Abstract
A joining process and friction welded structure is disclosed, including a first member with a conoid recess, and a second member with a second conoid tip that is friction welded to the recess in the first member. One, or both, of the conoids may be a non-spheroid, such as a paraboloid. In addition, the conoid recess may have a vertex angle that is greater than a vertex angle of the conoid tip.
Claims10
A friction welded structure comprising:
- a first member having a conoid recess, the conoid recess having a surface defined by points of a first conic section rotated about an axis of the first conic section, the conoid recess having a first vertex angle;
- and
- a second member having a conoid tip, the conoid tip having a surface defined by points of a second conic section rotated about an axis of the second conic section, the conoid tip having a second vertex angle, the second vertex angle being no greater than the first vertex angle, the conoid tip being friction welded in the conoid recess.
A method for joining members together, the method comprising:
- providing a first member having a conoid recess, the conoid recess having a surface defined by points of a first conic section rotated about an axis of the first conic section, the conoid recess having a first vertex angle;
- providing a second member having a conoid tip, the conoid tip having a surface defined by points of a second conic section rotated about an axis of the second conic section, the conoid tip having a second vertex angle, the second vertex angle being no greater than the first vertex angle;
- and
- friction-welding the conoid tip in the conoid recess.
