You don’t feed it from the top. You bring it from the side but your wire is still inside the pipe not outside the bevel. There is a video on carbon where the guy does it that way. The big thing is the wire being on the inside. Hope this helps.
Alan klem haha and lol smartass obviously you don’t know much about welding. A lot of people would like to see that type of video I’m not saying he wouldn’t pass it but it doesn’t matter how many plates you weld on or beads you lay down one of the real tests is bend test. Your welds can look amazing and still fail and sometimes look like shit but get lucky with a root and bit of penetration and pass.
5:09 gotta learn how to use ur left hand so u don’t have to crunch over like that if you can use your left hand 6g will be your easiest weld you make !
Nice weld. But the way you brush that don’t let Travis see you doing that. But some more info plz, what is duplex? Is it a form of stainless? What size rod are you using is that rod the only rod that should be used on that material? How many amps are you using is it 100% argon?
Duplex and Super Duplex are basically high chrome versions of stainless. Very corrosion resistant because of the extra chromium, but ridiculously expensive. (Also high nickel content) In my industry, under basic ASME Section IX pressure vessel codes, it can be pretty tricky to keep compliant. There are two types of steels. Ferritic steels, and austenitic steels. Individually they both have their weaknesses, but the theory of Duplex is to have approximately a 50/50 matrix of both Ferritic and Austenitic stainless steels, hence the name Duplex. The puddle behaves more nicely than other high nickel alloys like Hastelloy or Inconnel, but there is similarity. The tricky part is that it's very sensitive to excessive heat input, and time spent molten. The 50/50 balance has to be kept within a certain range after welding, so you can't be too slow. I believe our code allows 20%-30% balance in either direction before it must be rejected. If it's too far one way, it won't be corrosion resistant enough. If it's too far the other direction, it's as brittle as glass, So the balance is crucial. The longer you keep any one puddle molten too long, and/or without adding rod to maintain a good mixture, you facilitate the austenite and ferrite to precipitate out of mixture of each other, and ruin the properties of the material.
@@evanchi9460 you are correct sir but also it has nitrogen in it and like you explained if heated to a higher temp.the nitrogen evaporates leaving just a normal 300 series stainless steel he failed also to mention the cooling process you cannot get this alloy to hot or your in problems.
You guys usually make great videos but this is not one of them. The camera work is horrible. I can barely see the puddle when you are putting in the root. And why are you using a foot pedal when the majority of people welding duplex won't have that option?

What were your amps for root and then your hot pass or cap?
All well and good backfeeding on a 2" pipe, but how are you going to do that on say an 18" or 24"👍

Why make a video and not discuss your heat settings?
Very impressed with this one..... freehand the root like an old dog.... great job!!!!!
i like how snappy the dynasty is when you were tacking
Good welding, great video, great.
You are champion hagojibi
What setting you used man
How many amps on the root run please?
how many amps u running on each pass?
I think a lot of people would like to see some stick and flux core open root or backing strip and actually see you bend test them to see the results.
Weld Weld they already have plate videos and why would you need to see a bend test? You think they won’t pass it? Lol

I had a open root test one. I didn't even know those were a thing. I'd really appreciate a video on it
How many amps???
Dear brother please told 2 inch ss rote pass current of you use
How many ampere root pass and caping?
Why you don't show machin power

There's no foot pedals in refineries...we need temperatures
Amps?

He said which rod....
Thats the way that travis brushes

Filler cord
nice 👌👌👌
Nice video
I never see them welding 6Gr in a restriction box. Always out in the open easy in the open
👍👍👍👍👍
обратный валик неровный за то нет утяжки у вас требуют обратный валик
Root no GOOD

I dont think his using a foot pedal bud.

This video was pathetic. Should of let halmar do it..!!

No good quality of your root pass
