Description / Abstract:

An investigation on the weldability of a quenched and tempered 9% Ni-steel, using weld simulation and artificial aging to estimate the heat affected zone (HAZ) ductility at cryogenic temperatures is reported in the first part of this paper. A series of large scale tensile tests have also been carried out on 9% Ni butt welds, the results of which are presented in the second part. Charpy-V bars were subjected to various weld simulation cycles and subsequent heat treatments and after notching broken at a range of cryogenic temperatures.
