abstract |
The multiple cut contour method is applied to map longitudinal and transverse components
of residual stress in two nominally identical 50 mm thick electron beam welded Ti-6Al-4V
alloy plates, one in the as-welded condition and a second welded plate in a post weld
heat treated (PWHT) condition. The accuracy and resolution of the contour method results
are directly linked to the quality of the electro-discharge machining cut made. Two
symmetric surface contour artefacts associated with cutting titanium, surface bowing
and a flared edge, are identified and their influence on residual stresses calculated
by the contour method is quantified. The former artefact is controlled by undertaking
a series of cutting trials with reduced power settings to find optimal cutting conditions.
The latter is mitigated by attaching 5 mm thick sacrificial plates to the wire exit
side of the test specimen. The low level of noise in the measured stress profiles
for both the as-welded and PWHT plates demonstrates the importance of controlling
the quality of a contour cut and the added value of undertaking cutting trials. |
