In this study we present an analysis of the evolution of the texture of a mild steel welding rod from the initial state to the welded state. And thus show the effect of drawing on the texture of the welded metal.The analysis of the initial state reveals the presence of a slight texture of the ferritic phase at the periphery. Several hypotheses are emitted but the main cause of the presence of the fiber <110> has not yet been identified.The first deformation leads to the development of the fiber <110> over the entire section of the drawn wire. At this deformation level, the pearlitic phase does not appear to undergo any apparent deformation and the quantitative analysis shows a homogeneous distribution of the texture between the core and the periphery of the wire. After the second deformation, the perlite undergoes a very visible deformation under the light microscope and the fiber <110> becomes more intense in the core than on the periphery of the wire.The examination of the texture of the welded state exhibits another texture composed of three <100>, <110> and <111> fibers whose ratios vary according to the observed angle. The chemical analysis reveals presence of elements of coating of a rod in a matrix of welded metal. It has been found that the drawn state of the rod and the manner in which welding is performed influence the texture of the deposited metal, but their separate effects need to be more inspected.
