Like the title.
I wondering what's the difference between glued connection and solvent welded connection.
If anyone knows, please give a detailed description, and how about hub and socket connections with the above two connections?

Solvent weld is a technical way of saying glued connection.

I disagree. Solvent welded uses the existing material. It softens it and then the solvent evaporates.

Glued uses a different material. . g superglue or epoxy to bond the materials. There is now the possibility of expansion differences.

You can also have "plastic welded" joints. We had a chemical resistant continuous floor done that way. Was something like 100' x 100'
