Weld compsn - for low pearlite, gas-shielded or submerged arc welds

摘要

The deposit is produced using core-filled or solid welding wires and contains, after fusion but without mixing with parent materials, 0.03-0.06% C, 0.30-0.45% Si, 1.6-2.0% Mn, 0.02% each of P and S, and 1.5% Mo, 0.06% Nb, 0.2% V, and 0.03% N. The deposit has a low pearlite content and, by working the cooling weld, a fine-grained structure.
