The lightweight design of structural assemblies is an effective approach to property improvement, energy-saving, and environmental pollution reduction. The joining of new and dissimilar materials can fulfill the desired requirements in structural properties and lightweight design, which have gradually become the most extensive materials for structural applications, particularly in automotive, aerospace, railways, and shipbuilding, because of the high strength to weight ratio.

The difficulties and issues in welding and joining new and dissimilar materials need to be solved, while the related highlight should also be welcomed. The viewpoints of structural design, joint formation, microstructural evolution, mechanical properties, and so on need to be investigated, laying the theoretical foundation and providing technical support.
