Welding residual stresses are often needed as inputs in fitness for service determinations. This paper collects data on the welding residual stress at the internal surface of girth welds in steel pipes. Comparing the available measurements at the weld centerline, large variations can be noted in residual stress, both in the axial and hoop direction, even on pipes of similar thickness. The range can be somewhat reduced by including the effects of welding net heat input and material yield strength, but at best the range is {+-} 0.4 yield strength. Mechanisms of residual stress formation and estimation techniques are discussed.
