First, the welded steel Jiangmen
Advantages welded link: adaptation of the geometry is very strong, and the structure is simple, do not weaken the cross-section, fully automated operation, link sealing.
The disadvantage welding link: quality of material and high-Fen Chang of the welding requirements, in the heat-affected zone, the material can easily lead to local mutations, low residual stress caused by welding deformation and residual matter steel affordability.

Second, the riveted steel Jiangmen
Advantages rivet link: reliable conveying force, toughness and plastic properties are very good, easy to check quality, good dynamic performance carry
The disadvantage rivet link "structure is too complex, expensive labor and steel components

Third, the common bolt link Jiangmen Steel Structure
Common bolt link Advantages: Packing convenient and simple, simple device
Common link bolt bolt precision low shortcomings, but not easy to shear, high precision processing installation is complex, and the price is relatively high

Fourth, high strength bolts of steel link Jiangmen
Link high-strength bolts Advantages: friction-type shear tends to be small, good resiliency, very suitable for the load with the steel, strong athletic ability to withstand
High strength bolts link Disadvantages: friction surface treatment of hard, the installation process is too complex, high cost, to withstand shear link big or small, can not be used to withstand dynamic loads Steel
