- Description: Abstract: The effect Spark Plasma Sintering (SPS) parameters and Nd:YAG laser welding parameters such as sintering tempera- ture, sintering time, welding power, welding speed, on Vick- ers hardness mechanical properties of the Weld Zone(WZ) was statistically investigated. Rectangular plates of 2507 Du- plex Stainless Steel (DSS) fabricated by SPS were joined by Nd: YAG laser welding process. Linear regression analysis was performed on the data, followed by Pearson correlation anal- ysis to relate hardness with other predicting variables and show their statistical significance to hardness value of the weld zone.The evaluated R 2 which is 49%% was used to mea- sure the closeness of the data to the regression fitted line.
