photo left shows how a leak detect solution found a 1 to 2 CFH leak.
We plugged the hose end and slightly loosened the fitting to produce this
leak. The ball in the flow gauge was just off its seat. A simple
leak detect solution easily found the leak. The bubble test solution quickly
produced bubbles. Using a leak detect solution is better than soap. It
will produce smaller bubbles and more accurately define smaller leaks.
It also will not corrode the brass fittings.
Ultrasonic leak detectors can be used to find leaks, we have and use one in our consulting service. However we have
found that a welding or cutting arc, MIG, Stick or
interferes with the reading. Arcing of electric motor brushes also confounds
the gas leak noise. The amount of noise these and other machinery create
will be detected with an ultrasonic tester and obliterate any leak sounds.
It must be used
when these devices are not operating.
Did you know
if shielding gas is leaking out of a hose or fitting, air and moisture are
leaking (diffusing) back in! Sounds strange--it's true. Our Lean Welding Manufacturing Learning Program explains how John Dalton in 1776 defined the law of partial pressures that explains why the air flows in that direction.
