Process of chemically melting PVC pipe and fittings together?

• A. Solvent welding
• B. Soldering
• C. Gluing
• D. Crimping

Answer: (A)

Solvent welding is the process of chemically melting PVC pipe and fittings together. The cement contains solvents that soften the PVC surface. When the softened surfaces are pressed together, the polymer molecules from the pipe and fitting mix and fuse as the solvent evaporates, creating a strong, leak-tight joint. This method relies on chemical fusion rather than external heat or ordinary glue. Soldering would apply heat to metal, not appropriate for PVC and would damage it. Gluing with generic adhesives doesn’t produce the same true fusion of the plastic surfaces, and crimping relies on mechanical pressure rather than chemical bonding.
