Forging testing equipment quality appraisal

HTMLTAGTOKENO exercise detection equipment is based on multimodular no-loss detection and digitization analysis, which combines ultrasound detection, X-ray imaging and three-dimensional scanning techniques to achieve co-ordination control of internal defect identification and size accuracy of the exercise, and is widely used in areas such as aerospace, energy equipment and heavy machinery. In aviation manufacturing, it is used for internal complication of engine plates; in the field of nuclear power, for the assessment of the balance of the wall thickness of the pressure vessel; and in the orbital traffic industry, for the protection of the fissure warning of the axle exercise. Compared to traditional methods of detection, the exercise detection equipment has a high detection rate of defects, a three-to-five-fold increase in the speed of detection and a high retroactivity of data, and is the core of quality control in modern smart manufacturing. The TMLTAGTOKEN1 HTMLTMTAGTOKEN2 medium-level testing is a product quality assessment service with a court-registered register, which provides quality assurance services for exercise detection equipment, has a professional identification team and advanced equipment, and provides fair and accurate validation of the quality of exercise detection equipment.

With the improvement of quality requirements for high-end forgings, there has been a significant increase in testing equipment disputes. The judicial dispute focuses on:

1. Disputes over performance indicators: whether the detection sensitivity reaches the standard and whether the three-dimensional scanning accuracy meets the contract requirements;

2. Material defects: the performance attenuation of the sensor piezoelectric chip and the purity of the tungsten target of the X-ray tube are not enough

3. Process problems: Defects in the detection path planning algorithm lead to missed detections, and the robotic arm positioning repetition accuracy is >0.05mm exceeding the standard;

4. Contract performance dispute: The software module or hardware configuration of the delivered equipment does not match the technical agreement.

0 Such cases need to pass standard test block verification, system stability testing and core component disassembly analysis to clarify the quality responsibility.

For forging quality appraisal, the following technical methods are usually used:

1. Ultrasonic flaw detection: Use ultrasonic waves to penetrate the inside of forgings to detect whether there are cracks, inclusions and other defects.

2. Magnetic particle inspection: Apply magnetic powder to the surface of forgings, generate magnetic lines of force through magnetization, and expose crack defects on the surface of forgings.

3. Eddy current flaw detection: Use the electromagnetic field changes generated by eddy currents on the surface of forgings to detect defects such as cracks and pores on the surface of forgings.

The applicant, a nuclear power equipment company, signed a "Fully Automatic Ultrasonic Inspection System Procurement Contract" with a testing equipment manufacturer, the respondent, stipulating that the equipment can detect defects equivalent to Φ0.5mm. During the reactor pressure vessel inspection, the system missed detecting Φ1.2mm inclusions in the flange area, resulting in rework losses. The manufacturer argued that it was caused by incorrect parameter settings by the operator.

Identification analysis results:

The quality analysis expert group discussed and comprehensively analyzed the relevant information of "Forging Inspection Equipment", contract technical agreements, on-site inspection case materials and other data, and made the following quality analysis opinions: HTMLTA In the test of the standard CSK-IA test block of the equipment involved in GTOKEN5

, the reflection amplitude of the Φ0.5mm cross hole only reached 40% of the reference height (contract requirement ≥80%); the probe damping resistance deviation was >15% (standard ≤5%), resulting in the pulse width exceeding the standard; the repetitive positioning accuracy of the motion mechanism was 0.08mm (agreement ≤0.03mm).

The appraisal conclusion concluded that the core performance of the equipment did not meet the technical agreement, and hardware defects and software sensitivity threshold setting errors jointly led to missed detections.
