2023-12-06Bolted ball space frame and welded ball space frame are two common types of ball mesh structural connections, and they have some differences in connection methods and structural performance. The following are their main differences:
 Bolted ball space frame |
 Welded ball space frame structure |
|
|
Connection method |
Bolted connection is a way to connect the parts of ball space frame together through bolts, nuts and other connecting elements. This connection is relatively flexible, can be assembled and disassembled on site, easy to transport and installation. |
Welding is the process of fixing the parts of a ball grid together by welding. Welded connections are generally stronger, but also mean that modification and dismantling of the structure is relatively more difficult. |
|
Construction and fabrication efficiency |
Construction and fabrication is relatively quick as bolted connections usually do not require special welding processes and can be more easily assembled on site. |
Welding needs to be done during the fabrication process and usually requires more equipment and specialised processes, which can lead to longer fabrication and construction lead times. |
|
Flexibility |
More flexible and easy to adjust and modify as the connecting sections can be replaced or adjusted with relative ease. |
Relatively more difficult to modify and adjust structurally and require experienced welders to operate. |
|
Cost |
Typically relatively economical during the fabrication and installation phase, but the cost of bolting and connecting sections can add up. |
The process of fabrication and welding may require more resources and labour and therefore may be more costly in some cases. |
When choosing between bolted and welded ball space frame, factors such as the specific requirements of the project, budget, life cycle and the need for frequent dismantling need to be taken into account.
