Welding Process
1. The reinforcing cage should be welded using core wire welding, either jet gas shielded welding or argon arc welding.
2. The weld should be uniform, and the weld point should be perpendicular to the surface of the reinforcing cage or at a sharp angle. Welding defects such as slag inclusions, slag-free welds, and cracks are prohibited.
3. The length of each weld point should be no less than 2/3 of the diameter of the reinforcing cage, and the weld point should be in an arc state.
4. When performing continuous automatic welding of the reinforcing cage, the reinforcing cage must be cut to the same length to ensure that the length of each weld is equal.
Equipment Requirements
1. Before welding the reinforcing cage, the equipment must be thoroughly inspected to ensure normal operation.
2. Welding and drying equipment must comply with national standards, and the installation and maintenance of the equipment must meet the requirements of the equipment manufacturer.
3. Reliable welding equipment must be used, and the equipment must be kept clean and in good maintenance condition.
Inspection Standards
1. The weld length of the reinforcing cage should meet the design requirements and specifications.
2. The weld joint should be flat, free from unevenness, slag inclusions, porosity, and other defects.
3. The weld joint should have sufficient load-bearing capacity and should not be under severe load.
In summary, reinforcing cage welding is a steel reinforcement processing technique used to enhance the reinforcement of building structures. Strict adherence to specifications and safety regulations is essential to ensure the quality and safety of the reinforcing cage welding.
