The welding process is an ancient technology for the localized joining of metal parts. This process is primarily used to weld steel, aluminum, and cast iron. This process is typically used to melt metals locally by blows, with or without mechanical pressure. A weldment is a component connected by welding. There are several welding processes, including forge welding, resistance welding, spot welding, seam welding, and fusion welding, gas welding, arc welding, and several types of welded joints, including edge weld, butt weld, and fillet weld.
This course provides a comprehensive treatment of the design and analysis of welded steel structures, with emphasis on strength, fatigue life, impact resistance, vibration control, and cost-effective manufacturing. It discusses weldment requirements for machine tools and structural applications, comparing welding with casting, bolting, and riveting in terms of flexibility, productivity, stiffness, and weight reduction. The course explains weldment design methodology, including load identification, system-level analysis, stress and strain evaluation, prototype validation, and quality control.
Fundamental material properties such as yield strength, ultimate strength, modulus of elasticity, shear strength, fatigue strength, and modulus of resilience are examined in detail. Sectional properties—including area, moment of inertia, section modulus, polar moment of inertia, and radius of gyration—are applied to tensile, bending, torsional, and combined stress analysis. The course addresses weld joint strength criteria per AWS guidance and introduces fatigue design tools such as the S–N curve and Goodman diagram. Special focus is given to impact loading, energy absorption capacity, stress concentration effects, damping, and resonant frequency control in welded structures.
