Lecture
This lecture covers solid state welding techniques such as friction welding, ultrasonic welding, and friction stir welding. It explains the principles, advantages, and disadvantages of solid state welding, as well as different weld geometries. The lecture also delves into specific processes like friction depositing and wire bonding in electronics. Additionally, it discusses the applications and physical aspects of explosion welding, as well as forge welding techniques like co-drawing, co-extrusion, and co-rolling. The importance of diffusion welding, its variants, and the influence of intermediate layers and atmosphere are also explored. The lecture concludes by emphasizing the significance of solid state welding in joining dissimilar materials and its applicability to both large and small parts.
