Regarding radiographic inspection of fillet welds
Thread Content
I would like to ask everyone: can fillet welds be inspected using radiographic testing? If not, why?
It’s not possible to apply patches to fillet welds, and the angle also affects imaging; generally, magnetic particle or penetrant testing is used
Radiographic testing can only be carried out with equipment designed for inspecting fillet welds, but the cost is relatively high.
What was said on the 2nd floor is correct – if the position of the fillet welds isn’t suitable, how can soldering be carried out?
We didn’t buy it either; the equipment is very expensive, and we weren’t aware of the details so we didn’t do any research. Sorry!
According to the information provided, fillet welds can be inspected using ultrasonic testing, but the process is complicated.
You can RT. . There will be some difficulties. The standards are set by the enterprises. It’s not in JB/T4730. It is included in NB/T47013, but it is not very suitable for implementation. Due to issues with thickness differences, the problem of the negative not sticking tightly, and the issue of the incident angle. It can cause issues such as enlarged weld images, enlarged defect images, as well as defect displacement and deformation. The issue of penetration thickness versus evaluation thickness. If one wishes to assess the quality of internal controls, an enterprise standard can be established by referring to DL/T 541-2014 \"Radiographic Inspection and Quality Grading of Welds in T-Joints and Corner Joints in Steel Fusion Welding\".
It’s possible, but it’s generally not used.
