Chao, Ming C. (1979). The Effects of Composition on Weld Solidification Cracking in Low Alloy High Tensile Steels. PHD thesis, Aston University.
Abstract
A study was made of the effects of material composition on weld solidification cracking in the TIG arc welding of thin alloy steel sheet. The main points of this study included the effects of - oxygen, manganese, Mn/S and 0/S ratios on the sulphur induced cracking, and the possibility of predicting crack susceptibility based on the material composition. Materials for this study included a series of Fe-Mn-S-0 alloys and a series of SAE4130 experimental steels (both having a 23 factorial design with Mn, S and 0 each at high and low levels), and a number of commercial high tensile steels. The Huxley cracking test was employed for assessing the crack susceptibility of these steels. Oxygen analysis of weld and parent metals was made in order to determine the oxygen pick-up during welding. In addition examination of weld microstructure and detailed investigation of fresh weld crack surfaces were made in order to study the weld crack morphology...
