Abstract

The characterization and properties of TMCP EH36 high strength steel fabricated by the flux copper backing (FCB) one-side SAW process with a high weld heat input of 190KJ/cm were studied. The mechanical properties of the FCB welded joint was tested. The structural characteristics and microstructural features of the FCB welded joint were analyzed using optical microscope (OM). The microhardness distributions along the cross section of the FCB welded joint were studied to figure out the details of the weld softening phenomena. The electrochemical tests were carried out in the three-electrode system to analyze the electrochemical behavior of the welded metals (WM). The symmetrical heat affected zone (HAZ) structure and uniform WM microstructure of tiny acicular ferrites were revealed.
