Oil cylinder is a large container for storing liquid or gas.

Welding and connection are very important steps in the manufacturing process of oil cylinder.

They not only affect the quality and service life of the oil cylinder, but also relate to the safety and reliability of the oil cylinder.

1、 Oil cylinder manufacturer The appropriate welding methods and materials will be selected.

Common welding methods include manual arc welding, gas shielded welding and welding robots.

Manual arc welding is a commonly used welding method. It uses the arc to heat the workpiece to the molten state, and uses the welding electrode or welding wire to fill the weld.

For gas shielded welding, inert gases such as argon or carbon dioxide are used to protect the weld, which can obtain better welding quality.

The welding robot automatically completes the welding operation through program control, which improves the production efficiency and welding precision.

2. Before welding, the oil cylinder manufacturer will prepare the workpiece.

This includes cleaning the surface, removing oxides and oil to ensure that the welding area is clean.

For larger cylinders, it may be necessary to cut the steel plate to the required size by flame cutting or mechanical cutting.

Then, bend, punch and open the cut steel plate, and then assemble the parts.

3. During welding, the oil cylinder manufacturer will operate according to the design requirements and process procedures.

The welding personnel need to adjust the welding current, voltage, welding speed and other parameters according to the welding process requirements to ensure the quality of the weld.

For larger oil cylinders, it may be necessary to weld with multiple people to improve production efficiency.

In the welding process, the welding personnel need to pay attention to protect their own safety, such as wearing protective glasses, masks and gloves.

4. Connection refers to the assembly of various parts of the cylinder.

Oil cylinder manufacturers usually adopt threaded connection, butt welding connection and flange connection.

Threaded connection is a common connection method, which is connected with each other by fixing the threaded ferrule or threaded joint on the parts.

Butt welding connection is to align two parts to be welded, melt them by heating, and rapidly pressurize them together to cool and solidify.

Flange connection is to butt joint the flange faces of parts and fix them together with bolts to achieve the purpose of connection.

5. In the connection process, the oil cylinder manufacturer needs to ensure the tightness and reliability of the connection.

When connecting, it is necessary to carefully select appropriate thread specifications and materials to avoid problems such as thread looseness and oil leakage.

Butt welding connection and flange connection shall pay attention to welding quality and connection sealing.

The quality of welding will directly affect the strength and reliability of the connection.

The sealing of the connection is related to the service life and working effect of the oil cylinder.

In a word, welding and connection are indispensable links in cylinder manufacturing. The oil cylinder manufacturer will select appropriate welding methods and materials, and carry out welding and connection operations in strict accordance with the design requirements and process specifications. Through scientific welding and connection technology, the quality and reliability of the oil cylinder can be guaranteed, and its service life and working effect can be improved.
