Air Leakage Testing

When Sealing is done then we have to check if there is leakage in the sealing or welding connection or in pole post brazing. This can be done with the help of Air leakage Testing Machine.

This system functions on the principle to pressurize cell at certain air/inert gas pressure and this pressure is hold for certain period, if drops below required pressure setting then it is made certain that this cell is leak. This can be done by individual cell one by one or alternative cell i.e. cell no. 1,3,5 then 2,4,6. Rate of Pressure drop also determine extant of leakage.

There are Three types of air leakage systems available mainly:

  1. Manometer
  2. Air Tester hand held
  3. Air Leakage Testing Machine

Manometer is very old technology & this cannot be used for fast operation.

Air Tester

  1. Air Tester is used for small production capacity. This device is manually hand held and batteries are placed in line to get best results. Individual cells are checked by allowing air pressure to enter cell through venting of cell and stopping air pressure then holding the air pressure at venting of cell. If pressure is dropped below set value this is viewed in pressure gauge, Air Tester is holed for certain period if it drops more than required pressure then there may be air leakage due to following reason.
  2. Leakage in cover to container sealing in out side edge, this has to be ascertain by hand or soap water bubbles then sealing fixture or sealing machine has to be checked.
  3. There may leakage in partition sealing to cover, this has to be ascertain by plugging of vent of adjacent cells then also sealing fixture or sealing machine has to be checked or partition may be twisted.
  4. Air Tester may not be held properly either it is inclined or sealing washer be deteriorated.
  5. There may be leakage cell to cell leakage but not from sealing, it can be from welded L connection at partition.
