The welding structure has a series of advantages that other structures, primarily reflected in the following aspects.

1.The overall rigidity of the welding steel structure is very strong. Because welding is a connection method of weldment atoms, it has high stiffness, good Integral rigidity, so under the outside force, it will not have larger deformation because of gap move like other mechanical machines. The strength and rigidity of welding seam is equal or close to the base material, therefore it is able to bear various loading.

2. Welding steel structure has high strength and light weight. It is made of hot rolled steel, so it is able to bear high impact loading, and the strength of welding steel structure is much higher than structures made from bricks, stones, concrete etc. building materials. Furthermore, the strength of welding seam by using modern welding technology is higher than the base material. 

The welding parts or welding components can be welded together directly without any other additional connection parts. Comparing with riveting structure, the weight can be reduced by 10%-20% for same structure.

3. Welding steel structure has high safety. Because welding steel structure has some plastic deformation, normally it will not suddenly break due to accidental overloading or partial overloading, rather, a big deformation sign occur in advance, so that remedial measures can be taken before accident. And steel material has very good toughness, so the structure made by steel has a strong adaptability to the dynamic load on the structure, its characteristic makes welding steel structure high safety.

In a certain range of stress, steel is in the ideal elastic state, which matches the basic assumption of engineering mechanics, so the result of calculation is correct, to ensure the safe use of the welding structure.

4. Good compactness of welded structures. Due to good compactness of welding seam, so welding structure can ensure the air tightness and water tightness requirements, This is an essential and important condition for pressure vessels, such as boilers, gas storage tanks, oil storage tanks, and so on.

5. Steel structure is economic. The steel structure is made by steel profiles is even more economic than directly rolling a profile. For example, a big size “I” beam made by steel profiles welding is cheaper than directly rolling a profile.

Welding steel structure production does not need heavy, special and very expensive machines, it is less investment, rapid, and it is suitable for deferent kind of steel structure, product replacement fast, good economic returns.
