also difficult to define the values of magnetic index mlim
for individual RMF components. It is puzzling that the same defects,
located at the same depth in the joint, in some cases give
indications (both when measured from the face and back of the
weld) while in others they do not, cf. joint A. It is probably
decided by the level of postweld stresses at the location of defect
occurrence. The testwasmadeonfragments of steelplates, which
could deform freely after welding. For this reason post weld
stresses occurring in them were smaller than those in rigidly
fixed joints of welded structures. This may be the reason for the
ambiguity and lack of indications. The problem of the impact of
the fixing of the welded components (free or rigid) on the value
