Dear

The cold repairs are anything you use for crack fill and bonding is the cold repairs. In this case you may like to try CORDOBOND, DEVCON, even THISTLE BOND. you can use anyone of these products. After curing the same can be even machined for removal of unwanted material and get you smooth surface.

Thank you but I have machine shop to machine back to OEM and also a Schenck 6400# balancing machine to balance.  My issue is the welding process needed for this material.

What would be your COLD suggestion?

Respectfully,

Dear

 

The impeller rings not to be welded if there are more cracks, because you can't get surface perfection then you will experience the imbalance and the impeller will further get damaged and ultimately purpose will not be solved.

Yes, only one option if you want to go for cold repairs in case of emergency and nonavailability of the resources for building up.

Good luck.

Dear experts,

 

Have several cracks on the wear rings of a Goulds pump Impeller.  PMI has been performed and rings have been identified as --17-4 Ph.  The impeller itself is a mild c/s.

Have no references on welding these two metals together?  Any ideas or procedures?

 

Respectfully,
