Nice work so far. I really don't have an answer for you as my knowledge of welding is very limited. Personally I would TIG it. But you may want to hop over to Welderzone and ask there. Being a boiler, I would be very careful. Eric |

Very nice work on the plug, I to would have to say that if you are doing that nice of TIG, why do any other. On a side note, you can all ways take some scrap material you are using for the boiler. Prep it and weld it then cut it thru the weld to check out your penetration etc. I posted some links for a boiler code and another forum with boiler info on it. Here in the resources section http://madmodder.net/Forum/index.php?topic=200.new#new ;D |
