Cast Iron Exhaust Manifold Brazing with Silver Solder

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.

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.

Cast Iron exhaust manifold cracks are common problems repair shops face daily. Due to the expertise usually required when welding cast iron, many shops wont even attempt to repair the part. Unfortunately, new manifolds can range from $150 to $1200--and many of those replaced manifolds could have been saved with SSF-6 Silver Solder.

This cast iron exhaust manifold has first been prepared by beveling the cut.

 

 


Using a size 1 tip with an oxy-acetylene torch, Mike easily brazes the cast with SSF-6 Silver Solder.

 

 


The final result is a beautiful weld, with 70,000 psi holding strength--the same as an arc rod.

 

 

TIPS:

  • Flow out each drop of rod before depositing more.
  • A flat braze will result in the best seal.
  • Broadly heat base metal to create an even flow.
