At the end of this course, the student should be able to:
- Explain modern steel manufacturing technologies and the metallurgic principles behind most strengthening mechanisms used, with emphasis on modern AHSS and HPS steels.
- Evaluate the effects of weld thermal cycles and steel-based metal/filler metal compositions on the resulting fusion and heat affected zone properties.
- Apply hardenability (carbon equivalent type) predictive equations to find minimum preheat and interpass temperatures to avoid hydrogen induced cracking.
- Apply solidification cracking predictions to optimize filler metal composition, dilution and heat input and avoid cracking.
- Apply reheat cracking susceptibility, use predictive equations and simulate weld testing to avoid it.
- Differentiate between and understand the relationship with service-induced fatigue and corrosion-fatigue cracking mechanisms from the above three manufacturing cracking.
- Recognize Fitness for Purpose (FFP) design and service performance concepts and the relationship between metallurgic (pre-existing) cracks on long-term fatigue and brittle failure -- as opposed to plastic collapse and Safety Factor classical concepts.
- Assess the applicability and limitations of steel welding codes such as AWS D1.1, D1.5, API 5L, and ASTM Section IX.
- Perform metallography, optic and electron microscopy.
