Hello again jsdwelder, hearing your latest information, you may very well be out of a code type situation and into more of a verification and procedural type of scenario. Meaning that you are more so trying to verify that by using the procedure that you come up with you will be able to apply this layer of hardfacing in such a manner that it won't crack and chip, fall off, or fail in any other way prematurely. You should likely base your PQR parameters on the wire manufacturers recommendations for welding parameters and any pre-heat, interpass, or post-heat considerations. Also pay close attention to their recommendations for application thicknesses. Once you have come up with a satisfactory application regimen, make the necessary notes on your WPS. Just a few thoughts for consideration. Best regards, Allan
