Silver Solder Brass to Stainless Steel



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.

SSQ-6 is commonly used to silver braze brass to stainless steel, due to its ease of use and convenient syringe applicator. Muggy Weld customers have been utilizing SSQ-6 for projects requiring paste inside or under the metal to metal contact, in areas where rods may not flow.


Simply apply SSQ-6 to the bolt before screwing on the nut.


SSQ-6 is applied to the threads of the bolt before soldering.




The brass nut is in place and ready for the SSQ-6 application.



We apply more SSQ-6 to the top of the nut to achieve higher strength.




The bolt and nut are broadly heated with a propane torch until the SSQ-6 flows out completely.




The finished solder is a weld strength joint that requires no machine work.
