Abstract:Ultrasonic welding (USW) is a promising method for the welds between dissimilar materials. Ultrasonic welding by the third phase (USWTP) method was proposed in combination with the formation of a third phase, which was confirmed as an effective technology for polymer welding between the two dissimilar materials compared with the traditional USW. This review focused on the advances of applying the ultrasonic USWTP for thermoplastic materials. The research development on the ultrasonic USWTP of polycarbonate (PC) and polymethyl methacrylate (PMMA), polylactic acid (PLA) and polyformaldehyde (POM), and PLA and PMMA are summarized according to the preparation of the third phase, welded strength, morphologies of rupture surfaces, thermal stability, and others. The review aimed at providing guidance for using ultrasonic USWTP in polymers and a basic understanding of the welding mechanism, i.e., interdiffusion and molecular motion mechanisms between the phases.Keywords: thermal welding by the third phase (TWTP); ultrasonic welding (USW); welding between dissimilar materials; thermoplastic welding technology
