Structural Steel Welding Construction

Precise Adaptation

Using submerged arc welding and gas shielded welding, structural steel welding construction adapts to steels such as Q355B, customizing components such as steel columns and beams, adopting factory prefabrication + on-site splicing and complying with GB 50661-2011 standards, adapting to high-rise buildings and factories.

Multi-layer and multi-pass welding is adopted with each layer 3-5mm thick, and 100% of welds pass level Ⅱ ultrasonic flaw detection. Shot blasting derusting + fluorocarbon paint coating ≥120μm ensures 15-year weather resistance. Flaw detection and anti-corrosion inspection reports are provided.

Large welding positioners improve efficiency, with prefabricated part accuracy of ±1mm. Prefabricated parts are delivered in phases according to construction schedules, with on-site splicing guidance provided by technical personnel to coordinate with hoisting plans and ensure smooth installation.

Structural steel welding construction realizes precise adaptation through high-strength processes and prefabrication modes. Multi-layer welding and flaw detection ensure quality, and precision control and hoisting coordination improve delivery efficiency, providing safe and stable structural welding solutions for high-rise buildings and other projects.
