Please, who can help me analyze the advantages and disadvantages of casting and welding in all aspects of production, as well as the complementarity in production
There are two kinds of concepts that cannot be compared together,
This requires the use of casting to produce precision parts, then welding, connecting them without space limitations.On the first floor, this statement seems very unprofessional. Castings can not be welded by welding. They are welded in castings and are usually used to repair defects
The casting is more precise, and the overall chemical composition is uniform. The process of casting with predetermined shape, size and performance is achieved, and the processing time is reduced and the cost is reduced. And it is widely used in welding, the workpiece made with casting compared to no means so sophisticated and the mechanical properties of the joint office has also changed. But it is more convenient and extensive than casting. Some special welding material is not up to the effect of casting can be made, and it is suitable for the manufacture of casting workpiece welding is not affected by this restriction greatly improved problem want to make the size of the workpiece, and the cost is not very high efficiency is very high.The complementarity between the two is also very strong, for example, a set of equipment needed to manufacture and is very large, which requires the use of casting first produced precision parts welding to connect them and not subject to the limitations of space.
