Steel Coil Plate: Serving as the primary raw material for spiral submerged arc welded pipes, steel coil plate undergoes rigorous physical and chemical testing to ensure its quality meets production requirements. Prior to forming, the steel coil plate undergoes leveling, edge trimming, edge planing, surface cleaning, conveying, and pre-bending processes to guarantee its shape and surface quality.
Welding Wire: Welding wire is the metal wire used to fill the weld joint during the welding process. The selection of welding wire is crucial to welding quality, requiring high strength, high toughness, and other characteristics to ensure stability and reliability during the welding process.
Flux: Flux plays a role in protecting the weld metal and removing impurities generated during the welding process, thereby enhancing the quality of the weld joint.
