Weldability of High-Strength, Low-Expansion Superalloys

superalloys have been investigated using the spot- and mini-Varestraint weldability tests, respectively. Specific alloys evalu ated included Incoloys 903, 907 and 909. Varestraint test results revealed that the relative susceptibility to both HAZ liqua tion and weld solidification cracking in these alloys was 903 < 907 < 909.
