you won't get much help with that attitude.
I've welded pipe for 30 years. I don't need to get on the internet to ask how to weld on the bottom.
You know how to make the bottom look like the top? **** up the top, that's how! Idiot
Thats What my inspector tells me all the time.LOL
LMAO!! Now that's funny right there!
ZCat,
Dang-it, you beat me to the draw! That was gonna my "suggestion".
Some people....
But, I will answer the post by saying that .... you answered your own question. It IS EXACTLY like the top.
Get off the computer now and go practice till you can understand what I'm saying.
Come back then and be more civil. We try to help each other out here...not insult and demean.
you cant approach the bottom as you do the top thanks for all of your smart ass remarks but not to much help
THE MAN SAID PRACTICE
what works for 1 person isnt gonna work for another
i know people that long arc the hell out of the bottom
i know people that go down 5 or ten
and i know people that run 5 or ten hotter on the bottom
its all in what works for you
I too had problems with the bottom when I first started, and I would get the same response when I would ask other welders. "It's the same as the top" I would think to myself screw you if you don't want to help me. But then on my 2nd job I welded for 14 hours a day nonstop and guess what. After welding 40 or 50 I found myself welding the bottom the same way I welded the top and it looked just as good. No more turning it down, no more stepping out, just stay in the puddle and take around. So practice is the best thing. I know how frustrating it can be but stick to it and it will come together.
keyholen,
34 minutes was the time between our posts. That is hardly enough practice time to absorb the advice given. The more you think about it, the harder it is. Everything is exactly the same, rod angle included. It is best to learn how to make an entire pass around the pipe without adjusting the heat. Your not always going to have someone there to hold the remote for you and since you are new to this procedure, there is little benefit to be gained by stopping to go fine tune the amps everytime you get past 3 o'clock.
If your welds are perfect on the top half. Then stop practicing on the top half. You've got that part down. Weld the bottom, then roll the pipe 180 and practice on the bottom again. Do this on 20 pieces of 6" pipe and then if no improvement, you will at least have some specific details of what type of problems you're encountering and then perhaps the posters in this forum can be of greater assistance.
Ya know, the great guitarists practice till their fingers bleed. Welding is just like any other art form or craft. It comes easier to some more than others.
Just relax, go with the flow, and don't get too many sparks down the ear!
drag the rood or 90 degees never keep it forward keep it choked in.
Fuc* up the top to make it look uniform. Damn thats sweet.
I love when a guy already knows everything and still ask stupid questions. Why would he practice when he can just go online and learn sometimes I am amazed at how stupid some people are look at the response and for once use your brain instead of your mouth.
That is cute! I will have to add that to my own smart a** remarks.
But the advise given is only halfway. You weld the top like the bottom, just upside down.
I always thought that was smart a$$ until I finally got my bottoms.
If you are using a side to side weave on the top, use it on the bottom.
If you are using circles on top, use circles on the bottom.
As you move down the joint, you are fighting gravity all the way. You MUST know and learn puddle control. You can push the arc and puddle if you know how to control it. Practice using the same heat on the bottom as you do on top. It is a matter of speed, motion and arc length. I have seen few welders who do it the same way so you will need to develop a technique that works for you.

Thanks for the advice . I have been welding pipe pretty solid for about 2 years now mostly 2 to 4 inch , just recently moved to 12 inch and bigger, moved to 3/16 70+ it just seems way more different to me .
When i get to a certain point on bottom rod seems to start blowing chunks , i keep in the puddle i get to much hang down ,long arc i seem not to have much control of puddle . side to side weave seems to undercut sides and ridge in the middle , i run a vantage 400 cap at 132 to 140 at 4to 6 on crisp side
Try turning your arc control to 0
thanks ill try, one more question when adjusting arc does it directly affect amperage
I take it your talking about the cap. Hows your root? When weaving pause on the toes and pass across the middle that will help keep it more uniform.
Sounds like you're running too cold for 3's on that size pipe in my experience - I have a 300 vantage w/ duetz.. an amp or two one way or the other makes a difference in the way it welds - I normally start out the day around 148 and end up running hard on pipeline around 152-153 once mine gets warmed up - about 1000 hrs running time so far - that's on 6" pipe x .237 wall - arc control maxed on crisp side (I can fine tune it w/ arc control to a point) - keep a close arc running down sides.. open up a bit as necessary on tops / bottoms - windy crank it up a bit more and shove it in to the weld closer yet. It will change a bit from there on larger diameter pipe... in my experience. Frustrating is when you don't work it hard enough to warm up - (like when you have an inexperienced hand you're trying to wait on - ) then it's not as consistent - love the machine as an all around tho!! Wouldn't trade for anything else I've run so far - Lucky
Practice on plate. It's cheap and there's no prep. Bend under and run the straightest beads you can. If you can cap nice and straight over nothing to follow, then pipe seems much easier when you get back on it.
Keyholen ,
I'm not being a smart a$$ , but PRACTICE is the only way to master your issues . These guys know what their talkin' about . Your two years is just enough to figure out that pipe is round and plate is flat . You need to play with your heat and speed and position . I've been weldin' for 19 and I still learn something every day ! I still practice ... every day . I weld on my days off and try to stay sharp ... and learn . Don't take it personal but you did come off cocky . Ease up and listen ... apply ... and repeat . JMHO for what its worth . Good luck !

oh man i laughed pretty hard at that one. you should run for political office because that problem solving style is their favorite....thanks for the laugh z
funny
and keyholn just keep at it and dont give up.
