The structural integrity of the fillet-welded joint with large gap sizes made by semi-automatic CO2 gas shielded welding is investigated to suggest for the improvement of construction quality standards. An allowable limit on the gap size of welded joints is specified in many construction quality standards based on experimental and empirical results from the welded joints made by manual metal arc welding. Mechanical tests such as hardness, tensile, bending and fatigue were performed to confirm the welded specimen’s quality. Macro observation and dye penetrants inspection were performed on the welded specimen face and weld toe area to verify if any defects are present. Obtained S–N curves from experimental results for the welded specimen with large gap present higher performance compared to the fatigue design S–N curves proposed by the International Institute of Welding (IIW) and UK-HSE.
