Steel Sleeve Repair Welding on Carbon Steel: Intermetallic Compound (IMC) Formation Based on MIG Welding Quality

Steel sleeve repair usage has increased throughout the world, especially in the oil and gas field. Therefore, the efforts to find the perfect parameter to preserve the steel sleeve repair welding parameter. The aim is to determine the improved MIG welding parameter that enhances the weld quality at the steel sleeve joint by using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDS) to validate the data of the project. The Vickers microhardness test was done to determine the strength of the weldment zone, IMC layer and steel base zone. The steel sample must go through a cutting, grinding, polishing, and etching process. The most preferred finding is the sample B welding parameter which shows the improved microstructure and medium-range strength compared to the other parameter. Finally, the heat input is the most significant component to determine the welding quality because of the microstructure reaction with the welding current.
