RESIDUAL STRESSES IN TURBINE BLADE SHROUD TENONS AFTER LASER OR TIG WELD BUILD-UP
The proposed work is technologically important to reducing operating costs and minimising outage time for turbines operating in the thermal energy generation industry which accounts for 74% of European electricity and 79% of world electricity. It also forms an integral part of a postgraduate University research project. This experiment is relevant to the situation where a localised weld repair is performed on turbine blades, in particular after mechanical damage occurs on blade tips with shroud attachments, during maintenance activities. It will compare the magnitude and orientation of residual strain introduced into steam turbine blades when weld build-up is performed on the blade tip using different procedures. The residual stress distribution obtained with two different weld processes, laser beam welding (LBW) and tungsten inert gas (TIG) welding, and the effect of post-weld heat treatment (PWHT) will be evaluated.
