Why does the following occur after welding?
Thread Content
Is there any welding expert who knows why this happens?
I think it is related to factors such as groove type, weld width, welding process, welding current, and welding time.
If it’s a multi-point diagonal segmentation, it might not be like this. Is there such a deviation at all the points on the circle? Uneven heating due to continuous welding?
The deviation is 0.28; the amount of misalignment isn’t that large. This situation may be caused by an unacceptable level of ellipticity in the non-standard thin-walled tube, as the welder failed to make it round, and this can be detected through a four-point inspection.

The measurements taken with a vernier caliper are not standardized. . . . Inaccurate. . It seems that there is a slight deviation in the outer diameters of these two, resulting in a slight misalignment. . It’s completely normal
How can you be sure that what you’re measuring is exactly the diameter? At the very least, take it several times and calculate an average.
