Experimental Analysis of Mechanical Behaviour of Poly Vinyl Chloride (PVC) Plastic Welded Through the Fabricated Experimental Set-up for Hot Air Welding

The present work is based on the motivation to bring the technique of hot air welding so as to weld plastic materials such as poly vinyl chloride (PVC) etc. As the hot air welding is an environment friendly joining process. Through this paper an initiative is taken to introduce this recent technology of hot air welding in the workshop level because hot air welding of plastics is not common in general. In the present work, we have fabricated hot air welding setup for exploring and sharing such a nice invention to humanity given by Robert. C. Reinhardt in 1940. An initiative has been taken to fabricate low cost setup of hot air welding because the actual machine of hot air welding is very expensive and costly. The experiment was performed on the fabricated setup and the samples of PVC plastic were successfully joined through hot air welding technique. After successful joining, the welded samples were tested for tensile strength, hardness and cross breaking load (bending test) and it was found that the samples were safe after the testing which shows the reliability of welded joint and opens the door for young minds to work further on this technique.
