Abstract

This study aims to determine the optimal physical and mechanical properties for MIG (Metal Inert Gas) welded AISI 1010 steel subjected to various heat treatment processes. The heat treatments applied included preheating at 300°C, post-weld heat treatment (PWHT) at 600°C, and a combination of preheating at 300°C and PWHT at 600°C. Testing included chemical composition analysis, deformation assessment, microstructural observation, tensile testing, bending testing, hardness testing, and corrosion testing. The microstructure of the base metal and the heat-affected zone (HAZ) consisted of ferrite and pearlite, whereas the weld metal consisted of Widmanstätten ferrite, acicular ferrite, and grain boundary ferrite. Test results indicated that the welded joint subjected to the combined heat treatment (preheating at 300°C and PWHT at 600°C) exhibited the best physical and mechanical properties compared to the other heat treatment variations. The tensile strength of the joint with the combined heat treatment was 376.15 MPa; this value is 40% higher than that of the other heat treatment variations. Meanwhile, the bending strength of the joint with the combined heat treatment was 1925.16 MPa, which is higher than the values ​​obtained for the 300°C preheat (950.04 MPa) and 600°C PWHT (969.72 MPa) variations. Corrosion resistance values ​​for the 300°C preheat, 600°C PWHT, and combined preheat and PWHT variations were 0.8292 mmpy, 0,8854 mmpy, and 0.6051 mmpy, respectively.
