Engineering Fracture Mechanics, 2015 Friction stir welding (FSW) is a promising candidate for use in pipeline steels because it offers high productivity and sound welded joints. This study presents a fracture toughness assessment of FSW-welded two-pass butt joints, different regions within the joints and tests temperatures (25 °C, -15 °C, -20 °C, -35 °C, -40 °C) were used.
