Abstract
For the evaluation of the solidification cracking behaviour of welded structures, the influence of the external boundary conditions needs to be considered, in addition to the metallurgical aspects. Against this background, the solidification crack formation in a fully austenitic stainless steel under variation of external restraint was examined in this study.
For this purpose, a newly developed hot cracking test (CTW test) was used for the first time, which allows application of a defined tensile load transverse to the welding direction during welding. In addition, the strains and strain rates could be determined with the help of a mechanical-electrical measuring device in the near field of the weld pool. These values were examined both under free contraction and varied external load, i.e. under different constant cross head speeds. The Critical strain and strain rate required for the propagation of macroscopic surface cracks were determined. By means of high speed recording the authors succeeded in correlating strain and strain rate with the relative position of the weld pool. In addition, centreline crack initiation and growth were located.
