The following items have been added to your list


A low hydrogen electrode of AWS E8045-P2 type specially designed for downhill welding circumferential joints in pipelines API 5L X52- X70. Suitable for root pass in higher strength steels subject to welding procedure qualification. The low hydrogen weld metal provides high notch toughness and excellent ductility to reduce the risk of cracking. The electrode has been specially designed to provide excellent striking properties and elimination of start porosity. Productivity is significantly higher than conventional low hydrogen electrodes for welding vertically up.
