Investigation of residual stresses in a laser welded pipe by finite element simulations and neutron diffraction measurements
1997 (English)In: The Fifth International Conference on Residual Stresses - ICRS-5 / [ed] Torsten Ericsson; Magnus Odén; Aneth Andersson, Linköping: Linköping University Electronic Press, 1997, Vol. 1, p. 183-188Conference paper, Published paper (Refereed)
Abstract [en]

Finite element analysis and neutron diffraction were used to evaluate the radial, axial and hoop residual strains in a thin walled pipe with autogenous laser butt girth weld. The pipe, 50 mm inside radius and 2 mm in thickness, was made of AISI 304 stainless steel. Laser welding was carried out using a 2700 W laser, with helium as shielding gas. The results from the numerical and experimental methods were compared.
