Data on assessment and exploratory statistical correlation data analysis of sintered Nd:YAG laser welded 2507 duplex stainless steel.

The effect Spark Plasma Sintering (SPS) parameters and Nd:YAG laser welding parameters such as sintering temperature, sintering time, welding power, welding speed, on Vickers hardness mechanical properties of the Weld Zone(WZ) was statistically investigated. Rectangular plates of 2507 Duplex 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 analysis to relate hardness with other predicting variables and show their statistical significance to hardness value of the weld zone.
