The base metal used in this study is corten steel, closely confirming to AISI specification. The microstructure of the material exhibits ferrite and pearlite (Fig. 1).15mm thick plate were machined into required dimensions (200mm * 100mm) using cutters and grinding. The direction of welding was normal to the rolling direction. All necessary steps were taken in order to avoidjoint distortion. Low hydrogen ferrite steel (LHF) Consumables were used to fabricate the joints. The chemical compositions of base metal and weld metals were determined using optical emission spectroscopy.
