Abstract
A new consumable for welding of steels with a yield strength up to 900 MPa is described. The influence of different elements on the mechanical properties has been assessed. A large number of welding trials have been performed to evaluate the influence of process parameters like heat input, interpass temperature and welding position. In general, the weld metal tolerated variations in both interpass temperature and heat input without major changes in mechanical properties. Welding in 3G position gave a somewhat reduced impact toughness, which may be due to dilution from the base material. Some unexpected variations in yield strength was noticed.
