The fatigue life of two steels was investigated after weathering for two and six years. The test programme covered constant amplitude testing of the base material (flat, unnotched bar) with different quality of surface (as rolled, sand peened after rolling, and in some cases coated with protective colour and afterwards scratched in the midpart of the specimen) and also two different types of welded joint (butt weld and transverse stiffener) which were produced in two workshops by submerged arc welding and manual arc welding. The specimens were weathered in two locations with typical, industrial type atmosphere for a time of six years. In this paper the results of the unweathered and the weathered specimens are discussed and compared to each other. The tests did not show any significant influence of material, steel maker, quality of surface, location of weathering, workshop or type of welding on fatigue life.
