The aim of the present work is to study the evolution of microstructure, texture and mechanical properties during drawing of mild steel wire of type F8Z used in the manufacture of welding electrodes TREFISOUD. It was found that the as received wire has a ferritic-pearlitic microstructure corresponding to an isotopic state (without texture). This microstructure is relatively heterogeneous in the wire section. On the other hand, after strong drawing structure appears relatively homogeneous, throughout the section of the drawn wire. Also the deformation process by drawing causes the hardening of wire as a function of deformation with a reinforcing component of the fiber texture <110> // ND (majority), typical for bcc materials. Characterization methods used in this work is: Optical microscopy (OM), Scanning Electron Microscopy (SEM), the Electron Back Scattered Diffraction EBSD, Vickers microhardness and the tensile tests.

This work provides information leading to the evaluation of the coefficient of friction for various lubricants during the first blow of a double blow heading operation on AISI 1018 steel wire. A Waterbury-Farrel cold heading machine was instrumented so that the total force and frictional force could be evaluated during the first blow operation. The lubricants investigated fell into four main groups: 1) Lubricants, physically or chemically bonded to the wire; this group included zinc phosphate, 2) Lubricants listed in 1) used together with a petroleum based polar oil, SAE 30 [780 SUS at 80° F (167 × 10−6 m2/s at 27° C)], 3) Liquid lubricants of various viscosities employed with the bare wire, 4) Solid lubricants mixed with a non-polar mineral oil [65 SUS at 80° F (12 × 10−6 m2/s at 27° C)], again used with bare wire. The calculated coefficient of friction was used to indicate the efficiency of the respective lubricants. Liquid lubricants either alone on bare wire or with bonded lubricants proved to be the most successful in reducing the calculated μ value; additives appeared to play a minor role. The results indicate that a low cost liquid lubricant used on bare wire has both economic and operational advantages when cold heading mild steel wire.

The localized electrochemical characteristics of the anodic metal within a zinc/steel couple immersed in seawater was investigated using an Wire Beam Electrode(WBE) composed of 9 zinc wire sensors together with 112 mild steel ones. The results showed that potential and current density distributions of zinc wires were inhomogeneous; main anodic area transferred from the zinc wires adjacent to steel wires to those farther away from zinc/steel interface gradually; besides, some zinc wires behaved as secondary cathodes. This electrochemical inhomogeneity of zinc might mainly be ascribed to the dissimilar distance between zinc and mild steel wire sensors, and their surface electrochemical state as well.
