Brazing Aluminum Through Oil, Paint, and Dirt

Testimonials

Mike,

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.

 

aluminum welding and metal repair

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.

An aluminum air conditioning return loop is welded with Super Alloy 5 aluminum rod and flux. Notice the filler rod's perfect color match in comparison with the parent metal--you cannot see the difference.

 

TIPS:

 

While it is not necessary to pre-clean the aluminum before making the repair, a clean part will  decrease the amount of flux needed. 

 

Notice the technique: As soon as the rod began to flow, the heat is removed very quickly to avoid overheating the base metal.

 

Turn down the oxygen when working on thin aluminum parts.
