Weldment test system

A testing system for testing the fluid integrity of a unit under test including a piping with opposed fittings thereon, comprising:

• a cabinet having an internal shelf, a fluid test circuit region on a first side of the internal shelf and a test region on a second side of the internal shelf;
• a fluid test circuit with first and second pipes extending from a first side of the internal shelf to a second side of the internal shelf, the open ends thereof distal to the second side of the internal shelf positioned to connect a unit under test thereacross, the unit under test comprising a tube having first and second connection portions on the opposed first and second ends, respectively, thereof, connected thereacross, the fluid test circuit comprising:
• a first nitrogen source line selectively connected to a first IPA tank through a nitrogen selector valve, to selectively exert nitrogen pressure on isopropanol in the first IPA tank;
• a second nitrogen source line selectively connected to a second IPA tank through a second nitrogen selector valve, to selectively exert nitrogen pressure on isopropanol in the second IPA tank;
• the first nitrogen source and second nitrogen source each further including a first subline and a second subline;
• a fluid circuit, comprising a fluid line circulation circuit;
• a first drain selectively connected to the fluid line circulation circuit through a first drain valve;
• a first IPA tank connected to the fluid line circulation circuit through a first IPA line and a first IPA valve, and a second IPA tank connected to the fluid line circulation circuit through a second IPA line and a second IPA valve;
• a second drain connected to the first IPA tank through a first IPA drain valve and the second IPA tank through a second IPA drain valve;
• a first IPA vent connected to the first IPA tank through a first IPA vent valve;
• a second IPA vent connected to the second IPA tank through a second IPA vent valve;
• a first water line selectively connectable to a water source and to the fluid line circulation circuit through a water valve;
• and
• a drain selectively connectable to the fluid line circulation circuit through a drain valve;
• wherein the fluid line circulation circuit is selectively configurable to flow water, nitrogen and IPA through the unit under test.
