Several manufacturers consider electromagnetic, or induction, welding a better way to weld highly filled thermoplastics than thermal or friction welding, or using adhesives.
Automakers are often the driving force behind the latest product and process innovations in assembly. Case in point: European automakers have been using flow drilling screws since 1996 to assemble body panels and chassis made of aluminum and thin materials-which continue to gain favor to make cars lighter.
Traditionally, manufacturers have relied on manual welding to assemble high-mix, low-volume products. But, more companies are turning to a new breed of flexible robots, software and controls.
Whether joining two wires together or attaching multiple wires directly to a terminal or assembly, engineers must choose between resistance welding, soldering and ultrasonic welding.
Traditionally, using any material other than metal in the engine compartment was unthinkable. But, that old rule of thumb is changing as many automakers and suppliers use plastic to reduce vehicle weight.
