Final Year Project (FYP)

Let’s looking back the memories when I was at degree time especially during the Final Year Project (FYP).  It’s about one and a half years ago. On that time, I was did my FYP on Gas Metal Arc Welding Process (GMAW) process while my partner (boy) was did his FYP on Flux Core Arc Welding (FCAW) processes..The way to completed our FYP, we repeated from S.Alam to Bangi..Lastly, we completed our FYP ..Thank a lot to my supervisor, partner and parent.. Below, I will share with you about my FYP.

Abstract of FYP

            Gas Metal Arc Welding (GMAW) process is leading in the development in arc welding process which is higher productivity and good in quality. In this study, the effects of different parameters on welding penetration, microstructural and hardness measurement in mild steel that having the 6mm thickness of base metal by using the robotic gas metal arc welding are investigated. The variables that choose in this study are arc voltage, welding current and welding speed.

            The arc voltage and welding current were chosen as 22, 26 and 30 V and 90, 150 and 210 A respectively. The welding speed was chosen as 20, 40 and 60 cm/min. The penetration, microstructure and hardness were measured for each specimen after the welding process and the effect of it was studied. As a result, it obvious that increasing the parameters value of welding current increased the value of depth of penetration. Other than that, arc voltage and welding speed is another factor that influenced the value of depth of penetration. The grain boundaries of microstructure change from bigger size to smallest size when the variable welding parameters changed. The hardness of weld bead is lower than hardness at Heat Affected Zone (HAZ) zone but higher than hardness at base metal.

Steps of welding process using robotic welding

Step 1: Turned on the OTC Almega AII-B4 robotic welding, CO2 gas tank and others equipment that involved. Make sure the diameter of wire electrode is 1.2mm, AWS classification ER70S-6.

Step 2: Setup the parameters into the programming controller.

Step 3: Then, the plate placed on the table workstation before welding process. The direction of welding process from left to right on the plate.

Step 4: After that, the welding process started by the robotic welding.

Step 5: The welding process done on the plate.

Step 6: Total 9 plates with 27 lines of specimens have been weld with different parameters.
