Main Process: Welding

Our precision welding system for steel structures includes power and communication towers, steel structure components, and carbon steel welded parts. We utilize COz gas shielded welding, TIG argon arc welding, submerged arc welding, spot welding, and projection welding. Types like butt, fillet, lap, circumferential, and groove welds are fully available.

Strictly controlled welding procedures include pre-welding treatments like degreasing, derusting, grinding, and weld cleaning for clean surfaces. CNC tooling positioning, symmetrical sectional welding, and low heat input technology prevent deformation and errors. Welds are smooth, uniform, and free of defects, ensuring strength and stability.

Post-welding, we polish, relieve stress, and finish. Anti-corrosion options—shot blasting, anti-rust oil, hot-dip galvanizing, powder coating—boost weather resistance and lifespan. Products undergo stringent tests like VT, dimensional re-inspection, MT, and PT. Meeting GB, ASTM, and JIS standards, they fulfill international export and engineering criteria.
