heal.abstract	The mechanical behaviour and fatigue life of a thin-walled tube joined to a forged component by fillet welding is investigated theoretically and experimentally. The component is loaded by nonproportional random sequences of bending and torsion as measured during operation. The stresses in the welded structure are calculated using finite element analysis. The structure has been meshed following the IIW guideline for application of the hot spot stress approach. The fatigue lifetime of the welded structure is evaluated using the hot spot stresses in conjunction with the critical plane approach to account for multiaxial fatigue. Additionally, a model has been created to calculate fatigue lifetime based on local elastic stresses. The accuracy of the calculations is discussed using corresponding experimental fatigue life results. © 2003 Elsevier Ltd. All rights reserved.	en
