Notes:
This study was carried out on the development of the evaluation method for solidificationcracking susceptibility of Inconel600/SUS347 dissimilar weld metals during laser welding. Somedissimilar weld metals which have different ratios of Inconel600/SUS347 were prepared by TIGwelding and then were remelted on the U-type hot cracking tester by laser. Solidification crackingbehavior during hot cracking test was observed by a high speed camera and the dynamic strain,close to the solidification crack, was evaluated. It appeared that local critical strain, for the initiationof solidification crack, was obtained by this strain measurement method. So the solidificationcracking susceptibility could be directly evaluated based on the critical strain for different dissimilarjoint. By using this method, it was discovered that solidification cracking occurred most easilywhen the ratio of Inconel600/SUS347 is 40%/60%, in the case of the Inconel600/SUS347 dissimilarlaser welded joints
