SUBMERGED ARC WELDING CONSUMABLES FOR HIGH TOUGHNESS APPLICATIONS

Iron powder additions to submerged arc weld deposits are used as a method of improving the deposition rate of the process whilst maintaining the demanding levels of weld metal toughness specified for North Sea offshore oil and gas production platforms. The use of microalloyed wires containing titanium and boron for achieving good low temperature fracture toughness properties in high dilution welds is detailed for pipe welding, punch through welding and the welding of thin plates. The use of these wires enables the required levels of weld metal toughness to be maintained whilst using cost effective productive welding techniques.
