Line boring and bore welding rototilt attachment

In this video i line bore and bore weld a worn hole on a rototilt attachment.
The grease pipe had got damaged without realising meaning the brush wasn't getting any grease.
First the hole was line bored back round again and oversized. The bore welder was then installed and set up ready to weld, problems with the gas coverage meant the weld was bubbling and very badly porous. After 2 failed attempts and having to bore the weld back out again, i realised the problem was with the shroud. With a longer tip and a better shroud the bore welder finally performed like it was supposed to.
2 runs of weld were built back up in the hole before line boring back to 70mm
The new bushes were then pressed in.
Hope you enjoyed the video.
Thanks for watching!

Amazing how quickly 43 minutes flew past. You did not have mistakes you had a problem to solve and you brought us along as you solved it. Very educational.

[@hansbjaeke3414]

Very nice job an a very good video again. Showing your mistakes is very important and makes your videos so natural, feeling close to the real world jobs where nothing goes right first time. Doing it by hand would certainly have been faster, but now you learned about this process and have a new tool in your sleeve for future jobs. What i particularly liked about this video is your camera work and exposure settings (not too dark or too bright) around the bore welding showing the process perfectly. Thanks for your great work! 😊

Happy New Year, Oliver. I wish you all the best, mate, for 2024. There's always the chance from oil or grease contamination when lineboring, which can cause unwanted bubbles as you had and is not just poor gas flow. A guy I used to watch in California sadly died in 2021 from COVID. He worked with heavy plant machinery, the really big stuff, earth movers, scrapers etc. He would pride himself on making sure he did the best possible job that he could because, in his line of work, reputation meant everything. He learnt the hard way, just like you will. So, whenever he had a job where brass bushings were greased via nipples or greasing lines, much like the broken one on your project, he would use a blow torch with the biggest rose tip I have ever seen. He would heat the work up prior to welding, which, as you know, causes grease to leak from joints that were invisible to the naked eye at least, on camera they were. As a fabricator welder, I know only to well the issues with poor welds when rust, oil, or grease are present. Either one can be the difference between a good or disastrous weld and the difference of being contracted to do more work. As for the shroud, we never had the fancy pancy ones you have. All we had was the standard type like the ones you use with your mig welder. Try using that one next time, of course, you will need to make adjustments but checkout the difference. Lastly, edit your videos of course but always show your mistakes. That's how everyone learns. Thanks fella, looking forward to seeing your next project. 🤘🇬🇧⚒️

How refreshing to see a really hard working and very skilled tradesman working in a rough shop and turning out first-class work on busted equipment that most shops would refuse--at least that's how it is here in the U.S. Great work, humble and honest attitude, and no infomercials!!

Nicely done, at least you sorted out what was wrong with the gas shield. I know once we were on site and getting similar bubble welds and it was down to a strong draft, once we shielded the work area it was fine. When you first put the legs on the rotor it looked like a demented robot, I did chuckle. Stay safe and well mate 👍

[@warrenjones744]

I have had many things go wrong with bore welding, but the bore acting like a chimney and sucking the gas away is not one of them. Clogged holes in the diffuser, inadvertently not having enough flow or no flow of gas. (running out or pinched gas line) Bad bottle of gas once. Too much gas flow causing turbulence or just plane crappy material are a few of the adventures. Once I was involved in testing some ideas for a stubby compact torch and we found that the diffuser was not long enough and had to add a baffle plate inside the works to allow it to work. That idea went onto production and is still in use. Looks like you encountered a similar problem with your short shroud as you call it. Looks like you got it sorted out out, well done Oliver Cheers. Edit :sometimes in multi pass welds you need to do some touch up by hand It's nothing unusual.

[@kevinsantema6807]

Well done, l like to use a chain ratchet on the forks for lifting, then I can easily adjust what I’m working on without having to go back to forklift all the time, thanks for the real life videos

[@bostedtap8399]

That was a tough nut to rack, brilliant diagnosis on the short shroud issue, guessing the shielding gas was uncontrolled, with no lamellar flow provided by longer, narrower shrouds. Obviously bore diameter dictates shroud length. Very interesting Oliver, thanks for sharing 👍. Best regards from the Black Country. John.

[@andywindy]

The only way to learn is to do, work out why it didn't do what you wanted, and try again and again until you get the results that you wanted in the first place. We appreciate your honesty in showing us the struggle, thank you.

[@davidsnyder2000]

What a great job diagnosing the gas coverage issue with the welder. I wouldn’t have figured that out on my own. I was definitely thinking the metal itself had contaminates in it causing the bubbles in the welds. You definitely taught me something here👍

[@Snipersteve18]

I would suggest getting a set in bore snap gauges for measuring your internal diameter. In my 6 years Lineboring experience I’ve found that get a hot preheat then letting it cool a bit to burn any grease or impurities out does wonders. Also if your bore welder has the ability to adjust the step up function, if you run a very small step for the first few rounds it will build up the bottom eliminating the need to hand weld the bottom.

If your a plant engineer you will come across stuff like this weekly look at how bad most of these attachments are abused (30yrs in mines/quarries) the more you use the bore welder the better you will get, they do chimney more in cold weather and it is cold up your way, sound job Oliver.

You really could do with making overhead gantry spanning your shop as you've got the skills and bet you could do it your sleep as always great to watch you videos keep them coming .

[@glenn81989]

The main problem in the middle of the video is grease at this point. It killed you the nozzle and afterwards you hat problem with gas coverage and dirty material. Sometimes you shoot completely yourself with that, if the welded material becomes hardened by the grease. I also paid a lot of time with such issues. For my experice it is the best to take a small grinding disc in advance and cut in a groove in this attached tube and hand weld it out before you bore weld. I was several times in the situation that it looked clean and i thought i dont need preparation. I always failed in the first try ;-)

[@glenn81989]

It is also my experience that the choice of the gas nozzle is very critical. I do it like you and grind my own nozzles. Perfect bore welding is not that easy as it looks like :) and it becomes Mode and Mode difficult with smaller holes.

Happy new year young man . Well I gotta say you definitely deserve praise on the bore welder fault finding and reboring of the hole more than once .. was a great bit of fore sight on the mounting point being suited to both the welder and line borer. And credit for leaving in the issues . Thanks for a very interesting video for the start of the year .

[@Malmgren828]

A good starting position for setting the correct gas flow is 1 liter per mm diameter of the gas cap, too high a flow can create turbulence that draws oxygen into the melt. From what I can see on the video, your problem with pores may be grease creeping out between the thicker plate and the welded on ring, it may be good to preheat to "burn" the grease before welding.

[@snowballengineering]

I did preheat it on the second attempt and still had the same problem. I think the old shroud was too short to effectively spread the gas out over the weld.

[@Malmgren828]

@@snowballengineering Ok preheating check. Now it was fine when you changed the gas cap, so the problem was solved, but it feels like it should have worked with the first gas cap as well. Nice work 👍👍👍👍👍

[@bigalhudson]

Great video. Interesting how you solved the weld porosity problem. Seems odd that even when you turned up your shielding gas to maximum it didn’t solve the problem? Am I right that the welding tip had also been ground bacK/modified? Maybe the tip was the problem and not the shroud ? Anyway learning a lot from you.. thank you. Happy new year
