Abstract

Abstract: In this paper, the thermoplastic composite resistance welding technology using stainless steel wire mesh as resistance heating element was studied, and the influence of resistance welding process parameters such as material and specification of insulation film, welding power, welding time, welding pressure on welding quality was investigated, which disclosed the multiple correlation and restriction relationship between each parameter. Through process optimization, problems such as edge effect and current leakage in the welding process were solved, and 180 mm long weld with high quality was realized. The results show that when the insulating layer is 0.1 mm thick PEI film and the welding pressure is 2.0 MPa, the single lap shear strength of the welded sample reaches 40.5 MPa, which is higher than the intrinsic value of the material.

Key words: thermoplastic composite, resistance welding, welding process, single lap shear strength
