We currently have a rectangular shaped water tank made of polypropylene. The tank is a large tank designed to hold 3,000 and 4,500 gallons of water. The majority of the tank welds are welded using extrusion welds.
We are looking to redesign the tank and the new tank would have more complex weld joints (v-groove, double v-groove, lap welds). We don't fully understand why the current welds meets our needs, but they do. I'm trying to understand what occurs when you weld PP and how the strength of the weld will change with the new weld configurations in efforts to predict that the new design will meet our requirements.
I have taken some cross sections of the current weld design and am unable to see any effect of the weld on the parent material, like you would see in a metallographic sample. Are there other ways to evaluate polymer welds?
Any information on welding PP and how to design proper joints would be appreciated!
Thanks in advance for your assistance.
