Future work should expand on these findings by investigating the cyclic performance of dissimilar joints under fatigue loading and conducting detailed microstructural analyses of the weld zones and the HAZ. The development of a time–temperature–transformation (TTT) diagram for Printdur ® HSA would provide deeper insight into its thermal response. Further studies should also explore the influence of di ff erent filler materials, such as G29 9 (1.4337), on weld quality and mechanical performance. In addition, large-scale static tests with optimized AM nodes are needed to evaluate the structural performance of such dissimilar weld joints under realistic construction conditions.
