Experimental Study on Bead Width Changes of St 52-2 Carbon Steel Welds Produced by Submerged Arc Welding Process

In welding industry, submerged arc welding process (known as "SAW") is recognized as a modern Fusion-Arc Welding Process. This process uses an electrical arc between consumable electrode tip and workpiece (as arc length). The electrode is continuously fed into molten region and this region is protected by a blanket of granular flux during welding process. Due to its special nature, this technology is normally used for flat-position and horizontal-fillet welding position. In this investigation, the relationship between SAW variables and bead width in a type of low carbon steel having 10 mm thickness was experimentally studied. The welding current, arc voltage and welding speed were chosen as welding variables and welding joints were prepared for different values of selected variables. After finishing the welding process, the bead width (W) was measured for any given welding condition.
