What is the effect of arc voltage in SA (Submerged Arc investigation of the effects of submerged arc

Arc voltage has an important effect on the weld bead shape and the depth of penetration; the precise effect being dependent on the joint preparation. Bead on plate welds and square edge close butt welds have increased bead width and dilution as the arc voltage increases, although the depth of penetration is relatively unaffected ( Fig.1a ).What is the effect of arc voltage in SA (Submerged Arc investigation of the effects of submerged arcArc voltage has an important effect on the weld bead shape and the depth of penetration; the precise effect being dependent on the joint preparation. Bead on plate welds and square edge close butt welds have increased bead width and dilution as the arc voltage increases, although the depth of penetration is relatively unaffected ( Fig.1a ).Variables that Affect Weld PenetrationConversely, as arc length increases, the arc cone becomes wider and the arc is broader. The result is a weld bead that is wider and flatter and the level of weld penetration may increase very slightly. The effect of arc voltage on the bead shape can clearly be seen in Figure 8. Notice also that a very slight difference in weld penetration can investigation of the effects of submerged arc
