  • The seal surface of this crank pulley is badly worn and we’re going to repair it with metal spray! This crank pulley is off a Caterpillar 3306 Engine from a CAT 637G Scraper tractor and the seal surface has a deep groove worn into it that needs repair. We show the step by step process of metal spray welding using our Castolin Eutectic Rototec setup. First we prep the part by machining down the worn surface and apply the masking compound. Then we use our metal spray gun to pre heat the part before spray welding on the new material. Once the part has cooled we machine it down before finishing it to spec using emery cloth.
    In this video we are using:
    - Hafco TM-1740G Centre Lathe
    - Castolin Eutectic Rototec spray gun

    I'm a machinist for a large CAT dealer here in the US and we flame spray almost every single part that comes in for repair. It's cool seeing someone with a large viewership doing the same thing. I would like to point out some things I do differently you can try out for next time. There is no real advantage to putting a thread into the under cut area. I've found that just running a fast feed rate like ~0.015"/rev while undercutting provides a very consistent but still textured surface for uniform adhesion of the spray. With a part like that with a 4" OD I'd run at around 150rpm with 0.006" feed rate when turning back to size with ceramic insert, it sounds slow but that spray is almost like sandpaper and turning too fast will literally melt your carbide cutter, like what happened to you. A seal area like that probably has a +-0.002" tolerance from CAT so I turn it to the top end of spec and then lightly polish with 240 grit paper. Going with a finer grit just exposes graininess in the spray.

      @basketofdeplorables4253 most steel sleeves used to repair CAT components are from mild steel, rhe exact material is dependent on recommendations in the cat literature but unless it's a very specific use case it's not going to be wear or abrasion resistant. In fact, we actually use more cast iron sleeves to repair wear components than we do steel.

    Eutectic metallurgy is really quite magical. Essentially the powder and the steel form an alloy right where they meet, and the melting point of that alloy is much lower than either metal alone, so it's a cold process (as opposed to welding, where you must melt each metal separately). The warm powder and warm steel form an alloy on contact, forming a strong tough bond. Magic!

    I was a machinist at an aircraft manufacturer. I didn't have any weld experience except for what I saw taking place at times. One time I needed to have an aluminum engine component welded but the welder told me he wouldn't be able to weld it until it was degreased. I took it the department that had a degreasing vat - it was a heated pit that had a chemical degreaser in a vapor state. The aluminum part would heat up - i suppose to a couple of hundred degrees- while the vapor remove the old oil from the metal pores. At least this is the way I understood the method to be. Nice and clean afterwards- the welder and I were happy.
    Just a memory that came to mind.

Having watched Adam metal spray for years I was delighted to see that the process also works in the southern hemisphere! 🙂 One of the first things I learned when I was in engineering school was that all machining is "subtractive manufacturing" and basically, until 3-D printing came along metal spraying was one of the very few examples of "additive manufacturing." Being able to do it right in the lathe where you will be turning it down is a real advantage, too. Thanks for letting us watch, and Karen, thanks as always for your stunning videography!

Your detailed step-by-step guide to metal spray welding using the Castolin Eutectic Rototec setup was incredibly informative. Starting with the prep work like machining down the worn area and applying the masking compound, followed by the metal spray gun pre-heating - it's obvious you know your stuff. And then, watching the part cool down and machining it again to specifications using emery cloth was a great way to show your dedication to precision.

    I went through some seal training with SKF a few years ago.

As the surface gets bathed in oil the rotation of the part can pump oil. Love the content Kurtis and Karen!
