Course Description

Welding and joining skills are critical for the development of metal-based products. There is a growing industry need for engineers knowledgeable in joining technology. This theory-based class focused on the metallurgy of welds. You will learn about welding methods, heat input, diffusion, solidification, phase transformation and welding defects. This is NOT a laboratory welding class.


  • Welding Processes
  • Heat Flow
  • Chemical Reactions
  • Fluid Flow
  • Residual Stresses
  • Solidification
  • Phase Transformations
  • Segregation
  • Hot Cracking
  • Partially Melted Zone
  • Heat Affected Zone
  • Advanced Joining Techniques

Learning Outcomes

The student, upon successful completion of this course, will be able to:

  1. Know the pros and cons of joining techniques and be able to recommend suitable methods for various applications.
  2. Identify common welding defects to welding practices and offer mitigation strategies to eliminate the defects.
  3. Understand different solidification modes and constitutional supercooling.
  4. Use a binary phase diagram to quantitatively describe the compositions, phases and microstructures.
