This year marks the 40-th anniversary of Professor  Andrzej Fabiszewski’s death (1924–1978). He was a forerunner of the X-ray testing of butt welds in railway bridges in Poland. Professor Fabiszewski spent most of his life in Szczecin. The paper presents results of welded joint tests of 11 railway bridges located in the city of Szczecin. The results can be used  for a new multi-level procedure of load-bearing capacity assessment of bridges in operation.
