Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as as-cast porosity produced in the metal smelting process and optimize the microstructure.

Forging has a long history in China, and it has been continued by the production method of manual workshops. Probably around the beginning of the 20th century. It gradually appeared in the railway, military industry, shipbuilding and other industries with the production method of mechanical industrialization.

The existence of forging defects will affect the processing quality or processing quality of the subsequent process, and some will seriously affect the performance and use of the forgings, and even greatly reduce the service life of the finished products and endanger the safety.

There will inevitably be some defects in the production of forgings, some of which are unpredictable and some can be avoided, so it is necessary to avoid defects as much as possible in the forging process.

High specific strength, high specific stiffness, high specific elastic modulus, high fatigue strength, suitable for lightweight key components, and its comprehensive performance is much higher than other materials.

The microstructure and mechanical properties of forgings are related to many factors, and the forging ratio is one of the most important factors affecting the quality of forgings.

According to different transmission modes, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines.

The main difficulty in ultrasonic testing of large annular forgings is to consider both the detection sensitivity and the detection blind area.

Understand the parts drawings and data, understand the parts materials and pavilion-shaped structure, usage requirements, assembly relationships, and mold line templates

Forgings are first processed by the forging factory, and the forgings are inspected after forging. Forging is to select the corresponding forging equipment according to the material
