Select-Arc Inc. released Select 550Ni, an all-position, flux-cored, gas-shielded electrode for welding high-strength, low-alloy steels such as HY-80. Specifically developed to maintain yield strength of 80 ksi and impact toughness at –76 degrees F, it produces minimal spatter emission on CO2 shielding gas. The electrode is for applications typically reserved for SMAW electrodes. Available in a 0.045-in. diameter, it is for large structural fabrication, including lifting equipment, jack-up rigs, shipbuilding and other offshore applications.
