The joining of various parts in engineering applications such as automotive components, aircrafts, medical implants, sensor devices, interconnections etc., are a great concern nowadays. Various types of low melting point fillers, braze and alloys have been also developed but problem of crack generation and failures are not satisfactorily treated. This paper reviews some of the developments in traditional and modern joining techniques in automotive joining and welding. Currently, joining of composites is attracting researchers for weight reduction and economy. There are many practical techniques for joining metals and ceramics to themselves and to dissimilar materials. An overview of various processes of joining metal-metal, ceramic-metal and composites, factors affecting joining and approaches used to improve the brazed joint structures are presented here. In addition, new modifications in welding and brazing processes are outlined for further directions.

Ultrasonic welding is one of the most common methods for joining the polymer parts. It provides a rapid joining with a proper strength. Ultrasonic welding is also considered as a clean joining. This method is widely used in joining of thermoplastic parts. But, in order to weld the thermoset parts, a coupling layer shall be incorporated. This method occasionally is perfect because of voids and improper adhesion between to welded parts, leading to significant weld strength reduction. Consequently, application of a kind of NDT method could be useful for quality assurance of these parts. In this paper, active IR thermography is employed to nondestructively test of ultrasonically welded Glass Fiber Reinforced Plastics (GFRP). In order to study the weld microstructure, SEM analysis is performed. The results indicated that the IR thermography is capable to detect the existence of some defects in the welding zone. The Lap-shear tests indicate that the dimensions of the defect reduce the weld strength, significantly.

“…Carbon fiber reinforced thermoplastic (CFRTP) is increasingly favored by automobile and aerospace industries due to its superior mechanical properties (high specific modulus and specific strength), good weldability, short production cycle and potential recyclability [3][4][5]. As a promising joining method for CFRTP, ultrasonic plastic welding (UPW) has the advantages of high efficiency, energy saving, easy to operate and convenient for in-situ monitoring [6][7][8][9]. In recent years, the development of ultrasonic sequential welding and ultrasonic continuous welding has greatly promoted the application of ultrasonic welding technology in the assembly of large CFRTP parts [10][11][12].…”

Ultrasonic plastic welding (UPW) is a promising method for joining carbon fiber reinforced thermoplastic (CFRTP). The interface temperature determines weld quality to a large extent. This paper numerically analyzes the contact behavior and temperature characterization during welding using harmonic balance method (HBM). The simulation and experimental results show that amplitude and welding time are important factors determining the interface temperature. Increasing amplitude and welding time can significantly increase the interface temperature. Plunging speed and trigger force have little effect on the interface temperature. For nonlinear contact and heat generation, the results show that there is a certain separation between workpieces and the heat source is mainly friction heat generation in the early stage of welding. With the progress of welding, there is no separation between the workpieces and viscoelastic heat generation begins to dominate.
