Weldable attachment mechanisms

A riveted assembly comprising:

• a rivet having a rivet portion, a standoff portion having a shoulder substantially surrounding the rivet portion, and a flange portion having a first side and a second side opposite the first side, the first side being secured to an end of the standoff portion opposite the shoulder and the second side having a substantially flat weld surface configured to facilitate laser welding;
• a first structural member secured to the rivet portion by riveting of the rivet portion, the first structural member bearing against the shoulder;
• and
• a second structural member secured to the substantially flat weld surface of the flange portion by a laser weld and spaced from the first structural member by the standoff portion, wherein movement of the second structural member relative to the rivet in a direction away from the first structural member is blocked only by the laser weld.

A weldable rivet comprising:

• a rivet portion configured to be riveted to a first structural member;
• a standoff portion having a shoulder substantially surrounding the rivet portion to receive the first structural member;
• and
• a flange portion having a first side and a second side opposite the first side, the first side being secured to an end of the standoff portion opposite the shoulder and the second side having a substantially flat weld surface configured to be joined to a second structural member by a laser weld such that movement of the second structural member relative to the rivet in a direction away from the first structural member is blocked only by the laser weld.
