Use of optical measurement technique to investigate the hot cracking sensitivity of 316L during laser beam welding

41258 2017 eng lecture 0 -- -- -- Use of optical measurement technique to investigate the hot cracking sensitivity of 316L during laser beam welding This technique is the first to provide a measurement of the full strain field locally in the immediate vicinity of the solidification front. Dependency between the external strain rate and the critical local strain has been observed. The local critical strain in vicinity of the solidification front has observed between 3.6 and 4.2%.
