Abstract:-Sheet Metal Arc welding is also known as Manual Metal Arc welding (SMAW/MMAW), is an advance arc welding process become a popular choice when a high level of weld quality or considerable precision welding is required. However, the serious issues of SMAW welding process are its moderate welding rate and restricted to lower thickness material in single pass. In this work, autogenously SMAW welding has been performed on 12 mm diameter AISI 1020 mild steel rod without utilizing any filler material. The full perforation welding has been tested for a variety of welding current and scanning speed. In addition, activated flux was used to enhance welding depth. The geometry of the weld globules and the tensile strength of the weld were investigated after the welding had kept up a different gap between the soldering rods. It can be shown that a proper gap is maintained, which provides strength for the entire penetration welding of rod.
