From: Initiation and growth kinetics of solidification cracking during welding of steel
Results of in situ radiography analysis, showing (a,b) the initiation of solidification crack at 0.134 s of bending with a true bending strain of 3.1%. Crack initiates trailing the welding electrode by 2.69 × 10−3 m at 1.45 × 10−3 m sub-surface, (c,d) crack observed at mid-point of test, (e,f) the end of solidification cracking at 0.832 s of bending and a true bending strain of 9.1%.
