Hey guys I'm looking for information on TIG welding H13 tool steel for repairs. I'm getting mixed answers and like to see what some of you have to say. What filler rod should / can I use and is it necessary to preheat ?Ultimately the piece is going to be heat treated. Does a stainless or mild steel matter at this point ? It's for and injection die mold. Thanks in advance.
Reply:that one is not gonnabe fun. Preheat to 800/1000F (430/540C) minimum. Maintain above 700F(370C) during welding. Cool to 150F(65C) after welding. Temper 25F(15C) below original tempering temperature. (1000F(540C) Minimum) and use H-11 filler.got that from---http://www.simplytoolsteel.com/H-13-tool-steel-data-sheet.htmlmiller thunderbolt 250vlincoln square wave tig 175 prolincoln idealarc mig sp250everlast tig 210EXTeverlast power plasma 50chicago electric (hf) 130 tig/90 arcchicago electric 90 amp flux wire3 sets oxy/acet
Reply:We use a Eureka Marweld250 to rebuild cores, cavities and cams.. I can highly recommend it, machines just like H13 after welding and heat treats well..http://eurekaweldingalloys.com/uploa...0107264058.pdftackleexperts.comwww.necessityjigs.comhttps://www.facebook.com/groups/mach...dingequipment/
