According to the general visual inspection rules, a mirrored borescope or a fiber optic viewing system can be used where access for direct visual inspection is restricted. This is usually by agreement between the contracting parties. So, What is a Borescope? A borescope (occasionally called a boroscope, though this spelling is unusual) is an optical…

What is a Dye Penetrant Testing?
Dye penetrant Testing or also known as penetrant testing (PT), is a commonly applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials such as metals, plastics, or ceramics. Penetrant can be applied to all non-ferrous materials and ferrous materials, although magnetic-particle inspection (MPI) is often used instead for ferrous components…
What is a Magnetic Particle Testing?
Magnetic Particle Testing (MPT) is a non-destructive testing (NDT) process for detecting surface and low subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process sets a magnetic field into the part to be magnetized by direct or indirect magnetization. What is the Basic Principle of Magnetic Particle…
What is Ultrasonic Testing?
Ultrasonic Testing (famously known as U.T.) is one of the most important methods in non-destructive testing. It is mainly used to detect defects in parts and materials and determine material’s thickness. The ultrasonic testing equipment is quite portable therefore making it suitable for inspecting large, irregularly shaped, or heavy stationary parts. AliExpress.com Product – Free…
Visual Intelligence For Welding Inspectors
How many time have you been trying to figure out why the defect occur? What is there to explain in your Root Cause Analysis report when you don’t have any idea why the defect exists in the first place? Maybe you haven’t been looking close enough or from a different perspective. Maybe welding inspectors need to learn visual intelligence…
What is Radiographic Testing?
Radiographic testing (or famously known as R.T.) is a process where penetrating radiation beam passes through a test object. The transmitted radiation is then collected by a form of sensor that is capable of measuring the relative intensities of the penetrating radiations imposing upon it. This sensor is called the radiographic film. Nowadays, radiographic testing…
How to Use the Bridge Cam Gauge
The Bridge cam gauge is an exclusive and multipurpose welding gauge used especially on welded surface and joints. It is a very handy visual inspection tool for welding inspectors. The gauge has a rotating dial and a sliding pointer to measure weld features. The measurement is displayed in inches and millimeter up to 2” or 60mm. You…
