Course Content (Syllabus)
Introduction, Energy sources for welding (Electrical sources-Arc welding-Resistance welding-Electroslag welding, Chemical sources-Oxyfuel gas welding-Thermit welding, Optical sources-Electron Beam welding-Laser beam welding, Solid state sources-Explosion welding-Ultrasonic welding-Friction welding-Diffusion welding) Electrode, Characteristics of the welding arc, Metal transfer, Heat flow in welding (Distribution of temperature, peak temperatures distribution, cooling rates, solidification rates, weld thermal cycle), The Metallurgy of welding. Weld discontinuities (Cracks, geometric discontinuities, lack of fusion, lack of penetration, inclusions, porosity), Inspection of welds, Welding of metals and alloys.
The course includes hands-on workshops for metal welding using various techniques and microstuctural evaluation of the welds.
