Cracks in pressure vessels represent considerable and serious practical prob-lem. These defects can be initiated and enhanced by various factors, such as manufacturing processes, development technology, welding, working condi-tions, and environment. Some of the factors are possible to monitor, thus gain-ing insight into how they can affect crack initiation and prevent it from occur-ring. However, some of them are not possible to predict since they represent a combination of several factors. Presented in this paper is the influence of ex-ploitation conditions and welding on crack initiation and propagation on a spe-cific example involving a starting vessel in thermal power plant. Crack was de-tected in the welded joint after a certain time in exploitation with relatively var-iable working conditions. Effects that could have led to crack initiation and propagation, as well as the potential solutions for avoiding them, were ana-lysed. In addition, a short theoretical review of the demands... which must be fulfilled by pressure vessels is given, with special focus on the effects of weld-ing and the consequences of potential defects.
