July 29, 2015 – Sanford, Florida – The Quality Department offered a solvent welding training session by Weld-On representatives. The session included safety precautions, set and cure times, causes and repairs of failed joints, and a hands-on test for each participant.
First, the reps laid out the basic principles of solvent welding:
- The joining surfaces must be softened and made semi-fluid.
- Sufficient solvent cement must be applied to fill the gap between the pipe and fitting. Applicators (daubers and swabs) should be equal to half of the pipe diameter.
- Assembly of the pipe and fitting must be made while the surfaces are still wet and the solvent cement is still fluid.
- Joint strength develops as the cement dries.
That’s just the beginning. To avoid failed joints or leaking pipes, you’ll want to follow all of the process steps in the correct order. For example, apply primer to a joint, then the pipe, then a second coat to the joint. The order—joint, pipe, joint—will help fill the void created due to the beveling in the joint.
General Superintendent Ed Sly held a similar class on one of his job sites, “I’ve been fitting PVC pipe together for more than 25 years and I still learned a lot of things I didn’t know before,” he said. “The class was informative and educational.”
