Abstract
Many industries nowadays with the development of technology require joints between different types of steel due to its various
benefits such as production of lightweight machine parts, production of less expensive components with acceptable properties, high strength,
acceptable corrosion resistance. One of the dissimilar welding challenges is the joint between martensitic steel P91 and austenitic steel
304H due to the dissimilarities in their chemical, physical and metallurgical properties. In this paper is going to be analysed the best way of
joining the two different types of steel, the proper welding technique, the choice of filler material which according to carbon content can
match only to one of the steels. At the end is discussed if the welding performance can meet the requirements of high-quality weld.
