Hot Cracking Resistance During the Welding of Austenitic Stainless Steels

  • Erich Folkhard


Because of the great variety of possible types of cracks and causes for their formation, the problem of safeguarding against crack formation in welding operations is a highly complex one. A comprehensive survey of the cracking problems associated with the welding of different steel grades, is given by Baker [282] with special emphasis given to the different crack phenomena and the various causes of their formation. A survey of the different types of cracks found and a basic diagram of the temperature for possible crack formation in the welding of steel is also included in DIN 8524, Part 3. Because of their intricate appearance, hot cracks in austenitic welded joints are of particular importance and the literature available on this topic is quite substantial. Borland and Younger [283] compiled a survey of 162 publications up to the year ending 1959 regarding the hot cracking phenomena during the welding of austenitic chromium-nickel steels. In the documentation „Schweißtechnik, Bibliographie zum Thema Heißrisse beim Schweißen“ [284] which covers the years from 1968 to 1978, 81 out of a total of205 papers deal with austenitic materials. Another survey and a classification of hot cracks as they occur in the welding of various steels is supplied by Hemsworth, Boniszewski and Eaton [285]. A comprehensive survey on the present state of knowledge of heat affected zone (HAZ) cracking in thick sections of austenitic stainless steels is given with 91 references by Thomas Jr. [449].
