Man good job. I’ve done a ton of repairs over the years and am one to always try to reuse, save, fix, repair. Whatever. But man. She was almost to far gone. Good job bringing her back. Whoever is running that machine shouldn’t be aloud to. There just not using it right to break it that many times.
Operators always get blamed for breakdowns. maybe the wrong machine was used due To boss's hurry. you don't know the whole story. U sound like a know it all.

I'm not a digger driver, but to me it looks like some those cracks were caused by sideways or twisting forces on the boom. As if the driver was in the habit of putting sideways forces on the bucket instead of pulling/pushing. Good repair, wonder how long it'll take him to wreck it again!
Yes , its called " Sweeping " , and usually it causes cracks up at the arch of the boom , twisting against the inside baffle plates , or around the lift clylinder furrels . Im the shop foreman , Mr Meany . You sweep our machines , you sweep out house for 2 weeks
any video that will hold my attention to watch every second of it is more than worthy of a sub. You certainly made the person who repaired it the last time look a little amateurish. Thank you for sharing your world with me/us.
I was a fabricator/welder etc etc for Halliburton. Some of the "field" repairs stuff was off the chart likethis boom repair. Some pieces were so thick it took two rosebuds to preheat. It's was hard work many times but I loved it.
That is a real nice repair considering what you started with,and should outlast the rest of the machine. The guy that did it before tried for his ability and what he had by the looks of it. it's amazing how much worse stuff i see here in Canada on farms where they just wasted 3 packs of rods and found some old flame hacked scrap to weld on that wasn't even suitable for the repair, welding to me is something where less done right can be better with some jobs. One loader I saw looked real rough and the guy told me the "local welding shop "did it. I'm not a full time professional welder by any means and generally don't do much customer welding, unless it's a smaller repair or I know it's within my ability to get it right. if that was my machine it would of never left my workshop looking like his did, and I'd certainly never billed a guy for the mess either. They go big on licences not practical experience for most trades here. I got my UK city and guilds in Ag machinery nearly 30 years ago, half these guys here i'd run away if they start saying i've got a licence for my trade. It's pure garbage they put out and bill customers for if you understand quality workmanship when you are educated, and know if they did it right or not for the huge price they charge an hour for the age it takes them sometimes. Thanks for the video, Take care.
Your comment reminds me of something similar here in the USA, though my example is on a much smaller scale. I'm strictly a hobby welder but I can mention that I was pressed into service at my place of work to repair the boom of a truck-mounted drill rig where the connection for one of two hydraulic cylinders for lifting that boom had ripped completely loose. It took me a few days of piecemeal work, shopping for materials, fabricating patches at home and bringing them back for fitting and welding at my place of work (a pro with all the right equipment could have done the whole job in a couple of hours), but now ten years later the repair is still holding up. Years before that I took an introductory welding class at a local technical college to get a jump start on what I might otherwise only have learned after years of practice or maybe never at all while trying to figure things out on my own. The class was mostly made up of local union plumbers who where there to get "certified" that they could do the kind of welding that might be required at times in their line of work. All those guys were total clutzes who's arc and puddle control wouldn't have been any worse if they had been welding with their feet instead of with their hands. There were two classes a week for six weeks, and during that time these guys just never got any better at all, I think because they couldn't be bothered with thinking or *caring* about why they were there, and yet they came out of there with their union certifications that they had been "trained".
Yes shit on the guys that have tried to have a go. Fantastic you have 30 more years experience than the rest. You started somewhere, and didn't know it all. And if all the customer wanted was a quick fix to get them through which was cheap then they got that. I hope you don't fall off that high horse you're on, or you'd better have a parachute.
@@ToxicMrSmith YUP my first reaction was like yours (a bit milder) but then consider his PRIDE in his hard won SKILLS I agree, being a fan of ag videos that Sven the farmer needs to spend a week at a welding basics course So MrSuper why not make a must see video of welding basics for those SOD (and equipment) BUSTERS !!

I have been doing this exact same type of work for the past 16 years. It takes a massive amount of prep to do a good job. Patience is so key and not to rush to weld. Been watching your videos lately and can't say enough about how good of a job you do. Its been several years since I had a partner in the shop that worked efficiently and effectively. Lol I would take a $10 hr pay cut to come work with you!
Absolutely fantastic! This is the proper way of doing a repair correctly. Don't scab on more crap like it was when it came in for repair. Remove ALL of the bad work and start fresh at the base metal! Great job!! This repair will last the life of the machine. 👍💪
Okay, I'm no pro, but that looked like awesome quality of work that you were able to keep those pin holes lined up so well. I can just imagine that pin getting more and more stuck due to warpage as work progressed, but you avoided that problem.
