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.
Claims15
A hollow frame member adapted to be friction stir welded, comprising:
- a first plate, a second plate substantially in parallel to said first plate, and a third plate connecting a midway of one end side of said first plate and said second plate, and
- one end of said first plate projects beyond an end side of said second plate, and
- said one end of said first plate is a portion in which by inserting a rotary tool therein a friction stir welding can be carried out.
A hollow frame member adapted to be friction stir welded, comprising:
- a first plate, a second plate which is substantially in parallel to said first plate, and a third plate connecting a midway of one end side of said first plate and said second plate,
- one end of said first plate projects beyond one end side of said second plate,
- at a connection portion of said one end of said second plate and said third plate, in a side of an outer side of said second plate, a recessed portion is provided along said connection portion,
- said recessed portion opens directed toward an outer side in a thickness direction of said hollow frame member and toward said one end side of said second plate, and
- a corner portion from said second plate to said recessed portion is positioned at a range in a thickness of said third plate,
- said recessed portion is a portion in which by inserting a rotary tool a friction stir welding can be carried out, and
- said one end of said first plate is a portion in which by inserting said rotary tool a friction stir welding can be carried out.
