9% Chrome RMD Welding | Heat Induction 

🤙🤙

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".

That's what RMD sounds like.

Yes, normal RMD sound.

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

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

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

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

@@mikereimer4048 you use copper nickel on the pipeline?

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

@@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.

@@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.

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.

@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.

@@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

@@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. I Eben ran cable tray and installed data and power cable there as well...

@@brandongonzales6887 I'm in Florida by the way

Tejus... never sends their best.

Chrome has to be preheated.

@@weldtube ah yep okay

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

@@RBFR01 it will crack.

A post heat as well .

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.

Look up electroplating.

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.