It is nice to see someone that really knows what they are doing. I am curious as to how costly would a repair like that be? One heck of a lot of work went into that job!
I like the repairs you have done on the plant machines. And all the scrap balers and quarry crushers real heavy duty stuff. And a lot of hard graft and sweat. I was very interested when your uncle drew said about his patent. It seems to me that clever people like him with good ideas and designs get taken by other people who could not work it out themselves. He was right in my book. Knows his stuff for sure. I am a big county fan love your fathers tractors and enthusiasm. Keep the video's coming love em best wishes to you all at Cooke engineering. From jonsey south Wales GB.
I watch your videos and think I could fix it just as good with my mig and a grinding disk and some plain square patch plates. My repair would be half as good as the repair you just untangled that wasn’t nearly good enough. You are really good at what you do.
I used to love using the gouge cutter. And fixing someone elses bad work too. I miss welding for a living . I still do it on the side but it`s not the same as industrial fabricating. Cheers from Ontario ,Canada.
You can tell the quality of the work you will get by the gear the welder wears! A true pro takes his own care first and then the job! You should teach, you make it so clear!
I haven’t commented before but this repair was a thing of beauty. I would like to know more on what products you use and why and also your techniques using them.
That was a fish plated hunk o junk. This repair was a better repair than that just get it back in the field messy attempt at a repair. I have done many Cat Excavator boom repairs. Most manufacturers have a written procedure for boom repairs but the problem is companies don't want to spend the time to do it right. I was wondering how long it would take him to move that cylinder out of the carbon arc blow. And damn, move the hard lines. Good video though.
I'm no welder but sometimes customers don't want to pay to do it correctly. I was an auto bodyman and I had to do that just to stay in business. I always made them sign off before I started the repair.
So here I am going through the tube vids looking for help and information, with a view to buying my first mig welder. The information so far indicates that 'gasless/flux cored' machines are for occasional light duty diy use only. And then I stumble upon your videos. And you are rebuilding monster machines, and smashing in two inch plate with 1.2 mm flux core! And I am mind blown. I appreciate that your welder will be oodles of amps and your wire feed rate no longer measured in metres per minute, but spool RPMs. But I'm still well impressed.
I work for a company that manufacturers explosive vehicles for mining companys the amount of times I've had to do similar things to AN bins and Emulsion tanks is ridiculous. Comment of the century for the grinding over head mate.
Your skills appear to be near perfection. I know very little about welding; however, from a physics aspect, the curved edges provide more strength than right angles and straight edges. I am glad you are keeping the workers safe by utilizing your strengths! and skills!!
Great video and great work. Do you think if this machine came from the manufacturer with the reinforcement you installed, the boom would ever need repaired ? Just wondering why they aren't reinforced from the factory.
Another well done and very elaborate repair. I recall some repair welds are on both sides of the plates. Are you able to apply the root passes without any backup strips to avoid any internal notches? It seemed like the previous repair came undone from the inside out, so just wanted to know your strategy on how to prevent this.
I love how the patch on the patch welds were ran downhand. When making a repair weld weld uphill in stringer beads, not big weaves. Also grind or gouge a V in the crack to the base of the crack so you have 100% penetration. A good weld the weld will be stronger than the base metal. These patches were not welded with structural welding rods or wire.
@@grahamshelton3448 I’ve been welding since ‘89. That is the welding process for repairs, especially if it’s going to be inspected. UT or X-Ray. Sorry if it’s too much information for you.
gary24752 You can't weld straight against the grain of the stick as it will crack right across it. The shapes will prevent it from cracking at the weld.
FANTASTIC JOB. THE FOLKS THAT JUST WELDED UP THE CRACKS DIDN'T CARE ABOUT QUALITY... IMO. YOU SIR ARE A CRAFTSMAN... YOU DID EXACTLY WHAT IS SUPPOSED TOO BE DONE TOO REPAIR THAT DIGGER.
Very interesting video, thanks. I can see that the plates you added are shaped to minimise stress but some explanation of how this works would be most welcome. Your videos are most enjoyable.
Do the manufacturers ever take note of fails like this so as to improve and / or operator-proof their designs ? Perhaps building to a price (and short warranty periods…) makes this irrelevant, but you would think that Cat, Deere, Volvo et al. would correct inherent design flaws based on field work. This one seems properly knackered !
Great to see some-one who knows what they are doing.........except the over-head grinding...this is where a 2nd year apprentice would fit the bill...Shudder when me sees carbon arc gouging in a workshop......from a previous pressure vessel welder and later a welding inspector...from Australia..
