China Welding Fabrication Service-Advantages of Welding Fabrication

The welded structure has a series of advantages unmatched by other structures, mainly reflected in the following aspects:

1. The integrity of the welded structure is strong. Since welding is a connection between metal atoms, it has high rigidity and good integrity. Under the action of external force, it will not cause excessive deformation due to gap changes like other mechanical connections. Therefore, the strength and stiffness of welded joints can generally reach the same The base metal is equal or similar, and can withstand various loads with the base metal.

2. The welded structure has high strength and light weight. Welded structures are mostly made of rolled materials, which have strong impact load capacity, and the strength of steel is many times higher than that of building materials such as masonry and concrete. The strength of welded joints manufactured by modern welding technology is higher than that of base metal.

Parts or components of welded structures can be connected directly by welding without any additional connectors. Compared with the riveted structure, the mass with the same structure can be reduced by 10% to 20%.

3. The safety performance of the welded structure is high. Due to the good plasticity of steel, under normal circumstances, it will not cause sudden rupture and damage due to accidental overloading or local overloading, but a large deformation omen will appear in advance, so that remedial measures can be taken. Steel also has good toughness, strong adaptability to dynamic loads acting on the structure, and provides a reliable guarantee for the safe use of welded structures.

Within a certain stress range, the steel is in an ideal elastic state, which is in line with the basic assumptions used in engineering mechanics, so the calculation results are accurate and reliable to ensure the safe use of welded structures.

4. The compactness of the welded structure is good. Due to the tightness of the welded seam, the welded structure can ensure the air tightness and water tightness of the product, which is an indispensable and important condition for the normal operation of pressure vessels such as boilers, gas storage tanks, and oil storage tanks.

5. The economic benefits of the welded structure are good. Welded construction is more economical than rolling when using some profiles. For example, large I-beams (height greater than 700mm) welded with wide flat steel and steel plates are often cheaper than rolled sections.

Welded structure production generally does not require large, special and expensive equipment, low investment, quick results, easy to adapt to the production of different batches of products, fast and convenient product replacement, and good economic benefits.
