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.

Description: Abstract: The objective of the current work was to explore the mechanical and microstructural behavior effect of process parameters for dissimilar joints welded with rotary friction welding. The welding was carried out with three different rotational speeds and forging pressure respectively while friction pressure, friction time, forging time, and burn-off were kept constant throughout the process. Rotary friction welding response graph was used to assist on how the process parameter reacts during a certain time. It was discovered that forging pressure and rotational speed were the major parameters that influenced the hardness and bonding at the interface region irrespective of the process combination. The grains in the Thermo-mechanically affected were found to be refined, hence in the heat-affected zone, the grains were deformed.
