Tag welding is a technique used in the welding process to temporarily hold two pieces of metal together. This method involves applying small welds, known as tags, at specific points to secure the parts in place before performing the main weld. Tag welding helps ensure proper alignment and reduces the risk of distortion during the final welding process. This technique is commonly used in various industries, including construction and manufacturing, where precision is crucial. By using tag welding, welders can efficiently assemble complex structures, such as steel frames or automotive components, ensuring they meet design specifications and safety standards.
