The wires for ferritic steels are generally copper coated to increase contact tip life, improve electrical conductivity and extend the shelf life.
The welding wire is generally of a composition that matches that of the parent metal and wires are available for the welding of carbon and low and high alloy steels, stainless steels, nickel and copper/nickel alloys. In addition, submerged arc welding may be used for surfacing with corrosion or wear resistant coatings using both wires and flat strips. The wires may be solid or metal cored. Strips may be rolled or sintered..
Submerged ARC Welding Wire
Submerged Arc Welding wire also called SAW wire vary from 1.2mm (‘thin’ wire or twin wire submerged arc) to 6.4mm in diameter and are capable of carrying welding currents ranging from 150 to 1600amps.
