2. Plastic adaptation of welded joints
2.1 As-welded assembly condition
In the as-welded state, the joint undergoes various modifications that affect it at different levels.
-
Geometric :
overall, as a result of deformations caused by welding (misalignment of components in particular);
locally, due to the presence of a bead (convexity) and its imperfections (gutter, for example).
Metallurgy: the thermal cycle generates structures (ZF, ZAT) whose constituents behave differently from the base metal or alloy (MB), both chemically (corrosion) and mechanically (behavior law).
