Couple of Questions from Beginner

admin

Hi all,I know I should post this in the 'Introduce yourself' section but I have a general question as well and this is my first post;I am a soon to be retired military pilot out in Las Vegas, NV who is getting hooked on welding. My brother and cousin both pipe weld back in Texas and they got me hooked on learning this skill and now I am determined to learn all aspects from Gas to Tig and get good at them. -Here's the question: what makes a rod an all position rod? I know the number designates it as so, ie. E6013 rod the third numeral '1' meaning all position but what is the difference between all position and flat or horizontal only rods? -Also, anyone out in Vegas willing to spend some time and rods giving basic instruction to a beginner?
Reply:-Also, anyone out in Vegas willing to spend some time and rods giving basic instruction to a beginner?send a p/m to MAC702he's in that area i believe.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:copy Zap,and thanks for the craniums up on MAC702!
Reply:Qoute from ESAB, http://www.esabna.com/EUWeb/AWTC/Lesson3_7.htm"Characteristics for Welding Position - It is the addition of certain ingredients, primarily  titanium compounds, in the coating that makes it possible to weld out-of-position , vertically, and overhead.  Slag characteristics, primarily surface tension and freezing point, determine to a large degree the ability of an electrode to be used for out-of-position work"That's not a huge amount of info, but there's quite a bit more "background" info in this ESAB link, for those who like to know WHY.Why is the moisture content of 6010 much higher than 7018?What element is added to a basic 6010 formulation to make it 6011 and allow it run on AC?What makes the coating so much thicker on 7014 and 7024 and what's the purpose?

Reply:I flunked Science  But can stick weld  There is nothing like experience to show you and tell you whats up.  Pulser I'm not ragging on you there is a lot of good information there and am gong to read it myself. I myself don't get things when I read usually. I see something that says something wont work and its kinda like a challenge to see if it does. Almost like those unbreakable light switch covers you can buy.. HMMMMM unbreakable, sounds like a challenge to me. I would get some rod and see what you can do with it.Drivesector Hobart Handler 140Hobart Handler 180Ready Welder 2Hobart Air Force 400Airco Stinger 225Of all the things I've lost, I miss my mind the most."OZZY"
Reply:Thanks Guys,I was just curious about the rods and thanks Pulsar, I will check out the ESAB site and read. I like understanding the why or theory of something as well. But I truly understand all the book knowledge in the world won't help me learn to weld unless I burn up some rods, gas and metal. In my case a lot of it.It's the same with military flying, you have to have some background theory before you sit in the cockpit. It makes things with students go way faster!Dean
Reply:Actually I checked out the site, it looks like a lot of fun. Thanks for the link Pulsar, I backed up to the main site, very good info to be gleaned. And Milspec, reading is good accompanyment to experience; nothing works as well as mixing things up. Kinda like a mutt being the best dog I ever had. Hands on, study, talking to other welders in different disciplines. It adds up nicely.   Good luck!!If you don't have the time to do it right, then you definitely don't have the time to do it over.

Reply:I saw pulser's reply as a answer to the original question and some insight as to what other info was at the site.  I appreciate all the links people add since I'm the curious type and then wonder what else is at the site they point out.I appreciate all the info/time everyone offers here. Now if i could only retain/apply 5% of it I might know what I'm doing.Hobbiest hack
Reply:He PM'd me, and I replied.  Haven't heard back yet.  Seems like a neat guy to have around here for sure!The other term for an all-position rod is fast-freeze.  This is because the puddle freezes (solidifies) more quickly and doesn't fall in your face while welding overhead.  And some fast-freeze rods freeze faster than others, too.

Reply:And an interesting thing to keep in mind is that most auto-darkening hoods clearly warn against their usage in welding overhead...

Reply:One would assume they don't want any liability resulting from damage from spatter (or worse) falling and melting through the cover plate and damaging the lens.
Reply:Most of my welding is overhead. In the six years I've used a speedglas hood its never been a problem. It does say not to do it in the instruction book though. A coworker bought a new Jackson hood, I'm not sure which one though, about 2 hours into the first day a red berry got through the outer cover and warped the corner. It ruined it. No warranty for heat damage.You should read the book that comes with the hood, ever if you don't follow the advice.
