Effect of chemical composition of welding consumable on slag formation and corrosion resistance

Effectiveness of Using Low‐Strength‐Grade Filler Wires for 800 MPa Grade Ultra‐High‐Strength Steels Laser Beam Welds

“…For the same BM and the three filler wires used in this study, the cooling rate was calculated by referring to the welding condition of GMAW applied to the 2.3 mm BM. [ 35 ] As a result, the T 9/3 was 113.5–124.2 s and the cooling rate from 900 to 300 °C was 4.8–5.3 °C s −1 . In this case, the curves of the cooling rate are located between 10 and 1 °C s −1 as shown in the blue line (Figure 11).…”
