Effects of Process Parameters on SMAW Weld Quality using SK-260-M E6013 Electrodes
Process Parameters Effects on SMAW Weld Quality using SK-260-M E6013
Keywords:Shielded metal arc welding (SMAW), SK-260-M E6013 electrode, welding speed, heat input
Shielded metal arc welding (SMAW) experiments on mild steel (MS) have been conducted by using two NICHIA SK-260-M E6013 electrodes (diameters: 3.2 mm and 2.6 mm). The present research is unique since it not only shows the effects of welding process parameters on the heat input and weld quality, but also determines the optimum current, voltage, and welding speed for a specified diameter of the electrode to obtain a satisfactory weld quality. The authors have shown the results of using different current values and welding speeds and their effects on the heat input and weld quality with the aid of photographs and graphical plots. Surprising results (contrary to literature) have been obtained; which have been scientifically explained and justified. The research findings would enable welding engineers to use correct amperage, voltage, and the welding speed when using SK-260-M E6013 electrodes in SMAW of mild steel.
