- I need to detect the welding point on a large metal pipe, so I'm thinking of putting a marker on it to locate it. A color differentiating sensor would then be used to detect this mark.
- I see, but it seems that the marked position would be difficult to detect because of the influence of the uneven colors around the welded part, right?
- Yes, you're right. Do you have a better way of doing this?
- How about using laser displacement sensors on the inside and outside of the pipe and detecting any change in thickness to locate the welding point?
