Liquid State Welding: Fundamentals and Techniques

This lecture covers the fundamentals of liquid state welding, including arc creation, melt pool formation, and the role of shielding gas. Various techniques such as shielded metal arc welding, MIG/MAG welding, TIG welding, and plasma arc welding are discussed. The lecture also delves into more advanced methods like laser and electron beam welding, as well as aluminothermic welding. Different welding processes, power and energy considerations, and the characteristics of different electrodes are explored in detail.
