Study offers new insights into solidification cracking during welding of steel

Study offers new insights into solidification cracking during welding of steel 30 January 2017 New research led by the University of Leicester in the UK has made a novel breakthrough in understanding how solidification cracking occurs during the welding of steel, an important engineering alloy. In an open-access paper in the journal Scientific Reports , the team proposes that solidification cracks grow by linking micro-porosities in the meshing zone in the solidifying weld pool. This is the first time that researchers have observed solidification cracking in steel and sheds new light on why the alloy may crack during the process. The team used synchrotron X-ray beamline at the European Synchrotron Radiation Facility (ESRF) to observe the crack formation at the real time. Welding is the most economical and effective way to join metals permanently and it is a vital component...
