Welding -The Manufacturing of Steel lattice tower
The tower base is the critical connection between the steel tower and its foundation, bearing the enormous loads transmitted by the entire tower. Typically fabricated by welding together base plates, shoe plates, and stiffeners, it features a compact structure with dense welds and demands exceptional welding quality.
Product Info
All our welders hold special operation certifications issued by authoritative bodies and are proficient in structural steel welding codes, such as GB 50661 and AWS D1.1. Prior to production, our technical team prepares Welding Procedure Specifications (WPS) for complex assemblies like tower bases, defining base metal properties, filler metal matching, preheat temperatures, welding parameters, and inter pass temperature control. During fabrication, semi-automatic gas metal arc welding (GMAW/MAG) is preferably used, with work pieces manipulated on dedicated welding positioners to maintain the weld in the optimal flat position, ensuring proper penetration and formation. For critical load-bearing welds, 100% non-destructive testing is implemented: ultrasonic testing (UT) inspects internal defects, while magnetic particle testing (MT) detects surface and near-surface cracks. All inspection records are archived in the quality traceability system. After welding, components undergo stress relief and dimensional correction before flowing to the hot-dip galvanizing process. With rigorous welding quality standards, Qingdao Best Tower ensures the tower bases and welded nodes of every tower perform safely and reliably under extreme load conditions.
