The existence of titanium forging defects, some will affect the subsequent process treatment quality or processing quality, and some will seriously affect the performance and use of forgings, and even greatly reduce the service life of the finished product, endangering safety. Therefore, in order to ensure or improve the quality of forgings, in addition to strengthening quality control in the process and taking corresponding measures to eliminate the occurrence of forging defects, necessary quality inspection should also be carried out to prevent the flow of forgings with defects that have adverse effects on subsequent processes (such as heat treatment, surface treatment, cold working) and performance. After quality inspection, remedial measures can also be taken according to the nature of the defect and the degree of influence on the use of the forged forging, so that it meets the technical standards or the requirements of use.
Therefore, forging quality inspection in a sense, on the one hand is the quality control of the forged forging, on the other hand is to point out the improvement direction of the forging process, so as to ensure that the quality of the forging meets the requirements of the forging technical standards, and meet the requirements of design, processing and use. The inspection of forging quality includes the inspection of appearance quality and internal quality. The appearance quality inspection mainly refers to the inspection of the geometric size, shape, surface condition and other items of forging; The inspection of internal quality mainly refers to the inspection of chemical composition, macroscopic structure, microstructure and mechanical properties of forgings.
