Welded machine elements

chamfering; chamfering

Mechanical or thermal operation to geometrically prepare the edges of parts prior to welding.

primary stress; primary contrainte

Stress (normal or tangential) resulting from mechanical loading and therefore unable to limit itself.

secondary stress; contrainte secondaire

Stress (normal or tangential) resulting from a deformation differential (mechanical or thermal) and likely to be self-limiting due to the plastic behavior of the material.

Non Destructive Testing; Contrôle Non Destructif

Physical examination method for detecting a continuity solution in a material. The examination can be :

• such as visual inspection (VT) or color contrast PT (RT),...
