Abstract: A system for joining a first part and a second part together with a weld structure. The system includes: a welding element configured to form the weld structure between the first part and the second part; and a control module configured to operate the welding element to form the weld structure. The weld structure includes: a first curved end; a second curved end; a connecting portion connecting the first curved end and the second curved end; a first curved crown spaced apart from the first curved end and concentric with the first curved end; and a second curved crown spaced apart from the second curved end and concentric with the second curved end. The first curved end, the second curved end, and the connecting portion are between the first curved crown and the second curved crown.
