A sound-damped vehicle panel assembly, such as a dash panel, is attached to a structural member with one or more weld joints. The vehicle panel assembly may include a main panel member, a sound-damping patch, and a sound-damping adhesive layer arranged therebetween, where the patch covers at least a portion of an acoustically active region of the main panel member. The weld joints that attach the vehicle panel assembly to the structural member are preferably located at weld openings formed in the sound-damping patch and/or the sound-damping adhesive layer so that the weld joint can be formed without melting and vaporizing the adhesive during the welding operation, as such an operation would likely require additional ventilation equipment and could impact the quality of the weld joint.

A vehicle panel assembly, comprising: a main panel member contacting a structural member of the vehicle and having an acoustically active region, the acoustically active region is exposed to a sound source, a vibration source or both;a sound-damping adhesive layer contacting the main panel member and having a first weld opening;a sound-damping patch contacting the sound-damping adhesive layer and having a second weld opening that is aligned with the first weld opening, the sound-damping patch covers at least a portion of the acoustically active region; anda weld joint being at least partially surrounded by the first and second weld openings in the sound-damping layer and the sound-damping patch, wherein the main panel member and the sound-damping patch are both rigid metal components, the sound-damping adhesive layer includes a sound-damping viscoelastic adhesive that adheres the sound-damping patch to the main panel member, and the weld joint attaches the vehicle panel assembly to the structural member of the vehicle. 10. A vehicle panel assembly, comprising: a main panel member being attached to a structural member of a vehicle and having an acoustically active region, the acoustically active region is exposed to a sound source, a vibration source or both;a sound-damping layer being adhered to the main panel member and having at least one weld opening, the sound-damping layer covers at least a portion of the acoustically active region of the main panel member;a sound-damping patch being attached to the main panel member and having a weld opening that is aligned with the weld opening in the sound-damping layer, the sound-damping patch covers at least a portion of the acoustically active region of the main panel member; anda weld joint being formed in the weld opening of the sound-damping layer and including material from the structural member of the vehicle and the main panel member without including material from the sound-damping layer, wherein the main panel member and the sound-damping patch are both rigid metal components, the sound-damping layer includes a sound-damping viscoelastic adhesive that adheres the sound-damping patch to the main panel member, and the weld joint attaches the vehicle panel assembly to the structural member of the vehicle. 11. The vehicle panel assembly of claim 10, wherein at least one of the sound-damping layer or the sound-damping patch includes a weld opening that accommodates a plurality of weld joints within that one weld opening. 12. The vehicle panel assembly of claim 10, wherein at least one of the sound-damping layer or the sound-damping patch includes a weld opening that is generally circular in shape and accommodates a spot weld. 13. The vehicle panel assembly of claim 10, wherein at least one of the sound-damping layer or the sound-damping patch includes a weld opening that is generally elongated in shape and accommodates a continuous weld. 14. The vehicle panel assembly of claim 10, wherein at least one of the sound-damping layer or the sound-damping patch includes a weld opening that has a dimensional ratio ranging from 1.2 to 5.0, inclusive, where the dimensional ratio represents an inner dimension (W) of the weld opening divided by an outer dimension (W′) of a corresponding welding electrode. 15. The vehicle panel assembly of claim 10, wherein the structural member is a structural cross member of the vehicle and the vehicle panel assembly is part of a dash panel. 16. The vehicle panel assembly of claim 10, wherein at least one of the sound-damping layer or the sound-damping patch includes a plurality of weld openings that are arranged in a pattern that follows the shape of the structural member of the vehicle. 17. The vehicle panel assembly of claim 16, wherein each one of the plurality of weld openings in the pattern accommodates a weld joint that includes material from the structural member of the vehicle and the main panel member without including material from the sound-damping layer. 18. A method of attaching a vehicle panel assembly to a structural member of a vehicle, comprising the steps of: (a) providing a vehicle panel assembly having a metallic main panel member, an adhesive layer including a sound-damping viscoelastic adhesive and a metallic sound-damping patch, wherein at least one of the adhesive layer or the sound-damping patch includes a weld opening;(b) locating the vehicle panel assembly on the structural member of the vehicle so that the weld opening is aligned with the structural member; and(c) welding the vehicle panel assembly to the structural member of the vehicle with at least one weld joint, wherein the weld joint is located in the weld opening and is formed with material from the main panel member and the structural member without including material from the adhesive layer. 19.
