Joining processes refer to methods used to connect two or more materials together, often in manufacturing and construction. Common techniques include welding, soldering, and adhesive bonding. Each method has its own advantages and is chosen based on the materials involved and the desired strength of the joint. These processes are essential in various industries, including automotive, aerospace, and electronics. For example, welding is frequently used in automotive assembly to create strong, permanent joints, while soldering is commonly employed in electronics to connect components on circuit boards.
