Welding p91 pipe

admin

I am looking for some help with welding p91 pipe . I started a thread about 9 chrome but only got 1 reply so I'm trying again.  Just need as much help as I can get as I'm new to welding 9 chrome. Tig root n hot. Stick out. Argon purge
Reply:Can't remember enough technique to be helpful.  Only that the amount of preheat and inter-pass temps required cursed heating coils and insulation that always got in the way of easy gliding movement.  Seen this page?.....http://www.steamforum.com/pictures/G...0R%2010-05.pdfLast edited by OldSparks; 08-12-2015 at 11:50 AM.
