the mean value of relaxed strains have been reported for di ff erent depths of pass through dashed lines. Again, it is clear a ε Rrr variation over the hoop coordinate θ . However, in this case, a common behaviour between data can be observed since ε Rrr slightly increases getting closer to the welding starting point θ = 0 ◦ .
