Abstract
This invention provides a configuration of a joint that allows a satisfactory welded joint to be formed with reduced deformation of the joint region when two-face structures (panels) are friction-welded end to end. The panels 31, 32 each have two substantially parallel plates 33, 34 and a third member 35 connecting the two plates 33, 34. The end portions of the plates 33, 34 of one panel 32 are friction-welded to the end portions of the plates 33, 34 of the other panel 32. At least one of the panels has a plate 36 at its end for connecting the plates 33 and 34 and has a rigidity to support a pressing force produced during the friction welding.
Claims19
A member adapted to be used in a friction stir welding, comprising:
- a member which is an extruded frame member and has a recessed portion along an end portion of said member,
- said recessed portion opening directed toward an outer side in a thickness direction of said extruded frame member and toward one end direction of said extruded frame member, and having a side face and a bottom face,
- a raised portion projecting to the outer side in the thickness direction, from the outer side of said extruded frame member, and
- said raised portion is a portion adapted to have the friction stir welding carried out therein by inserting a rotary tool therein,
- said extruded frame member being adapted to have another extruded frame member mounted on said bottom face of said recessed portion of said extruded frame member and to have said another extruded frame member abutted thereto,
- with a gap formed between said side face of said extruded frame member and an end portion of said another extruded frame member, and
- wherein said friction stir welding is carried out by inserting said rotary tool in the another extruded frame member in addition to into said raised portion.
A hollow frame member adapted to be used in friction stir welding, comprising:
- a first hollow frame member having a first plate, a second plate which is substantially in parallel to said first plate, and a third plate connecting said first plate and said second plate,
- said first plate of said first hollow frame member having a recessed portion in a side of an outer side of said first plate at an end portion of said first plate,
- said recessed portion of said first hollow frame member opening directed toward an outer side in a thickness direction of said hollow frame member and toward one end direction of said first hollow frame member, and having a side face and a bottom face,
- a raised portion of said first hollow frame member in the outer side of said first plate, connected to said recessed portion and projecting to the outer side in the thickness direction from the outer side of said first plate, and
- said raised portion of said first hollow frame member is a portion adapted to have the friction stir welding carried out therein by inserting a rotary tool therein,
- said first hollow frame member being adapted to have a second hollow frame member mounted on said bottom face of said recessed portion of said first hollow frame member and to have said second hollow frame member abutted thereto,
- with a gap formed between said side face of said first hollow frame member and an end portion of said second hollow frame member, and
- wherein said friction stir welding is carried out by inserting said rotary tool in the second hollow frame member in addition to into said raised portion.
