Stainless Pig Roaster

admin

Just got a new Maxstar 150 STL, Never really TIG'd before, but an awesome Boilermaker I work with who is a really great guy and a great teacher (ex navy welder, PA coal Miner  ) and I have started a stainless pig roaster project. What a great way to learn - hog, beer and friends are the reward! Anyway - pics of the project and my new guy welds. Big junky weld done @ 100 -105 amps, 1/8 309, the others@ 60 amps, no filler. Roaster is 5' wide 30" deep 11 guage 304. Phone pics are pretty bad, and I think I have the knowledge, just not the skills yet, to improve. Attached ImagesJust another clown trying to be cool

Reply:Nothin' like going whole hog on your first tig project It looks good so far. Having a good teacher really helps. Have fun.
Reply:Looks good so far!Any reason to worry about warpage w/ only 11 gauge?"...My pappy was a pistol I'm a son of a gun...""...God is great, beer is good, and people are crazy..."

Reply:The project looks like it will be a good one.  And expensive one!After looking at your welds, and understanding your experience, I would try to put less heat into them.  The more heat that you put into it, the more that the nickel will get "cooked out."  The nickel helps to keep it from rusting.If you are traveling at the correct speed, with everything going correctly, the finished weld will look like there wasn't any heat put into it.  The weld will be shiny.-Rhyno07 Fowler 200D65 RedFace04 Miller TB 302, 22hpMiller 12RCMiller HF 251-1Lincoln SP135HyperTherm PM 380and a few others...

Reply:Thanks for the advice Rhyno. I haven't quite got the speed / heat ratio down yet, I'll give her another go today with less heat and see how it turns out. I got the stainless heavily discounted from a fab shop that we use for all of our stainless contracting at work. It came from their remnant pile and the shop foreman rolled it for 50 bucks, so it isn't too bad as far as $$ outlay goes.Just another clown trying to be cool
Reply:That is a way cool project and I admire your trying it with so little experience.That finished cooker will cook differently then a steel one-stainless doesn't conduct heat so it will react like the its been insulated-probably need a smaller fire to get the same results. (glass blowers use a stainless steel pipe so their lips don't get burnt.)

Reply:I played around with scraps today and I see what you mean. I got "hung up" a bit and held my puddle too long and the color change that occurred from a silvery yellow to black was a matter of seconds. I am in love with this process, I wish I wasn't so afraid of it for all this time. I appreciate the help guys!Just another clown trying to be cool
