Metallurgy and Welding
One-day training course covering all aspects of metallurgy related to welding
This course is designed for technical personnel who routinely deal with welding issues including design, R&D, manufacturing, and quality assurance. The course starts with fundamentals of metals, alloys, and phase diagrams where we look at grains, grain boundaries, and evaluation of phase diagrams. The next section on mechanical metallurgy deals with mechanical behavior of metals including dislocations, deformation, yield strength, hardness, toughness, creep, and fatigue. The section on heat treatment introduces basics of mechanisms for material strengthening through heat treatment including formation of martensite and precipitation hardening. The section on solidification takes the step from equilibrium to non-equilibrium phenomenon typically observed during metal solidification. The section on welding processes gives a brief introduction on the commonly used welding processes. Based on the understanding gained in the previous sections, we will then look at a variety of alloy systems and try to understand how certain alloys behave during welding and why. This section gives you clues on what to do for specific systems and how to avoid typical pitfalls so common in welding applications.
