Laser welding process and principle
Welding Processes and Principles 1.1 Definition of Welding Welding is the process of joining two or more materials, either similar or different, by creating atomic or molecular bonds through heating, applying pressure, or a combination of both. The methods used to facilitate these bonds include heating, pressing, or both simultaneously. 1.2 Classification of Metal Welding Metal welding can be categorized based on the characteristics of the process into three main types: fusion welding, pressure welding, and brazing. Fusion Welding In fusion welding, the workpieces to be joined are heated until they melt and form a molten pool. Once the molten pool cools and solidifies, the materials are joined. This process […]
