Proper selection of electrodes is a key element to improve quality of underwater wet welded joint. Three different types of electrode for shielded metal arc welding SMAW namely E6013 E6019 and E7018 were selected to perform
underwater wet welding of the mild steel ASTM A36 plate. Tension and bending test were carried out according to ASTM 4 and AWS D1.1 5 standards respectively. The yield and the tensile strength of welded joints fulfilled the acceptance
criteria. The weld joint using E6013 and E6019 electrodes have satisfied the minimum criteria of elongation but two specimens of the welded joint using E7018 electrode have failed
. Welded joints using E6013 and E6019 have also satisfied
the acceptance criteria of bending test but have failed when using E7018 electrode. The reason why the welded joint using E7018 electrode has failed to fulfill the elongations and bend test might be due to large amount of fine pearlite phase in the
HAZ that made the welded joint less ductile.
