“…The inserts and interlayers used in RSW variants need to be resistive materials so that current can flow through these heating elements to generate heat. The metallic heating elements, however, might be relatively heavy, promote corrosion, or create residual stress that creates cracks in the joints [147]. Magnetically assisted RSW (MA-RSW) produced spot welds with a higher tensile strength compared to conventional RSW; hence, it has been proposed to integrate it with a welding gun [148].…”

Traditional resistance spot welding (RSW) has been unsuccessful in forming quality composite joints between steel– or aluminum–polymer-based composites. This has led to the development of spot welding variants such as friction stir spot welding (FFSW), ultrasonic spot welding (USW), and laser spot welding (LSW). The paper reviewed the differences in the bonding mechanisms, spot weld characteristics, and challenges involved in using these spot welding variants. Variants of RSW use series electrode arrangement, co-axial electrodes, metallic inserts, interlayers, or external energy to produce composite joints. FFSW and USW use nanoparticles, interlayers, or energy directors to create composite spot welds. Mechanical interlocking is the common composite joint mechanism for all variants. Each spot welding variant has different sets of weld parameters and distinct spot weld morphologies. FFSW is the most expensive variant but is commonly used for composite spot weld joints. USW has a shorter welding cycle compared to RSW and FFSW but can only be used for small components. LSW is faster than the other variants, but limited work was found on its use in composite spot weld joining. The use of interlayers in FFSW and USW to form composite joints is a potential research area recommended in this review.

“…These alternative heating elements produce welded joints with superior strength and consistency compared with those produced using carbon fiber heating elements. Recent studies have also investigated the use of carbon nanotubes (CNTs) as heating elements [ 15 , 16 , 17 ] and have reported that welding carbon fiber/PEKK (CF/PEKK) laminates with a CNT web yielded a flexible structure with an impressive single-lap shear strength of approximately 30 MPa.…”

“…Early studies explored the application of resistance heatingbased welding using a carbon fiber heating element to ensure integrity and avoid the introduction of foreign materials within the laminate [9][10][11]. However, owing to issues such as disruption of the reinforcement phase and reduced temperature uniformity-attributable Polymers 2024, 16, 750 2 of 14 to the uneven resistance of carbon fiber heating elements-research pivoted toward stainless steel mesh heating elements [12][13][14]. These alternative heating elements produce welded joints with superior strength and consistency compared with those produced using carbon fiber heating elements.…”

This study investigates the secondary bonding of aircraft skin/stiffener assemblies using press conduction welding with carbon fiber/polyetherketoneketone thermoplastic composites and polyetherimide adhesive. Recognizing the challenges posed by conventional welding methods in maintaining material integrity and uniformity, this research explores an alternative methodology that mitigates these issues while ensuring high-strength bonds. The press conduction welding parameters were selected based on single-lap shear tests and applied in the bonding of skin and omega stiffener components. The temperature range was determined using differential scanning calorimetry. The pressure was held at 1 MPa for 180 s. The welding temperature that produced a high-bonding strength was identified experimentally; these key variables were then used in the welding process of the skin and omega stiffener. By analyzing how the fibers tear and the effectiveness of interdiffusion between the plies, we were able to gain insights into the bonding strength and fractured surface. The findings suggest that press conduction welding provides a viable route for secondary bonding in thermoplastic composite structures, highlighting its advantages in terms of processing efficiency and integrity. This study contributes to the understanding of the mechanical behaviors of bonded joints and underscores the significance of temperature control in the welding process.
