The hot-air welding technique utilizes clean hot air to preheat the duct material and CPVC welding rod, while pressure is applied to the weld area as the rod is guided. This joining method results in the surface molecules of the parts being joined to fuse together at the weld seam. Only welding rod produced from CPVC material is recommended for this joining process to ensure the highest system integrity. All welding should be conducted by personnel adequately trained in the art of hot-air welding thermoplastics. Detailed information concerning CPVC welding and fabrication is available.
