Abstract:
Distortion induced by welding residual stresses (RS) is particularly problematic for the assembly of thin structures and is extremely costly. To understand the influence of process parameters on RS and distortion, RS measurements have been performed in 4 mm thick butt welded and fillet welded stiffened plates of a ferritic steel, using the strain scanner SALSA and distortion has been quantified through surface profile measurements at the ILL. The influence of phase changes, plate and stiffener geometry, and welding parameters on the RS and distortion profiles has been determined.
