Abstract
The present research work aims at clarification of the effect of the welding electrode type on the mechanical properties of SMA welded joints of 9%Ni steel plates. Properties of produced SMA welded joints were evaluated using different non-destructive and destructive investigation methods. In comparison with the conventionally used Ni-based welding electrode ENiCrMo-3 (AWS A5.11), an experimentally produced non-conventional ferritic welding electrode with 11%Ni (ENi11-Company specification) has resulted in a better combination of the mechanical properties of SMA welded joints of this steel type for critical cryogenic applications. Besides, a positive economic impact for the experimentally produced non-conventional ferritic welding electrode, due to its lower cost, could be another attractive aspect.
