How to prevent problems with bolt balls
Bolt ball is a common component in the processing of space frames. Pay attention to the quality of the bolt ball during production and processing, so as to ensure the quality of engineering construction.
- Electric welding process; one of the processes that is prone to quality problems. The key to the quality problem of this process is the welding quality of electric welding, which causes the welding failure rate to reach over 80%, and the second is because of the actual operation of the road process. And the technical problems of the actual operation staff, resulting in welding quality problems.
- Spraying process; the quality problems of the process are specifically manifested in the large-scale fall of the paint film on the surface of the prefabricated component and part of it, which causes the paint film on the surface of the prefabricated component to fall, causing sagging, and the thickness of the paint film being insufficient. The unevenness of the thickness makes the color cast of the paint film large.
- Construction lofting and blanking process; this process belongs to the faucet before the production and processing of prefabricated components. Its quality also has an immediate hazard to the next process, and may even cause all the parts of the blanking to be damaged. The production is very extensive, so it is very necessary to improve the quality of the whole process before cutting the material.
- Installation process: This process occupies a very important influence on the quality of the production and processing of prefabricated components, and its quality is more harmful to the road process. Therefore, it is very important to improve the supervision of the whole process before installation.
