Experimental Investigation of Corten A588

This analysis lays emphasis on finding a suitable substitute filler rod for welding weathering steel, such as to eliminate the risk of corrosion. The commonly used filler rod for welding weathering steel is ER70S-6 which is not immune to atmospheric corrosion under wetter conditions and in the presence of stagnant water. Under wetter conditions the ER70S-6 develops more rust by the formation of non-protective rust layers. For the improvement of mechanical, metallurgical and corrosion properties of the weld the parent metal is used as the filler material for welding the weathering steel. The filler wires are cut from the parent material as strips of wire sized 1.2mm. The welded joints are made between two weathering steel of dimensions 150 x150mm with a gap of 3mm between the plates. The Shielding gas used for GTAW welding of weathering steel is 100% Argon. The welds are then cut accordingly for tensile and impact testing using water jet cutting process. The test reviled the best suitable substitute filler rod for the commonly used ER70S-6.The findings are complied according to the mechanical properties found in the welds.

Corten steels are widely used in railway constructions and some structural works due to its high strength to weight ratio and high hardness. The main purpose of the research presented herein was to the fatigue crack growth both in base metal [BM] and in welded region. Recent studies proved that low hydrogen ferrite steel consumables can be used to weld steels, which can give very low hydrogen levels in the weld deposits. Hence, in this investigation an attempt has been made to study the weld consumable and weld process on fatigue crack growth behavior of corten steel joints. Shielded metal arc welding was used for fabrication of joints using LHF consumables. The joints fabricated by process using exhibited superior fatigue crack growth resistance.
