Medical titanium wire The manufacturer introduces the existence of defects in titanium forgings, some of which will affect the quality of subsequent processing or processing, some of which will seriously affect the performance and use of forgings, and even reduce the service life of finished products. 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 forgings with defects that have adverse effects on subsequent processes (such as heat treatment, surface treatment, cold processing) and service performance from flowing into subsequent processes. After the quality inspection, remedial measures can also be taken for the forged pieces according to the nature of the defect and the degree of impact on the use, so as to make them meet the technical standards or use requirements.

Therefore, the quality inspection of forgings, in a sense, on the one hand, is to check the quality of the fabricated forgings, on the other hand, it is to point out the direction of improvement for the forging process, so as to ensure that the quality of forgings 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. Appearance quality inspection mainly refers to the inspection of geometric dimension, shape, surface condition and other items of forgings; The inspection of internal quality mainly refers to the inspection of chemical composition, macrostructure, microstructure and mechanical properties of forgings.

Specifically, the appearance quality inspection of forgings is to check whether the shape and geometric dimensions of forgings meet the requirements of the drawing, whether there are defects on the surface of forgings, what kind of defects are they, and what their morphological characteristics are. The inspection content of surface condition is generally to check whether there are surface cracks, folds, wrinkles, indentation, orange peel, blisters, scars, corrosion pits, bruises, foreign objects, underfilled, pits, lack of flesh, scratches and other defects on the surface of forgings.
