These pics come from a new aerospace test facility that they are constructing at the University of Notre Dame. The SSF-6 is working great.
I am attempting to make all of these fittings air tight as they are used for pressure measurements. We can¹t have any leaks. I had very little warpage of my base metal and I think this is really going to work out very well.

Copper has a variety of uses, and can be found in water piping in nearly every building or home in North America. Copper is also used in A/C units, refrigeration, and is a good conductor of electricity.
First, pre-clean the area you will be soldering with a wire brush.
Apply the SSQ-6 silver solder paste by pushing the plunger on the syringe
Broadly heat the area with a propane torch, then flow out the solder by moving your torch from side to side.
Clean the finished bond with water and a wire brush. The end result is a beautiful finish that is as strong as an arc weld (over 80,000 psi)
Although we did not add SSQ-6 to the backside of the copper, it flowed perfectly, front to back, with no pinholes or porosity.
