How to Test Welds?

The most common non-destructive tests to check welds are visual inspection, liquid penetrant, magnetic particle, eddy current, ultrasonic, acoustic emission and radiography.

How to Test Welds?

Testing welds is an important part of ensuring the strength and reliability of any welded joint. Welds are used to join two or more pieces of metal, and are often used in metal fabrication and construction projects. It is important to test welds to ensure that they are properly fused and will withstand the stresses of the application. There are several methods for testing welds, depending on the type of weld and the requirements of the job.

Visual inspection is the simplest and most common way to test welds. The visual inspection should include checking for any gaps, cracks, or other flaws in the weld. A good visual inspection will also include checking for any signs of contamination, such as dirt, grease, or rust. If any of these are present, the weld should be redone or rejected.

X-ray inspection is another common method for testing welds. This type of inspection uses X-rays to detect any flaws in the weld. X-ray inspection is especially useful for locating cracks or other flaws that may not be visible to the naked eye. X-ray inspection is sometimes used in combination with other methods, such as penetrant testing or dye penetrant testing.

Penetrant testing is a popular method for testing welds
