A study has been carried out to get an idea about the performance of the Tigamajig test which has been developed for the study of hot-cracking. It has been shown that this technique is an excellent method to evaluate the hot-cracking sensitivity of sheet materials with thickness less than 3mm. The results of the Tigamajig tests performed on 16 heats of materials including SUS 310S, Incoloy 800,Hastelloy X and Inconel 600 indicates that the device permits the evaluation of the hot-cracking sensitivity of different types of materials and effect of specific alloying elements on the hot-cracking susceptibility. Good correlation was found between the hot-cracking tendency indicated by the Tigamajig test and actual weldments such as spot welds and MIG fillet lap welds. Metallographic examination indicates that the cracking produced by this device are solidification cracking in the fused metal and liquation and ductility-dip cracking in the heat affected zone.
