Welding a Cast Iron Water Pump Housing

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.

Chris Wantuck sent us a disc showing his repair of a Lincoln water pump, using our 77 electrode.

 

The cast iron exhaust manifold prior to welding.
 

 

Another angle
 

 

As you can see the cast iron has several broken pieces.
 

 

After securing the part in a jig, Chris is ready to begin welding.
 

 

In a matter of minutes, the cracks have been eliminated.
 

 

Now the water pump is ready to be finished.
 

 

After grinding down the excess material Chris is ready to make the final repair.
 

 

Corrosion has eaten away the cast iron flange.
 

 

By simply using Muggy Welds 77 electrode and a grinder, Chris's part is good as new, and ready to reassemble.
 

 

TIPS:

 

For best results weld one inch at a time to keep from overheating the cast iron.

 

Gently pre-heat the cast iron if possible, no need to get it red hot but it will lay flatter when you first start your bead and preheating removes moisture out of the cast to prevent pinholes.

 

For best results clean and bevel the cast iron before welding.
