Evaluation of the influence of welding on creep resistance
article
An evaluation is presented of the influence of welding on the uniaxial creep rupture behaviour of some ferritic, martensitic and austenitic creep resistant materials. After a description of evaluation the most reliable figures for the effect of welding will be presented in the form of two parameters. One is the strength reduction factor (SRF) for design conditions. The other is the lifetime reduction factor (LRF) for judging the lifetime of welded components at normal design stresses. Two criteria will be introduced to judge whether the introduction of a stress reduction factor for design of welded components is advisable. The needs for further research in this field are indicated.
