I dissolve lines with the same attributes. However, if these lines join, they cannot be dissolved. How can it be done? enter image description here


You can use the dissolve algorithm with field selected to make dissolution only for those that have common algorithm.

And then use multipart to single part to have only connected lines. I think it should work well. If not share the result of step 1 and step 2.
