Welding generally refers to the joining of metals. It is a forming method that uses heat or pressure, or both, to create interatomic bonds between two separate objects, thus joining them into a single piece.
Features of Welding Production:
1. It conserves metal materials and achieves lightweight structures.
2. It can be used to combine small components into larger ones, or to reduce large components to smaller ones, enabling the manufacture of heavy and complex machine parts. This simplifies casting, forging, and cutting processes, achieving optimal technical and economic results.
3. Welded joints exhibit excellent mechanical properties and sealing.
4. It can be used to create bimetallic structures, fully utilizing the material’s properties.
Applications: Welding technology is widely used in machinery manufacturing, shipbuilding, construction, power equipment production, aviation, and aerospace.
Disadvantages: Welding technology also has some drawbacks, such as the inability to disassemble welded structures, which makes maintenance inconvenient; the potential for welding stress and deformation within welded structures; and the often uneven microstructure and properties of welded joints, which can lead to welding defects.
