Ductile–brittle transition behavior of the heat-affected zone in X80 automated GMAW girth welds
The ductile–brittle transition of the heat-affected zone (HAZ) in an X80 automated gas metal arc welding (GMAW) girth weld was investigated by instrumented Charpy impact testing, fractography, M–A quantification, and EBSD. The 50% energy transition temperature (ETT 50 ) was −48°C...
