Soldering Aluminum at 350°F

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.

Super Alloy 1 is exceptional for soldering 2 light gauge aluminum pieces together.  Prior to soldering, clean the parts with emery cloth, sand paper, scotch brite, wire wheel, or a clean wire brush.  Pre-cleaning is important when using Super Alloy 1, as this enables the rod to flow deeper into the pores of the aluminum.

 

 

After preparing the aluminum, add the flux by dipping the Super Alloy 1 rod into the flux bottle, then paint the flux liberally onto the joint or area to be soldered.  Always dip the rod again before adding alloy to the part; it is imperative to use an adequate amount of flux for a perfect repair or finish, especially if the joint needs to be air or water tight. 

 

Since aluminum cools very quickly, lay a wire underneath the part to ensure even heating (especially if soldering on a steel table).

 

 

Heat both sides of the aluminum evenly to help the Super Alloy 1 flow through to the backside of the piece--the solder will lay flatter achieving a perfect solder fillet. Avoid aiming the torch directly at the Super Alloy 1, since it melts at a low temperature.

 

 

TIPS:

 

Let the part cool down on its own. Pouring water on the part weakens the solder joint and may damage the solder fillet if still in the liquid state.

 

After the aluminum has cooled, use a clean wire brush and warm water to remove the flux.
