Why do I always have pinhole leaks in my welds?
No matter how hot I run the weld and how good it looks (even if you slice it open), it seems that I always have pinhole leaks anyplace where I start/stopped a bead. Not porosity, it doesn’t happen in the middle of a bead, always where 2 beads overlapped, usually where they stopped or started.
What can I do if my welding connection is leaking?
A spray of soapy water on the connections can help you find leaks. If the gas is flowing too fast, that’s also a problem because it creates turbulence.
How big is a pin hole in a weld?
We are currently getting a pin hole (crater cracks ??) at the end of the weld bead. The hole is approx. 1/64 – 1/32 in size and by the naked eye there is no apparent cracks around the hole.
Is it possible to get pinholes in TIG welding?
TIG welding is an excellent method for joining metal, and it can make beautiful welds. However, if you aren’t careful, you can get pinholes in the bead from TIG welding. How to stop pinholes when TIG welding? The best way to prevent pinholes when TIG welding is to avoid some of the common causes of them, such as:

What should I do if I have a pinhole leak in my pipe?
If you do have to repair individual pinhole leaks, we recommend adding a water filtration or softening system to prevent future pinhole leaks. Water filtration and softening reduce hard water deposits, which can cause leaks over time because they act like sandpaper against your pipe’s walls.
How old is a pinhole leak in a copper pipe?
This is your first pinhole leak, or you get very few leaks per year. Your copper plumbing is less than 20 years old. Copper pipes can last 20-50+ years. So if your copper piping is less than 20 years old, it’s likely not fully corroded. Your leak is located on a solder joint, elbows or tees.
