Ultrasonic welding (USW) is a solid-state welding process where two components are joined by applying high-frequency oscillatory shear stresses while under modest clamping force. This procedure, which is frequently employed in lap welding (as shown in Fig. below), breaks off surface coatings and permits close contact between the components, forming a strong metallurgical bond.

Diffusion welding (DFW) is a solid-state welding technique that produces a strong bond by facilitating diffusion and coalescence under controlled conditions using heat and pressure. Because it may prevent common metallurgical difficulties observed in conventional welding procedures, this specialized technology is vital in the field of metallurgy.

Friction stir welding (FSW) is a solid-state welding technique that forms the weld seam by manually stirring the metal to create friction heat and feeding a spinning tool along the joint line between two workpieces.

Welding is a material joining process where two or more parts are coalesced at their contacting surfaces through the application of heat and/or pressure.
