Which method is NOT typically used to attach moldings?

Welding is not typically used to attach moldings in automotive applications. Moldings are often made from materials like plastic or rubber, which cannot be welded effectively. Instead, the preferred methods for attaching moldings include clips, adhesives, and screws.

Clips offer a quick and removable way to secure moldings to a vehicle's body, while adhesives provide a strong bond for a permanent attachment. Screws can also be used for a secure and mechanical fastening of moldings. Each of these methods is suited for the material and application, making welding unsuitable for moldings in the context of non-structural vehicle components.
