T1 - Investigation of solidification cracking susceptibility of type 316L stainless steel during laser beam welding using an in-situ observation technique N2 - This technique is the first to provide a measurement of the full strain field locally in the immediate vicinity of the solidification front. Automatic identification of the cases that can be critical for the solidification crack formation the described procedure of the optical measurement allows the real material-dependent values of critical strain characterising the transition to hot cracking during laser welding processes to be determined. The local critical strain in vicinity of the solidification front has observed between 3.6 and 4.2%.
