In order to ascertain the validity of creep strength reduction factors for welds in real components, creep tests were performed at 600 °C on large specimens made of welded 316 L (N) stainless steel plates. Manual Metal Arc (MMA) welds as well as Tungsten Inert Gas (TIG) welds were investigated. The overall, and in some cases, local deformations of the weld were recorded. The experimental results were compared with two‐dimensional, and in some cases, three‐dimensional finite elements computations using the creep behaviour of the materials as determined by testing small standard specimens. The times to rupture were compared with predictions from design codes and other simplified engineering methods.
