Sheet metal connecting, held by welding, riveting, and adhesive, thread connection. We adopt the mode of connection: welding and riveting, thread connection.
1. The welding butt welding is a partial or whole heated or make the weldment produces plastic deformation, or heat and plastic deformation at the same time, can realize the process method of permanent. Can be divided into: manual electric arc welding, gas shielded arc welding, laser welding and gas welding, welding and resistance welding. We held by gas shielded welding and resistance welding.
1.1 gas shielded arc welding in gas shielded arc welding, the electrode arc zone and weld molten pool are in under the aegis of protective gas. Using argon gas protection weld surface oxide and no inclusions. Can be in any space position welding, weld can be observed with the naked eye in the forming process and adjust High production efficiency. The second oxygen gas shielded welding is cost is low.
1.2 contact welding
Contact welding is instantaneous heating connection parts in molten state or not under the molten state of the welding pressure forming welding method of welding joint. It can be divided into the butt welding, spot welding and seam welding.
2. Thread connection
Threaded connection is installed
Easy, easy disassembly, the advantages of simple operation, often for steel structure of the detachable connection. It can be divided into screw connection and bolt connection.
3. The riveting
Is the metal structure with rivet riveting connected parts or assembly method, rivet sort is more, we commonly used rivet has closed form round head core pulling rivets, closed form countersunk head core pulling rivets and open mouth round head core pulling rivets, open rack countersunk head core pulling rivets.
The length of the rivet according to the following formula:
L=0.8d+1.1t
D: the rivet diameter
T: thickness
4. The adhesive
With dope the required fittings bonding together a connection method.
