Are Quenched and Tempered (Q&T) Steels Readily Weldable?

The BS EN 10277-5:2008 (old BS 970 Part 3) steels are good examples of these types of steel. Conversely, some Q&T steels have been developed with very low carbon contents and excellent weldability. There is nearly always a heat input limit recommended by the manufacturer for the welding of Q&T steels, as there can be problems with softening of the HAZ when the cooling rate of the weld is slower than that of the quenching (plate) Are q t steels good for welding?Are q t steels good for welding?Thin sections of Q&T steels do not present any significant welding problems. It is easier to match the parent and weld metal properties than for thick, high strength Q&T steels, and the HAZ properties are maintained when the cooling rate is great enough.Are Quenched and Tempered (Q&T) Steels Readily Weldable?(plate) Is there a heat input limit for Q&T steel?Is there a heat input limit for Q&T steel?There is nearly always a heat input limit recommended by the manufacturer for the welding of Q&T steels, as there can be problems with softening of the HAZ when the cooling rate of the weld is slower than that of the quenching process.Are Quenched and Tempered (Q&T) Steels Readily Weldable?
