Impact of welding current and joint type design on tensile properties of welded mild steel joint by using SMAW

Oil and gas today are being developed in many sectors. Upstream, midstream and downstream. So, throughout the development, one of the major department is facilities and in it, basically welding play an important role for its completion. So, welding is referred to as a mechanical work to combine separate thermoplastics and metals, by inflicting fusion, which is totally different from using low-temperature steel-joining strategies such as soldering & brazing, which the base metal does not melt. In the heavy and small industries, welding is extensively used in fabrication, preservation and restoring the elements of a system and structure. Welding current is the most influencing parameter in process that have full authorities to manipulate the intensity of penetration, fusion and the electrode feed rate. The quantity of heat evolved for the duration of welding relies upon the current used for a given filler wires and dimension of electrode. Therefore, it is critical that an accurate current is used to supply appropriate best of weld and decrease the distortion problems on the activity.
