Steel Structure Production Quality Control

The 16th training：

Training Instructor: Yang Tongmin, Director of first Steel Structure Factory

Location: First Steel Structure Factory

Training time: July 6, 2016 (Wednesday) 17:00

Quality Control：

All projects of steel structure production must be processed and manufactured in strict accordance with the design requirements of drawings, and the relevant standards shall refer to the relevant specifications in 《Code for Acceptance of Construction Quality of Steel Structure Engineering  GB50205-2001》.

Production preparation: First,managers who are in charge of process carefully check the drawings. Then they will make preparations for each process, and start processing according to the drawing. If there is any problem, They will immediately contact the technical department.

In order to ensure product quality, the "three inspections" system for products should be implemented: self-inspection, mutual inspection, and special inspection. Each process should be conducted by strict self-inspection according to the quality control standards to ensure that unqualified parts and components are not transferred to the next process; mutual inspection should be carried out between different processes, and the parts that do not meet the quality requirements of this process cannot be accepted;

special inspection: First, it is required that the first products must be inspected by the head teacher, the template must be inspected, the entire production process must be inspected, and the problems arising in each process should be dealt with and rectified in time. Second, In the production process, quality inspectors should conduct random inspections and patrol the whole production line. In the product appearance treatment process, the quality inspector must carry out dimensional and appearance inspection on all products.

Technological process of steel structure production：

2. Blanking (paneling) 

3. First assembly  

4. Submerged arc automatic welding (straightening, drilling)  

5. second assembly  

6. CO2 gas shielded welding  

7. Shot blasting 

8. Slag cleaning, straightening, grinding  

9. Painting  

10. Product warehousing
