Welding is a fabrication process that involves joining materials, typically metals or 热塑性塑料, by applying heat, pressure, or both to create a strong, permanent bond. This technique is essential in product design and manufacturing, as it enables the assembly of complex structures and components with high structural integrity. Through various welding methods, such as arc, MIG, and TIG welding, engineers can innovate and enhance product performance while ensuring efficient production processes.
