N2 - The purpose of this study was to determine the effect of mechanical properties and microstructure of the welding results using the method of Metal Inert Gas (MIG) with a variation of nickel-based filler and Post-Weld Heat Treatment (PWHT) for Cast Iron FCD 450. The welding parameters used include a current of 150 A, a voltage of 26 Y, a 100% argon gas composition, a 250 °C preheat, and a DCEP polarity with filler variations namely NiFe, NiFe-1, and NiFe-2. Next, PWHT was carried out using a furnace at a temperature of 595 °C with a holding time of 60 minutes, then cooling the furnace to 350 °C, Furthermore it was carried out cooling the air to room temperature. Some of the tests carried out were visual, macroscopic, microscopic, hardness, and tensile tests. The test results showed that welding with NiFe fillers with PWHT treatment had a regular and uniform phase distribution in the microstructure, and the hardness possessed the highest of other fillers, namely 229.86 HY in the weld metal area and 230.74 HY in the HAZ region, and has the highest value of Ultimate Tensile Strength (UTS), which was 283.7MPa
