robot arm, a base 13 for holding a workpiece W horizontally, and a controller 14. On the FSW head 12, there are mounted a welding tool 15 and a fixing device 16. The fixing device is equipped with a cylindrical pressurizing member 19 and a spring 18. The pressurizing member 19 is pressed against the surface of the workpiece W by the spring 18 at the time of welding, thereby temporarily fixing the welding tool 15 on the workpiece W. Thus, the lateral runout due to rotary reaction of the welding tool 15 is prevented from occurring. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To perform a jointing operation of a jointed member at high efficiency in a manner that a jointing direction varies by mounting a jointing tool to a rotor which can be rotated around an axial core perpendicular to a jointing part surface of a jointed member and fixed to a specific rotation position under an inclined condition. SOLUTION: A tool supporting member 25 is fixed to a rotor 24 while it is inclined against its axial core by a given angle α. Also, the tool supporting member 25 can be rotated around a Z direction axial core by a motor 28 along with the rotor 24. The tool supporting member 25 is pressed downwards via a main body frame 18 by an air cylinder 34, so that a jointing tool T is pressed to and brought into contact with a jointed member P. As a result, even if plate thickness variation due to manufacturing error of the jointed member P, setting error to a fixed board, or partial deformation on the fixed board face occur, positional relationship between the jointed member P and the jointing tool T is kept approximately constant, for performing good jointing.

摘要： PURPOSE:To perform partial penetration welding such as crater treatment without generating welding defects by performing welding while oscillating an electron beam at different frequencies in the direction intersecting orthogonally with the advancing direction for welding and in the direction parallel therewith. CONSTITUTION:An electron beam welding performs welding by irradiating an electron beam 4 to materials 1 to be welded placed on a conveying table 3 in a vacuum chamber 2 and focusing the beam with a focusing coil 5. The oscillation having the directional component perpendicular to the advancing direction X of a circular shape or the like is applied to the beam 4 by the 1st deflecting coil 6 with such electron beam welding device and the oscillation having the frequency different from the frequency of said oscillation and having the directional component in parallel with the direction X is applied superposedly to said beam by the 2nd deflecting coil 7. Then the inside of the molten pool is vertically and horizontally stirred without confinement of the generated gas therein in the stage of partial penetration welding such as a crater treatment; moreover, the welding phenomenon itself is stabilized and weld defects such as porosity, etc. are effectively prevented. The welding with excellent internal quality is thus accomplished.
