Welded machine elements – Design and static calculation of welded components

lamellar tearing; arrachement lamellaire

Cracking caused by shrinkage during welding, on wrought material with a high concentration of flattened, unfavorably oriented micro-inclusions.

chamfering; chamfering

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

section class; plasticity class

Numerical index (1 to 4) characterizing the ability of a bent beam section to tolerate the formation of a plastic hinge.

fatigue class

Allowable stress range at 2.10⁶ cycles characterizing a welded detail (or not) of realization conforming to a given quality level and assigned a probability of survival equal to 97%.

Non Destructive Testing; Contrôle Non Destructif

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