METALLURGICAL INVESTIGATION ON THE SCATTER OF TOUGHNESS IN THE WELDMENT OF PRESSURE VESSEL STEELS – PART I: CURRENT COOPERATIVE RESEARCH (To Purchase Call 1-800-854-7179 USA/Canada or 303-397-7956 Worldwide)
An aluminum-killed C-Mn steel was welded by these welding methods (SMAW@ SAW and TSAW) and their weldment toughness was evaluated by Charpy impact and CTOD tests. Controlling and scattering factors of toughness in the weldment have been studied in the view point of notch location in the welded joint and direction of fatigue precrack (through notch and surface notch).
