Figure 7. Variation of yield strength at three zones of simi-
lar weld joint.
Figure 8. Variation of BI generated ultimate tensile strength
at different zones of similar weld joint.
using BI approach in different sub zones of similar weld
joint (SS 304 LN base metal, HAZ, and weld zone) fol-
lowing points were concluded:
Yield strength of the heat affected zone SS 304-LN
was found to be higher than that of respective base
metal and weld zone.
Heat affected zone and base metal zone shows almost
similar Ultimate tensile strength. However it was
higher than that of weld zone.
Each subzone of weld joint shows significant differ-
rence in mechanical behavior with respect to each
other. Moreover, the variation of mechanical proper-
ties was found to be negligible throughout within
some zones.
The BI approach was found to be extremely useful in
the situations where it is required to conduct non destruc-
tive mechanical behavior examination, in situ inspection,
and structural integrity assessment of structural compo-
nents. Moreover, this approach is useful in the situations
where less amount of material is available for mechanical
behavior evaluation.
