Product introduction
Submerged arc welding pipe: stable welding, high bearing pressure, preferred for heavy projects
Welding principle-deep penetration welding by submerged arc welding
Submerged arc welding (SAW) technology is mainly used for submerged arc welding pipes, that is, when welding, the arc burns under the flux layer, and the welding is completed by melting the base material and filler material. Because the whole process is covered with flux, the welding is more stable, the weld is dense and the strength is high.
Submerged arc welding can be divided into internal welding and external welding, which can meet the welding requirements of large-diameter and thick-walled steel pipes and is incomparable to traditional welding methods.
Technological advantages-bearing pressure, thick welding and adaptability to heavy load environment
High weld quality: deep welding and high joint strength, suitable for high-strength use;
Adapt to thick-walled pipes: large diameter and large wall thickness can also be easily handled;
High degree of automation: stable welding, reducing human error;
Strong pressure-bearing and anti-corrosion ability: it is mostly used in oil pipeline, offshore engineering, piling foundation and other projects with high requirements for strength and safety.
Submerged arc welding pipe is commonly used in bridge engineering, port and wharf pile foundation, long-distance oil and gas pipeline, wind power foundation pile and other major projects.
