The effects of spin friction pressure and time on the friction welding between parts of the same material and different materials are discussed. The heat‐affected zone is divided into three regions: the plasticized region (Zpl), the partly plasticized region (Zpd), and the undeformed region (Zud). The tensile fracture morphology has three sections: the non‐plasticized central section (Fud), the plasticized peripheral section (Fpl), and the partly plasticized section between Fud and Fpl (Fpd). Friction pressure (spinning timing): 0.784 Mpa (6 seconds), 0.981 MPa (8 seconds and 10 seconds) in PMMA‐PMMA welding, 0.588 Mpa (10 seconds) in PVC‐PVC welding, and 15.7 MPa (15 seconds) in PMMA‐PVC welding attains better bonding strength, because these parts have larger Fpd and Fpl regions, which have no Fud in the central part.
