Popis:	The effect of stress-relieving tempering on the mechanical properties of a welded joint of a high-strength low-alloy steel SAE 4130 (0.3% C – 1% Cr – 0.25% Mo) obtained by multipass arc welding with nonconsumable electrode is studied. The steel is quenched and tempered before the welding. An optimum tempering mode providing a good combination of the characteristics of strength, ductility and toughness of the welded joint is suggested.
