Almost all forging inspection work is completed in the forging workshop, including: inspection of in-process and final dimensions of forgings, visual inspection of surface quality, hardness inspection, ultrasonic inspection and material grade resolution inspection.

Quality supervision during the production process includes:

1. Inspection of heating furnace temperature and uniformity

2. Calibration of temperature control instruments and thermocouples

3. Decomposition of fuel composition

4. Analysis of protective atmosphere composition in the furnace

5. Analysis of lubricating oil composition

6. Analysis of oil composition

7. Analysis of coating composition and performance

8. Coating and coating thickness inspection

9. Check the particle size of clean abrasives and sand

These forging inspection methods are generally also attached to the forging plant's workshop.

The inspection instruments and equipment used in the central laboratory and workshop of the forging plant should be calibrated and maintained regularly by the forging plant or its superior metrology agency.
