Does anybody know the P NUMBER (or S number) FOR TOOL STEEL W1 for procedure qualification?

Thanks

Thanks for the link.
Checked, doesn't seem it is on it.

 

RE: P NUMBER FOR TOOL STEEL W1

well tool steel is really not real weldable, least I wouldn't try it.

I guess some folks are set up for it

andyweld;
There is no P-No for this steel. Why do you need one? Just list the base material designation as W1 Tool Steel on the WPS.  

RE: P NUMBER FOR TOOL STEEL W1

(OP)
Thanks for the reply. One more question, normally what filler material is used for TIG welding this material?

RE: P NUMBER FOR TOOL STEEL W1

andyweld;
This tool steel is a high carbon low alloy steel that can be welded with local preheat only (300 deg F). I would use a carbon steel filler metal or Inconel (Inco A) depending on the function of the weld.
