Abstract
Weldbonding is a combination of resistance spot welding and adhesive bonding. It is a hybrid process that combines the advantages of the two individual processes. There are two techniques for conducting weldbonds: the flow-in and the weld-through techniques. The weldbonding procedure provides many advantages, e.g.: improved crash performance, fatigue behavior and corrosion resistance. The degree of acceptance of weld-bond applications has been increasing, as the process has been understood and its mechanical properties developed. The present chapter addresses both techniques (flow-in and weld through) from implementation to modeling, including analysis and characterization. Practical implications as well as fields of application are also highlighted.
