This paper reviews the latest developments in joining technologies for automotive body assembly manufacturing. The recent evolution of Resistance Spot Welding (RSW), which has been predominantly used in automotive body assembly for decades, is reviewed first. Laser Beam Welding (LBW) with growing applications is discussed, too. RSW has been continuously advancing to meet the upcoming challenges of new materials and architectures. With its advances, RSW will probably remain the primary joining process for steel Body-In-White assemblies in the foreseeable future. Compared to RSW and LBW, other types of welding, mechanical joining and adhesive bonding techniques are also concisely evaluated. New welding and non-welding joining processes are increasing their application segments in BIW assembly manufacturing. Among them, LBW is very promising because of its process capability and joint quality proven over 15 years in automotive BIW mass production. This application-oriented review of joining technologies is concentrated on their capability and issues, such as quality, throughput and cost-effectiveness, for automotive body assembly operations. When comparing different joining technologies, three important factors should be kept in mind. First, the advantages and disadvantages are relative and application dependent. Specific applications may have unique requirements and emphases, such as on joint quality or process throughput, to reflect particular conditions and objectives. Second, more detailed and thorough analysis is necessary for an application of the new joining technology. Third, paying much attention to substantial initial cost may be misleading. In order for the new applications to succeed, long-run cost effectiveness and quality should be particularly addressed.
