Steel Strip Coil: As the primary raw material for spiral seam submerged arc welded pipe, steel strip coil undergoes rigorous physical and chemical testing to ensure its quality meets production requirements. Before shaping, the steel strip undergoes flattening, edge trimming, edge planing, surface cleaning, conveying, and pre-bending processes to ensure its shape and surface quality.
Welding Wire: Welding wire is the metal wire used to fill the weld seam 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 seam.
