Welding: friction takes the plunge

Abstract

Examines the development of friction plunge welding, a new technique for joining dissimilar material combinations. Describes the principles of this welding method and gives its advantages over traditional rotary friction welding. Concludes that it provides an alternative method of manufacture for products such as engine valve seats, end connections and cappings and tube to plate transition joints. The new technique also has potential for joining thermoset to thermoplastic materials.
