Anotace
The aim of the project is the verification of application of progressive welding methods using orbital head in term of their influence on long-term creep behaviour of thermaly loaded thick-walled pipes made of P91 and/or P92 steels. Experimental investigations should verify (confirm or exclude) a possible significant effect of welding to narrow levels of thick-walled tubes/pipes on their final creep behaviour. Further, the possibility of improving long-term properties of tested weldments by new procedures of post-heat treatment of weld joints will be proved.
