Welding Fixture table For Steel Structure
Welding Fixture Table For Steel Structure are specialized process equipment designed for positioning, supporting, clamping, and fixing large steel structure components (such as beams, columns, trusses, frames, etc.). Their core purpose is to ensure the precise relative positions, geometric shapes, and dimensional tolerances between multiple steel components during the welding process, thereby guaranteeing the quality, accuracy, and interchangeability of the final product.

• Ensuring precision and consistency: Welding Fixture Table is crucial for producing products that meet strict architectural/engineering standards (such as AISC, EN, GB).
• Improving production efficiency: It makes the assembly of large components fast and orderly, significantly shortening the production cycle.
• Controlling welding deformation: Effectively reducing correction work through rigid constraints and pre-deformation design.
• Reducing absolute reliance on workers' skills: Transforming complex spatial positioning problems into simple "leaning against positioning blocks" operations.
• Enhancing safety: Stably supporting workpieces to prevent overturning or movement during welding.
Products Workflow
Typical Workflow
1. Process and Fixture Design:
◦ Analyze product drawings to determine the assembly sequence, welding sequence, and key control tolerances.
◦ Design the overall structure of the fixture, positioning scheme, clamping points, and anti-deformation amount.
◦ Complete detailed engineering drawings and manufacturing.
2. Fixture Installation and Calibration:
◦ Install the fixture body at Welding Fixture Table in the workshop.
◦ Use high-precision instruments such as total stations and laser trackers to perform final calibration and adjustment of all positioning datums.
3. Workpiece Assembly:
◦ Use a crane to hoist main components (such as main beams, end plates) and lean them against the positioning datums.
◦ Install secondary components (stiffeners, connecting plates).
◦ Activate hydraulic or manual clamping mechanisms to firmly fix all parts, and pre-deformation may be applied.
4. Welding and Monitoring:
◦ Welders perform welding on the fixture according to the predetermined sequence.
◦ Changes in key dimensions may be monitored during the process.
5. Unclamping and Workpiece Removal:
◦ After welding is completed and cooled, release all clamping mechanisms.
◦ Due to the release of fixture constraints, the workpiece will have slight springback, but the deformation has been controlled within the allowable range.
◦ Hoist away the finished product for subsequent inspections (such as final dimension inspection, non-destructive testing).
6. Fixture Maintenance: Clean up welding slag and spatter, check for wear of positioning elements, and prepare for the next production cycle.
