What kind of material is submerged arc welding?

Submerged Arc welding is a wire-fed process typically used with carbon steels, stainless steels and some nickel alloys, and it is best suited for materials that are 1/2-inch to 5-inches thick. Its a common misconception that SAW is only for thick metals, however.See all results for this questionWhat kind of gas is used in GMAW welding?Gas metal arc welding (GMAW), also referred to as Metal Inert Gas (MIG), processes use a gaseous mixture opposed to a flux to shield the weld. GMAW welding alloys are available in a wide range of base materials and are supplied in as a solid core electrode or wire feed. The shielding gases used for GMAW vary by composition and bulk concentration.See all results for this questionWhat kind of arc welding is done with tungsten?Gas tungsten arc welding (GTAW) is sometimes referred to as tungsten inert gas welding (Figure 4 ). In this process, coalescence of metals is produced by heating with an arc between the base metal and a nonconsumable tungsten electrode. The tungsten electrode serves only to maintain the arc.See all results for this question

Welding Alloys Selection Guide: Types, Features guide to metals steel and alloys in oil gas industry Submerged arc welding

The base metal refers to the composition of the workpiece being welded. Welding alloys, sometimes referred to as welding electrodes, must be compatible with specific base metals being welded. Typically, welding filler alloys are similar in composition to the base alloys or alloys of the parts being joined. Welding alloys or welding filler alloys forms melt with the base alloys of the parts being joined to fuse the parts together.
