Abstract:
The present disclosure relates to methods for welding aluminum alloy products, and products made from the same. The new welded aluminum alloy products may be produced by abutting a first aluminum alloy component against a second aluminum alloy component, fusion welding a first zone, and fusion welding a second zone. In general, at least one of the first aluminum alloy component and second aluminum alloy component is one of a 2xxx or 7xxx aluminum alloy. Further, the first weld filler wire is generally one of a 2xxx or 7xxx aluminum alloy, and the second weld filler wire is generally one of a 2xxx, 4xx, 5xx, or 7xxx aluminum alloy. The new welded alloy products descried herein generally include a first base portion, a second base portion, and a fusion welded portion.
Abstract:
An apparatus and method for method for joining materials includes a rivet (10) that may extend through a first sheet (26) to be resistance welded to a second sheet (24). The head (14) of the rivet (10) has a cavity (18) and vents (240) allowing adhesive (236) extruded from a pilot hole (28) to be received in the cavity (18) and vented in a direction parallel to the first sheet (26). The rivet (10) is deformed to an hourglass shape that fills the pilot hole (28) and displaces the first sheet (26) into the cavity (18). Rivet (10) dimensions allow for holding with a robotic gripper (1316) that can be withdrawn before welding. Methods of monitoring joint quality include comparing welding parameter profiles and images of good and discrepant joints.