Good job man that's the way you fix it I seen so many of them they just weld in the Skin's back together or replace badly fractured pieces with new the only one that I seen doublers on is this one when your back feeling with the bucket it creates a lot of pressure on that knuckle and doeblers are the only solution
good job when filling the gaps do you let the weld pool grow and then move on as it touches the sides? what sort of amps are you using? thanks for sharing
Hello. I have enjoyed your repair video a great deal. I am not a welder like alot of your other commenters. But how about a video on what equipment your are using and a bit more detail on the wire type etc used. Keep up the great production and the great work.
@@allistairc123 .. How much cheaper is it for the machine to be down 5 or 10 times not to mention people like you fixing it? Most importantly hopefully nobody getting seriously injured or worse killed. Old saying pennywise and pound foolish. It's not your fault I blame the owner.
How did you keep the 'flux core BB's" away? Your weld looks almost clean of them and I don't see the telltale grind spots showing where they were. Excellent job. What were the drill holes in the fish plates for? Allthread clamps?
First repair(s) - likely the owner/operator just bodging it together to keep going. Until it got so bad he finally calls in a pro. Always wonder why they bother trying to fix these old booms - by the time you add up the cost to repair multiple times and the downtime on the machines, just go buy a boom off a scapped machine and save the headaches.
ArthurDentZaphodBeeb not too many of these 30 year old machines around as donors. It's worked all its life in a quarry, even if it doesn't quite make 30 more years still worth 3 or 4 days, even at premium rate!
ArthurDentZaphodBeeb I bow to your knowledge, perhaps you should go to Ulster and set up an agency? Although finding, buying, and fitting one may make 3 days labour and some plates seem like a good deal.
Why didnt you strip the side plates right down to the end , and take in the end of the stick eye , then you could have eliminated the veed butt weld in the high- torque area ? I machine new stick eye furrels , and wrap the center the same way ,but make new ears as well . Most of the ones I get , didnt break , the hole wore out .
Do you disconnect the batteries when you are welding, something people do, others don't. I think it's a good idea, alternators and e.c.u.s are sensitive to power surges.
Overhead grinding should be reserved for the person who “repaired” it before. You did it right. Outstanding job.

@@treavormiller9552 just wanted to write exactly the same.
Have watched some other repair video's and you are the only one to preheat before welding. Glad to see it done right.
I thought preheat was only needed for high strength or high carbon steel. Is that what’s used in the boom!

I love how the patch on the patch welds were ran downhand. When making a repair weld weld uphill in stringer beads, not big weaves.
Also grind or gouge a V in the crack to the base of the crack so you have 100% penetration. A good weld the weld will be stronger than the base metal. These patches were not welded with structural welding rods or wire.
Go away
@@grahamshelton3448 I’ve been welding since ‘89. That is the welding process for repairs, especially if it’s going to be inspected. UT or X-Ray. Sorry if it’s too much information for you.
Shit, sorry. Misread what you wrote. But honestly, go away
@@grahamshelton3448 😂
Cracking job was a pure pleasure to watch you fix someone else's temp repair
Nice finish
👍👍👍😜🏴🦄🎣😁🤞✌️
Well done! Keep up the good work! That flux core is nice to work with. I have it in my Miller 12VS. Great stuff!
Home run! Fantastic, exceptional. Lots of skill.
What is the theory behind the shapes of the patch plates? Great looking welding.

You can't weld straight against the grain of the stick as it will crack right across it. The shapes will prevent it from cracking at the weld.
FANTASTIC JOB. THE FOLKS THAT JUST WELDED UP THE CRACKS DIDN'T CARE ABOUT QUALITY... IMO. YOU SIR ARE A CRAFTSMAN... YOU DID EXACTLY WHAT IS SUPPOSED TOO BE DONE TOO REPAIR THAT DIGGER.
Loving the content mate. It would be nice to know estimated cost of repair on some of these jobs. Awesome skills.👍👍👍👍
Very interesting video, thanks. I can see that the plates you added are shaped to minimise stress but some explanation of how this works would be most welcome. Your videos are most enjoyable.
For military we preheat to 250 degrees and post heat. This avoids cracks..... the only way, he's the first guy I've seen preheat as well.
This chap and IC weld I rate very highly . Highly skilled people .
Love to see work like this, done in the right way.
Just subscribed 👍🏻
You amaze me. Great job! This job was amazing!
Great repair, but please dump the annoying 'music'! Turned the volume off for most of it.
brilliant job, working on those big machines is hard work, well done, proper job,
It is shocking what some people scab together. It sure makes the next repair a CHALLENGE!!!! Keeps you employed!!!! LOL
fantastic video, great to see inside the boom. was expecting a web inside the boom like an H section beam.
