Many thanks.
I can't change the hose. I'm trying to explain how when there is a loose joint that air gets in to the tube and increases the air content within the tube, as this air content is contributing to porosity problems.
I can tighten the seals etc, but what I'm trying to get is a...
OK, I hope this helps:
Argon bottles 99.997% pure & @ 2000psi
Connected to a regulator that turns it town to deliver 15cubic four per hour through a 6mm I.D hose to a welding unit
Hose is basic flexible clear plastic hose (garden hose spec).
The pressure in the gas bottle drops as the gas is...
Many thanks for all your replies.
For clarity, the issue is that a soapy solution over joints in the line from the argon gas bottle to the welding unit is bubbling (at joints). Oxygen is getting into the pressurised argon line. This oxygen is a principle (but not the only) cause of porosity...
How does oxygen get into a pressurised gas line at a leak?
When you can see leaks at a joint in the line between bottle to welding unit joint (after adding a soapy water solution), can anyone help provide a technical reference of how the air (oxygen) gets into the line to be one of the causes...
