Welding processing has the following characteristics:
1, compared with bending, welding has the advantages of saving metal materials, high productivity, high joint strength, good sealing performance, easy to realize mechanization and automation.
2, compared with casting, welding process is simple, high production efficiency, save materials, low cost, is conducive to the renewal of products.
3, for large and complex structural parts, the use of casting welding, forging welding, punching welding composite process, can achieve small to big, complex to simple, to overcome the lack of casting or forging equipment capacity, is conducive to reduce costs, save materials, improve economic benefits.
4, can connect dissimilar metal, easy to manufacture bimetallic structure. For example, cemented carbide blade and turning tool rod are welded together to surfacing a layer of wear-resistant material on the surface of the worn workpiece to extend its service life.
