24. What raw materials are needed for spiral welded pipes?

Strip coil: As the main raw material for spiral seam submerged arc welded pipes, strip steel coils need to undergo strict physical and chemical inspections to ensure that their quality meets production requirements. Before forming, the strip is leveled, trimmed, planed, surface cleaned and conveyed, and bent to ensure its shape and surface quality.
Welding wire: Welding wire is a metal wire used to fill the weld seam during the welding process. The selection of welding wire is crucial for welding quality, requiring high strength and toughness 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 improving the quality of the weld.
