What online nondestructive testing solutions are available in modern industrial manufacturing?

2021-04-10

Nondestructive testing and online inspection are both essential inspection methodologies for modern, automated industrial production. By customizing precision instruments and providing more convenient inspection methods, these approaches not only achieve high-efficiency measurement but also deliver greater economic benefits. Nondestructive testing refers to the use of physical or chemical methods—leveraging modern technologies and equipment—to detect internal and surface structural features, conditions, and defects in test specimens, including their types, quantities, shapes, and properties. This is accomplished by exploiting changes in thermal, acoustic, optical, electrical, and magnetic responses that arise from abnormalities or defects within the material’s internal structure, all while ensuring that the tested object’s service performance and internal integrity remain undamaged and unaffected.

32 Questions to Help You Understand Nondestructive Testing—Ultrasonic Testing

32 Questions to Help You Understand Nondestructive Testing—Ultrasonic Testing 01 What is Nondestructive Flaw Detection/Nondestructive Testing? (1) Nondestructive flaw detection is a testing method that examines the surface and internal quality of inspected components without damaging the workpiece or the raw material in its service condition. (2) Nondestructive testing: Nondestructive Testing (abbreviated as NDT). 02 What are the commonly used flaw detection methods? There are many nondestructive testing methods; according to a survey and analysis by NASA, they can be categorized into six major types comprising more than 70 specific techniques. However, in practical applications, the following methods are relatively common: Conventional nondestructive testing methods include: – Ultrasonic

An Analysis of the Similarities and Differences Between the Two Major Qualification Certification Standards for Nondestructive Testing: ISO 9712 and TSG Z8001

2021-03-16

At present, there are numerous domestic certification systems for nondestructive testing personnel, which can pose challenges for enterprises and institutions when conducting qualification assessments and arranging for the certification of their NDT personnel. In China, the majority of certifications are based on two major standards—ISO 9712:2012 and TSG Z8001-2019. What are the key similarities and differences between the certification systems corresponding to these two standards?

What is the quality inspection agency for steel structure projects?

2020-02-18

Structural steel quality inspection agencies—structural steel, as the name suggests, is a type of structure manufactured and processed primarily from steel, and it is now an extremely important category in the construction industry. Thanks to the inherent characteristics of steel—lightweight, high strength, and excellent resistance to deformation—steel structures have earned widespread recognition within the building sector and are being increasingly applied across a broad range of construction projects. The penetration rate of steel structures in a country has come to serve as an indicator of its level of economic development: the greater the number of steel infrastructure facilities, the higher the country’s economic and technological standing. In China, following the 2008 Olympic Games’ main stadium…

What inspections are required for steel structure projects?

2020-02-18

What exactly does structural steelwork inspection entail? Many people are unclear about this, so let me explain. The inspections include: measurement of member dimensions and flatness; detection of surface defects on members; examination of connections (welded joints and bolted connections); assessment of steel corrosion; and measurement of fire-resistant coating thickness. If the steel does not come with a factory certificate of conformity, or if there are doubts about its quality, mechanical property tests should be added, and chemical composition analysis should be conducted when necessary. II. Scope of Application for Various Structural Steel Inspection Codes III. Measurement of Member Dimensions and Flatness For each dimension, measurements shall be taken at three locations along the member, and the average of these three readings shall be taken as the representative value for that dimension. The dimensions of steel members…
