Does anyone have any sucessfull mehtods for locating a hairline crack in a stainless weld?
The tank is a typical double wall conditioning tank. There is a very slow leak in, what I feel, is a fatigued weld. A step by step process that we are trying is yielding slow results. The leak only shows itself under pressure. Naturally, this limits the ability to observe the interior of the tank. Attempting to pressurize the insulated space between the walls was not as sucessful as desired. At that point we tried the simple method of soapy solution over interior welds hoping to see some bubbles...no bubbles!
Any thoughts would be appreciated.
