Solvent welding is a method of joining plastic pipe, usually used on PVC or ABS to achieve a high strength joint. In the process, the plastic in the joined surfaces is chemically melted, and joins together to a solid piece when the solvent evaporates. A properly made solvent weld will have a pressure rating equal to that of the individual parts. The joints will take some time to achieve full strength, cannons should be left to dry at least 24 hours before use.

Solvent vapors are flammable and hazardous to your health, work should be done in a well ventilated area and away form ignition sources. The chamber of combustion and hybrid cannons should be vented before testing the ignition, accidents have happened when solvent vapors have ignited in newly constructed guns.
