I live for oil and gas it’s truly my passion. so al is the ultimate manuals guide lol

Omg 😍😍 that is so amazing, this is what I was most looking forward too.

[@paulmeersa7162]

Does that say API 5L on the pipe? I had not realised API 5L covered 9% Cr pipe..?? It doesn't tend to rust too easily either. Maybe just the wire is 9 Cr V...?

[@georgiojansen7758]

thermocouples not good, just tack temp wires on the pipe ,much cheaper also,, i did that 25years ago attached to a chart reader, to avoid going over a temperature, just my 2cents

[@SR-vk5pd]

What is pipe material and welding process? If pipe is 9chrome Why Purging gas is not used? Heating system is good, however is it useful when using positioner or turning roller?

[@johnjacobjingle8302]

Would if liked to see the root.. kind of curious..

[@ypaulbrown]

what size wire? what volts on welding machine, thanks,,,,,kool video.....hot action.....cheers from Florida, Paul

[@christianzuniga9000]

either the welders are short or the miller guy is tall asfffff

[@BRICEN18]

That induction heater would be ideal for pulling and installing interface fit couplings!! If it would get hot enough.

[@craigbowman4830]

We use machines up to 200kW for this application. We are talking about serious shrink-fit components (blower hubs, retaining rings, bear races) etc on industrial turbine generator rotors, roller mill motors, etc. It gets plenty hot. With the machine in the demo (Proheat 35) I have heat a 14,000lb steam chest to 1200F. We also patented 'bolt heating' technology using induction some 25 years ago. The largest we've heated with this technology are studs with through-bores up to 18".

Shit is right in the way I'll take the old style heat treat

[@benwill5426]

I just don’t see this being stronger than tig welding the root. Ive worked in many power plants and you won’t see this in the field. They also make a flux coated tig wire to circumvent purging and it runs pretty good.

[@christopherblanda9502]

You will 100% see this in the field bud 🤣 and don’t lie that mud rod runs like trash and u know it rmd is literally quicker and provides a more consistent band and easier flow within the pipe not to mention it’s a hell of a lot quicker not saying it’ll replace tig but it’s definitely going to be seen a lot more then it already is. Just gotta keep up with the times son

[@MegaBlackman321]

Been using this 2 years in the field building 2 power plants. I don’t see it replacing tig but it does come in handy when you’re welding 24” 9chrome 2” wall. Guys are knocking that shit out in 8-9 hours here. It’s all about production

[@projectgz]

Dont need to be more stronger , just more fast and strong enough , time is money

[@mikereimer4048]

Won't see this in the field? That's almost all we use on pipelines 20" and up now.

[@benwill5426]

@@mikereimer4048 you use copper nickel on the pipeline?

[@promobass77]

by the sound of welding, I will say that the current and feed parameters are not properly selected.

[@mikereimer4048]

That's what RMD sounds like.

[@kirstenspencer3630]

Yes, normal RMD sound.

Is that a 75/25 mix

Can I get a hell yea!!! 😮‍💨🔥🔥🔥 nice work gentleman!

[@gto9485]

I'm new to welding but I don't know how to configure the welding machine in 2g because the rod doesn't turn on but if I put it on the table it does turn on

[@giannifabbroni6442]

Porque no explican que tipo de hilo usan, si es básico, hilo animado y sí sé usa gas para soldar

do a 9% chrome with the tig and show more of the root .. thanks

This is a simple version of heat stress. I did this for 3 years

[@brandongonzales6887]

@Leonardo Morand This is heat treating. It is induction. Same principal as resistance and gas heat treating. The term for this particular application would be Pre-heating. Being 9% chrome and having such a high interpass temp I’m sure it would be followed by a slow cool.

[@nardo34480]

@@brandongonzales6887 where can I find jobs to do this? What is the name for when you bond them after they weld? I'm looking for those jobs

[@brandongonzales6887]

@@nardo34480 well that depends on where you’re located? I’m right on the gulf coast and we have quite a few heat treating companies around here. Analytic Stress, Texas Stress, ITS, SuperHeat, and also a lot of your Non Destructive Testing companies will have a heat treating side to them. And if you’re talking about the process after the weld is completed then that is Post Weld Heat Treating. I’ve never met anyone who knows the exact scientific process that goes on during the heat treating but it has to do with the molecules in the material. Realignment I’m assuming. I started welding so I have not been looking for a heat treating job so I don’t keep in touch with anyone from my past heat treating jobs.

@@brandongonzales6887 I'm a welder but I was in Pennsylvania at the monaca cracker plant and I was doing post weld heat stress for 3 years. They pay good but i was sent there as a welder but ended up doing that. Thank you for naming some jobs as well im going to look for them now that I have a proper name cause i actually enjoyed it and it wasn't really physically demanding.

[@bartroberts1514]

Really interesting. I've been looking for a technology to use with concrete pours of pozzolans that benefit from curing for 28 hours at 130 F. Could this welding induction heating system be adapted economically to such uses? Geopolymer pozzolan can get up to double the strength with precise temperature, and cure in a tenth the time of conventional OPCs.

[@Whereismy10mm]

Induction heating only works with ferro metallic materials because it uses magnetic induction to produce heat.

[@bartroberts1514]

@@Whereismy10mm Absolutely true. And not a problem where steel rebar or staples are used in the structure or aggregate. More like an opportunity. The questions I have are how much ferromagnetic material is needed, how deeply does the induction heating penetrate, how practical is it to use this equipment on pours, and how cost effective? Thanks, and looking forward to more discussion.

[@Whereismy10mm]

@@bartroberts1514 it would not work well in the that application. First of all you would only heat those Ferro materials, so you wouldn't exactly have consistent heating throughout the concrete unless it is evenly spaced throughout every cubic inch of concrete. Secondly, the inductive heater needs to encompass the metal. So unless you can wrap the coil the entire way around the concrete you are trying to heat via the metal, it wouldn't be feasible.

[@ShainAndrews]

LOL. Nope. I know how you can do it... You can't afford it.

@@ShainAndrews Huh. Way to rez a zombie thread.. six months after I found the solution I wanted.

can you just weld it cold and get the same result?

Chrome has to be preheated.

Just like cast iron needs to be preheated. Using cast iron rod.

A post heat as well .

[@creeplife2802]

"Chrome"? What!? I thought it was just a plating

[@Whereismy10mm]

When plating, you are adhering one metal type to the surface of another metal type. Therefore yes chrome is a workable metal in its own form.

[@Whereismy10mm]

Look up electroplating.

[@wayupinya.]

Wouldn’t it be heated way over 400 degrees when you start welding lmao

[@mikereimer4048]

Yes. But 400 is minimum preheat. There's always a max heat too. On the steam pipelines we build, minimum is 300 and maximum is 500.
