The purpose of this investigation is to study the effect of welding variables on bead geometry, fusion zone profile and tensile properties of double-sided submerged arc welding on SS 304 austenitic stainless steel. The individual effect of welding parameters, i.e., welding current, voltage and traverse speed, on bead geometry and tensile properties was investigated. Both microstructural and mechanical characterizations of the weldment were carried out in the present study. It was observed that the operating parameters have significant effect on bead geometry and tensile properties. The double-sided welding effectively enhanced the weld seam ductility. The percentage of elongation is improved by 19.48% to 50.2% for double-sided samples as compared to base material. A comparative study between single and double-sided butt welding was also carried out. For single-sided sample the percentage of elongation is lower than the base material. The percentage reduction in angular distortion of 55.17% is observed with double-sided weld sample as compared to single-sided weld sample.

本研究的目的是研究焊接变量对SS 304奥氏体不锈钢双面埋弧焊的焊缝几何形状，熔合区轮廓和拉伸性能的影响。研究了焊接参数（例如焊接电流，电压和横移速度）对焊缝几何形状和拉伸性能的个体影响。在本研究中对焊件进行了微观结构和力学表征。观察到操作参数对珠子的几何形状和拉伸性能有显着影响。双面焊接有效地提高了焊缝的延展性。与基础材料相比，双面样品的伸长率提高了19.48％至50.2％。还进行了单面和双面对接焊接的比较研究。对于单面样品，伸长率百分比低于基材。与单面焊接样品相比，观察到双面焊接样品的角度变形百分比降低了55.17％。
