How much do you know about SAW?
Submerged arc welding, also known as SAW, is a welding process used in many industries for its efficiency, ability to produce high-quality welds, and ease of use. This welding technique is particularly useful for welding thick materials together, such as pipes, plates, and other heavy structures.
What is the SAW?
SAW is an arc welding process that uses a blanket of granulated flux to protect the welding electrode from atmospheric contamination. The granulated flux is added to the joint, covering the electrode and the weld area, which helps to produce a strong, clean weld. When the welding electrode is brought close to the workpiece, an arc of electricity is created, melting the electrode and the workpiece. The filler material from the electrode is fed continuously into the weld puddle, creating a welded joint as it cools.
SAW Production Process
The process of SAW is relatively simple, which makes it easy to learn for beginners. One of the benefits of SAW is the ease of automating it, making it useful in mass production. The process can also be used to weld reactive metals and exotic alloys, which are otherwise difficult to weld using other methods.
The production process of SAW involves several steps, starting with the preparation of the workpiece. The two pieces of material that will be welded together are cleaned and degreased to remove any contaminants that could cause the weld to fail. After cleaning, the parts are placed in position, and the granulated flux is added to the work area. Next, the electrode is inserted into the flux. Once the electrode is in place, the power source is turned on, and the arc is created. The electrode is moved slowly along the joint, melting both the electrode and the metal workpiece. The flow of filler material is continuous, providing a strong weld.
