Terminology and definitions
Welded components for machines. Processes, definitions and quality rules

In the context of this dossier, which develops in particular the aspects of design, calculation in relation to the in-service behaviour of mechanical parts obtained by welding or related techniques, a logical classification is based on the shape of the assemblies thus produced and gives rise to the following three categories:

• assemblies involving the close-up processing of a solidified metal bead (with the exception of FSW, in which the bead remains solid during processing) along elements arranged and oriented in any way. The resulting bead is a slender, prismatic volume with a generally triangular cross-section. Most of the processes listed in table
