RFSSW has multiple applications for the manufacture of automobiles. Here are some examples:
Resistance spot welding is fundamentally difficult to use between aluminum sheets due to the interfacial oxide layer. Weld electrodes also require a high current and suffer from poor durability. RFSSW offers a high-quality, smooth finish surface, and has cycle times similar to resistance spot welding.
Aluminum body structures, and fasteners such as “self-piercing” rivets, are often used to attach secondary components. Not only does RFSSW eliminate the need to supply rivets during assembly, but RFSSW can also accommodate various thicknesses with a single toolset.
