Removing Cad Plate
Removing Cad Plate
(OP)
Could anyone point me in the right direction to a specification or a in house procedure I can plagiarize, to remove Cad Plating. The situation is; we have parts Cad Plated before they where welded, and I need a procedure to reference for the Engineering Order. If I could get assistance it would be greatly appreciated.

the parts to our plating vendor and will be using
ammonium nitrate to remove the CAD Plate. Then they will be
welded and Cad Plated per ASTM B766.
swall, you state the parts should be stripped and then to have hydrogen embrittlement relief. Isn't that done after?
Cad Plating.
This is what our note reads on the drawing.

Hydrogen Embrittlement Relief
Again thanks!

Most aerospace specifications require hydrogen embrittlement relief after removal of cad plate by ammonium nitrate, unless re cad plate can be guaranteed in the four hours following stripping.
