AWS A5.23: ECNi1 Submerged Arc Cored Wires Low-Alloy Steel Description AWS A5.23: ECNi1 is a low-alloy composite metal-cored wire electrode for submerged arc welding in high strength applications. it meets AWS A5.23 chemistry Ni1, and is designed for tensile strength levels above 70 ksi. Main Application Single and multiple-pass welding using recommended flux, non-alloyed and fine grain steels, weathering steels (without color matching requirements), low service temperatures, storage tanks, structural components, ship panels ●Structural and bridge fabrication ●Offshore fabrication ●Heavy equipment ●Shipbuilding ●Storage tanks CURRENT Direct Current Electrode Positive (DCEP), Direct Current Electrode Negative (DCEN), Alternating Current (AC) STANDARD DIAMETERS 1/8”(3.2 mm), 5/32”(4.0 mm) STORAGE Product should be stored in a dry, enclosed environment, and in its original intact packaging AWS CLASSIFICATIONS         TYPICAL WELD DEPOSIT CHEMICAL COMPOSITION*     TYPICAL MECHANICAL PROPERTIES*     TYPICAL CHARPY V-NOTCH IMPACT VALUES*     TYPICAL OPERATING PARAMETERS*     Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical depending on the type and thickness of steel being welded. Parameters are provided for informational purposes only. All values are approximate. The optimal voltage may vary (typically ±2 volts) depending on the choice of flux, material thickness, joint design, and other variables specific to the application. Likewise, actual deposition rate may vary depending on choice of flux and contact tip to work distance.
