Mechanical and Microstructural Properties of GMAW Welded Ferritic AISI 1080 Carbon Steel (UNS G10800)
摘要
Finding appropriate connecting methods for the widely used AISI 1080 Carbon Steel plates across numerous sectors can be challenging. When ferritic carbon steels like AISI 1080 are joined, coarser grains are formed in fusion zone, reducing toughness and ductility of metal assembled. To address this, a controlled and well-established welding process is required. With its distinct benefits over other welding processes, the advanced robotic GMAW welding process is considered to be the optimum solution to weld a UNS G10800 Ferritic AISI 1080 Carbon Steel. Mechanical and microstructural properties of welds are examined as part of the examination. Weld metal (WM) has a greater tensile strength (TS) than both the base material and the heat-affected zone. The lowest measured hardness of (170 HV), or 74.88% of the weld metal declared hardness, was found in the base metal, according to the results of the hardness tests. To do microstructural analysis, micrographs of the WM, HAZ, and BM are taken and examined. These assessments offer fascinating details about the characteristics and behaviour of the material during the process of welding.
