“…Resistance welding is a process where joining the interface of the adherend is achieved by resistive heating generated by passing an electric current. It is necessary to place an additional foreign material like a wire or a braid at the interface of the adherend [26,64]. The resistive heat causes the surrounding polymers to melt, followed by the cooling.…”

“…The welding attributes of thermoplastics aids to the cost-effectiveness of the composite part to be manufactured in an industrial environment from forming until the finishing steps [20][21][22][23]. The most feasible welding techniques available for the fusion bonding of thermoplastic composites are resistance [24][25][26], induction [25,[27][28][29][30][31][32] and ultrasonic welding [16,23,. They behave differently in a way in which the heat is generated at the welding interface.…”

The ultrasonic welding (UW) technique is an ultra-fast joining process, and it is used to join thermoplastic composite structures, and provides an excellent bonding strength. It is more cost-efficient as opposed to the conventional adhesive, mechanical and other joining methods. This review paper presents the detailed progress made by the scientific and research community to date in the direction of the UW of thermoplastic composites. The focus of this paper is to review the recent development of the ultrasonic welding technique for thermoplastic composites to thermoplastic composites, and to dissimilar materials. Different ultrasonic welding modes and their processing parameters, namely, weld time, weld pressure, amplitude, type of energy directors (EDs) affecting the welding quality and the advantages and disadvantages of UW over other bonding techniques, are summarized. The current state of the ultrasonic welding of thermoplastic composites and their future perspectives are also deliberated.

Aim of this paper is to discuss about the in-opposition welding and the ongoing advancement in same zone. Procedure may include current as much as few kilo ampere and voltage of 2 to 12 volts. Weight, current and voltage necessity differ from plate to plate as their thickness and material changes in an opposition welding process there are two anodes made of copper or tungsten or any of their combination. These materials are picked on the grounds that they have high electrical conductivity and they don't twist much when there temperature is raised. Spot welding is a standout amongst the most ordinarily utilized opposition welding in view of prerequisite of welding slender sheets with one another in huge number of modern application for instance downpour mentor fabricating, body of a vehicle and some more. there are a lot more opposition welding forms like crease welding, projection welding, streak welding, upset butt welding, high recurrence obstruction welding, high recurrence enlistment welding. AC is supply is most acclaim out of these three on account of its effortlessness. DC supply can utilized where substantial measure of current is required. in this procedure there are two cathodes one of which is stationary and the other is mobile. Mainly this operation is used in manufacturing industry for welding of various materials for better performance.

Joining large and complex polymer-matrix composite structures is becoming increasingly important in industries such as automobiles, aerospace, sports, wind turbines, and others. Ultrasonic welding is an ultra-fast joining process and also provides excellent joint quality as a cost-effective alternative to other joining processes. This research aims at investigating the welding characteristics of novel methyl methacrylate Elium ® , a liquid thermoplastic resin. Elium ® is the first of its kind of thermoplastic resin, which is curable at room temperature and is suitable for mass production processes. The welding characteristics of Elium ® composites were investigated by optimizing the welding parameters with specially designed integrated energy directors (ED) and manufactured using the Resin transfer molding process. The results showed a 23% higher lap shear strength for ultrasonically welded composite joints when compared to the adhesively bonded joints. The optimized welding time for the ultrasonic welded joint was found to be 1.5 s whereas it was 10 min for the adhesively bonded joint. Fractographic analysis showed the significant plastic deformation and shear cusps formation on the fractured surface, which are typical characteristics for strong interfacial bonding.
