Abstract
The Shielded Metal Arc Welding (SMAW) is used extensively in different industry segments for different applications, e.g. structural welding, general welding fabrication, etc. Stick electrode is one of the major components of SMAW process. However, end users extensively using these electrodes have reported variable weld penetration and unwanted spattering recurrently during the SMAW process. Concerns have been raised about weld spatter defined as loss of electrode material. Excessive spatter results in productivity loss as unscheduled work stoppage happens due to weld cleanup, repair and rework requirements. Extent of spatter is a major quality issue and a product differentiator. After an elaborate exercise, negligible differences were observed among the electrodes in terms of welding performance issues, e.g. spatter, weld bead profile. Spatter measurement results show that Electrode A produced fewer spatters than Electrodes B and C at almost all current levels. All-weld chemical composition and all-weld tensile properties were also found to be similar for all three electrodes as electrodes were hailed from the same category.
