Huh? PVC cement is a solvent glue.

it's closer to welding than gluing...if you think about it!

No. "Welding" is the fusion of the same materials. PVC cement is not PVC,
so it is not at all like welding, because the joint filler material differs
from the bulk material. More like brazing or soldering, if you want to
analogize.

The solvent melts the plastic so that it fuses to itself. The solvent
acts as heat to soften the PVC. That is not a glue property...with all
do respect.