If I did a repair job like that shown in the beginning, my welding instructors would hunt me down and make me do it right!
Very thorough repair. No shortcuts. Good on you!
Do the manufacturers ever take note of fails like this so as to improve and / or operator-proof their designs ? Perhaps building to a price (and short warranty periods…) makes this irrelevant, but you would think that Cat, Deere, Volvo et al. would correct inherent design flaws based on field work. This one seems properly knackered !
Great to see some-one who knows what they are doing.........except the over-head grinding...this is where a 2nd year apprentice would fit the bill...Shudder when me sees carbon arc gouging in a workshop......from a previous pressure vessel welder and later a welding inspector...from Australia..
Nice job, bud. Truly looks better than factory! Overhead grinding comment was mint also!
You do very nice work !!!!! You treat each project as your own equipment or item. Cheers...
They should have called you first. Poor machine.
Good job man that's the way you fix it I seen so many of them they just weld in the Skin's back together or replace badly fractured pieces with new the only one that I seen doublers on is this one when your back feeling with the bucket it creates a lot of pressure on that knuckle and doeblers are the only solution
That’s a proper repair bud nice work!!!
I'm not a pro welder bud the previous welds look awfully! Great video again.
Keep it up!
good job when filling the gaps do you let the weld pool grow and then move on as it touches the sides? what sort of amps are you using? thanks for sharing
Great job there. What brand/spec of shielded flux core wire do you use for those type of repairs?
very nice ...what type of wire and steel did you use for the repair??
Hello.
I have enjoyed your repair video a great deal. I am not a welder like alot of your other commenters. But how about a video on what equipment your are using and a bit more detail on the wire type etc used. Keep up the great production and the great work.
It just like going to the dentist. He has to remove your cavities and fill them back in. Nice work fella! 🦷⚡
Massive repair! What’s the advantage of the flux core in this situation? I would have thought the extra cleaning time would have been an issue?
Здравствуйте.Отличная работа. Не понятно, чем срезали старые усилители?
Very Nice Work
A very talented fabricator and repairman. Enough said!!!!
It's like super gluing a broken China plate and using it in a frisbee competition. The whole section need to be replaced that's scabbed together.
You couldn't do it on the budget...
@@allistairc123 .. How much cheaper is it for the machine to be down 5 or 10 times not to mention people like you fixing it? Most importantly hopefully nobody getting seriously injured or worse killed. Old saying pennywise and pound foolish. It's not your fault I blame the owner.
wow! that's some serious welding right there. Did you have a pint of Guinness after that?
How did you keep the 'flux core BB's" away? Your weld looks almost clean of them and I don't see the telltale grind spots showing where they were. Excellent job. What were the drill holes in the fish plates for? Allthread clamps?
If the first repair would have been done like this repair it would have been the last repair. That is impressive work.
First repair(s) - likely the owner/operator just bodging it together to keep going. Until it got so bad he finally calls in a pro. Always wonder why they bother trying to fix these old booms - by the time you add up the cost to repair multiple times and the downtime on the machines, just go buy a boom off a scapped machine and save the headaches.
ArthurDentZaphodBeeb not too many of these 30 year old machines around as donors. It's worked all its life in a quarry, even if it doesn't quite make 30 more years still worth 3 or 4 days, even at premium rate!
@@industry65 there are thousands of old machines sitting around contractor yards, farmers fields and outfits that part them out.
ArthurDentZaphodBeeb I bow to your knowledge, perhaps you should go to Ulster and set up an agency? Although finding, buying, and fitting one may make 3 days labour and some plates seem like a good deal.
Why didnt you strip the side plates right down to the end , and take in the end of the stick eye , then you could have eliminated the veed butt weld in the high- torque area ? I machine new stick eye furrels , and wrap the center the same way ,but make new ears as well . Most of the ones I get , didnt break , the hole wore out .
Hi! I really enjoy watching those big machines coming back to life. May I ask - is it normal that those repairs aren't painted afterwards?
Depends on customer preference
@@allistairc123 thank you 🙂 I just think such a good job begs for painting 😁
Great work.
PD: Previous welders must be seeked, identified, and finally put away of any welding machine for 10 years.
Hi ... Possible to list down the tools u used ?
Do you disconnect the batteries when you are welding, something people do, others don't. I think it's a good idea, alternators and e.c.u.s are sensitive to power surges.
Cracking job it’s just unfortunate your having to put a bad repair right, if your going to do it you might as well do it right 🤷♂️👍👌
