ABSTRACT:
A method of testing a weld joint interconnecting two thermoplastic parts comprises forming a sealed cavity around the weld joining the parts and applying a predetermined test pressure to the cavity to determine if there is any leakage thereof. The device of the invention comprises an additional wall structure which defines a seal cavity around the weld joining two thermoplastic parts and which is advantageously made by an additional weld or welds which forms the test cavity surrounding the welded joint to be tested.
