Resistance welding (RW) encompasses a range of fusion-welding techniques that achieve coalescence through a mix of heat and pressure.

Electron beam welding (EBW) is a technique that achieves coalescence using a focused stream of high-velocity electrons directed at the weld joint.

Oxyfuel Gas Welding (OFW) is a welding method that uses oxygen and a mixture of different fuels to produce a flame. The main distinction between

Arc welding is the name given to a class of welding processes that melt and fuse metal together using an electric arc as the heat source. To create a joint between the metals, this method may or may not need pressure or filler metal. 

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.
