摘要：

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 degrees C, -15 degrees C, -20 degrees C, -35 degrees C, -40 degrees C) were used. Base plates of API-X80 steel 12 mm thick were FSW-welded using two different pass sequences, coincident and alternate directions. The results presented consistently high toughness values down to -20 degrees C for all the assessed notches, which indicates that FSW may be suitable for general pipelines steels applications in that range of temperatures.
