Titanium forging defects exist, and some will influence the follow-up process quality or processing quality, while others seriously affect the performance and use of titanium forgings, and even greatly reduce the life of finished products, endanger the safety. Therefore, in order to ensure or improve the quality of titanium forging, in addition to the process to strengthen the quality control, take appropriate measures to prevent the emergence of titanium forging defects, but also the necessary quality inspection to prevent the subsequent processes (such as heat treatment, surface treatment, Cold work) and the use of the performance of the adverse effects of titanium defects for the follow-up process. After the quality inspection, but also according to the nature of the defect and the extent of use of the titanium forging to take remedial measures to meet the technical standards or the use of the requirements.

Therefore, the quality inspection of titanium forging in a sense, on the one hand is the quality of titanium forgings checked, on the other hand is to improve the direction of the forging process to ensure that the quality of titanium forging forgives meet the technical requirements of titanium forging, And meet the design, processing, use on the requirements.

Titanium forging quality inspection, including the appearance of quality and internal quality of the test. Appearance quality inspection mainly refers to the test of the geometric size, shape and surface condition of the titanium forging. The inspection of the internal quality mainly relates to the inspection of the chemical composition of the titanium forging, the microstructure, the microstructure and the mechanical properties of the titanium forging.

Specifically, the appearance quality test of the titanium forging is to check the shape of the titanium forging, whether the geometric dimensions conform to the requirements of the drawings, whether the surface of the titanium forging is defective, what is the defect of their nature, and what are their morphological features? The surface of the test content is generally to check whether the surface of titanium forging surface cracks, folding, wrinkles, pressure pit, orange peel, blistering, scarring, corrosion pits, bumps, foreign objects, not full, pits, Scratches and other defects. The internal quality of the inspection is to check the inherent quality of the titanium forging itself is the appearance of quality inspection can not find the quality of the situation, it includes both the internal defects of titanium forgings, but also to check the mechanical properties of titanium forgings, and important parts, key pieces Or large-scale titanium forgings should also be chemical composition analysis. For internal defects we will check the titanium forgings by means of low magnification check, fracture check, high power inspection method, such as internal cracks, shrinkage, loose, coarse crystal, white point, dendritic crystal, flow line does not meet the shape, Disorder, through flow, coarse crystal ring, oxide film, stratification, overheating, burned tissue and other defects. the mechanical properties is mainly to check the room temperature tensile strength, plasticity, toughness, hardness, fatigue strength, high temperature instantaneous fracture strength, high temperature lasting strength, sustained plasticity and high temperature creep strength.

As the titanium forging parts, in the course of the use of its force, the degree of importance, different working conditions, the materials used and metallurgical processes are different, so different parts of the above situation and in accordance with the requirements of the sector will be part of the titanium forging Out of the category, different departments, different standards for titanium forging classification is also different. But in any case, for the overall quality of titanium forging inspection are inseparable from the two categories of inspection, that is, the appearance of quality and internal quality of the test, but the different types of titanium forgings, the specific test items, inspection and inspection requirements Different fills.
