Metallurgy I

Welding involves various metallurgical phenomena, including melting, freezing, diffusion, precipitation, thermal strains, and shrinkage. If disregarded or misunderstood, these effects can lead to cracking, porosity, or welds with poor properties. Metallurgy I introduces the fundamental concepts required to understand the metallurgical phenomena that affect welding and welded materials. Topics include the characteristics of atoms, the periodic table, chemical bonding, chemical reactivity, the atomic structure of materials, and the properties of metals.

Upon completion of Metallurgy II, students will be able to:

  • Explain the metallurgical phenomena that affect welding and welded materials, including melting, freezing, diffusion, precipitation, thermal strains, and shrinkage
  • Demonstrate an understanding of the characteristics of atoms, the periodic table, chemical bonding, and chemical reactivity, and explain how they relate to metallurgy
  • Analyze and interpret the atomic structure of materials, including crystal lattices, and describe how they impact the properties of metals
  • Identify and apply the appropriate heat treatments and stress relief techniques required to prevent cracking, porosity, or welds with poor properties
  • Discuss the material properties of metals, including ductility, malleability, strength, and toughness, and explain how they are affected by metallurgical phenomena
  • Classify elements based on their properties and describe the characteristics of ionic bonding and corrosion
  • Evaluate the atomic characteristics of the four states of matter and explain how they relate to metallurgical phenomena
  • Apply the fundamental concepts of metallurgy to design, fabrication, or inspection of welded, brazed, or soldered joints
