Rectangular tube welding or connectors, which one is stronger?

Rectangular tube (RHS) is a type of pipe widely used in construction and industrial fields and is popular for its special shape and properties.

Advantages of rectangular tubes:

1. High strength: The rectangular tube is processed by a special process and has high tensile and compressive strength, and can withstand large pressure and tensile force.
2. Lightweight and flexible: Compared with traditional round pipes, rectangular pipes are lighter and easier to transport and install. At the same time, its unique shape also makes the rectangular tube more flexible when connecting and fixing.
3. High durability: The rectangular pipe has good corrosion resistance and weather resistance, and can be used for a long time in various complex environments, greatly extending its service life.
4. Beautiful and elegant: The surface of the rectangular pipe is smooth and difficult to accumulate dirt and dust, making its appearance always neat and beautiful.

5. Easy to process: Rectangular tubes can be cut, bent, drilled, etc. according to actual needs to easily meet various application requirements.

Features of rectangular tube welding:

Rectangular tube welding is formed by overlapping and welding two rectangular steel tubes at a certain angle. It has the following characteristics:
1. The welded rectangular tubes are tightly connected. For some structures that require frequent movement or continuous vibration, rectangular tube welding is a more reliable fixing method.
2. No other connectors are required during welding, which greatly reduces the cost of use and the impact on appearance, making the entire system more beautiful and elegant.
3. Since the welding points are directly fused together, the rectangular tube is stronger and more stable when carrying weight, is not easy to break, and has a longer service life.

Features of connectors:
The connector is to fix two rectangular steel pipes together with bolts or screws and other connectors. It has the following characteristics:
1. The connectors are more flexible and can be easily adjusted and replaced. There is no need to destroy the entire structure when the structure needs to be changed.
2. The connectors have high precision and are easy to control and adjust during installation, making the entire structure more precise.
3. The use cost of connectors is low, they can be mass-produced and used, and they do not require special technology.

Which one is stronger?
Generally speaking, rectangular tube welding is stronger than joints. The fusion of welding points makes the entire structure stronger and is suitable for structural situations that need to withstand high intensity and long-term repeated vibration. Connectors are more suitable for structures that require frequent changes or flexible disassembly, and their accuracy and usage costs are relatively low.

However, it should be noted that the quality of welding joints depends on the welding process and the level of welding technology. If welded improperly, defects such as cracks and pores may easily occur, causing the entire structure to be unstable. At the same time, the location of the welding points also needs to take into account the stress state, and the location and number of the welding points must be reasonably determined.

In summary, the selection of fixing methods for rectangular tubes needs to be comprehensively considered based on different use occasions and needs to achieve better results.
