Welding method yields leakproof joints
Company: Delphi Automotive
What: Friction stir welding of sealed enclosures and heat exchangers
Innovation: Friction stir welding uses a small, rotating tool that plasticizes the edges of the surface to be welded. This process creates a strong, corrosion-free and leakproof joint for use in harsh engine compartment environments.
