The weld looks nice, but it will just crack again after a while. The area immediately around the weld has been severely heat affected making it prone to developing further fractures. If the job is to be done correctly, a stretcher plate should be placed over the repair and welded in carefully. The stretcher plate should also not terminate in a right angle across the boom, instead it should be diamond or V shaped as to avoid creating stress points that might also create possible fractures.
Stop drill the end of the crack with a drill bit. 3/32 or appropriate size this will stress relieve the crack. Then do your welding. Something I learned in aircraft school. Where to start weld I don't know.
@@michaelwesely3097 That's the problem, on something like this there's really no easy way to know how far the crack has propagated if you don't have access to x-ray, or at the very least a dye penetrant test kit. It could well extend most of the way across the boom, which is also another reason to plate over the top of the original material.
Agree, now that he's repaired that.. It's now ready for about 30" to 36" long reinforcing plates, on top and sides, preferably matching existing thickness. The repair should always be stronger than the original.
First, here's some tips given to me by a Caterpillar tech. You have to cut a larger section out, make sure and clean everything (these machines are always caked in grease in my experience) and cut bevels into each edge. After you weld in the new plate (no beads wider than 2x the width of your rod and only 7018 or 8018) clean it flat and put what we call a fish plate on top. Cut a square a few inches larger than your repair, and 45* the edges off about 2 inches in on each corner. Weld up the long sides, and don't weld the 45* edges. When you start and finish one of the long edges, make a little curl....don't start/end the actual weld on the part. Start about an inch away from the plate with the little curl, then tie into the fish plate. After learning this, I've never had a boom come back for the same repair.
This seems to be a very professional advice. You actually mentioned the type of welding rod, the scub or fish plate and it makes sense to me that there will be 45 degrees corners on the fish plates to avoid stress concentrations that will be prone to new cracks formation. Great job. It's painful to see an uneducated mechanic produce a nice looking "repair" that will crack again in the near future
Foolish. Another clown saying to plate a boom. Booms flex, plates make it rigid. I seen countless boom crack worse due to plates. Never smart but then again you're just some cat employee wage sІаve
As a retired welder, machinist and fabricator, there are 1000 ways to repair the boom. Your way was 1 of them, but it's 850 choices down from being the best choice. Aside from the fact you weren't using enough heat, you should have been using a heavier rod just for starters. And guess what, the boom is going to crack again, but at least twice the size. You don't understand metal fatigue or welding. Quit making videos and go to school or serve an apprenticeship.
I don't see the point of cutting a wide notch just to scab a little chunk inside. You need to think of the whole boom as a dynamic elastic noodle. Now it's got a stiff spot in the middle of an elastic beam. It's going to crack again. You need to add fishplate reinforcement with long feathered slopes to allow elastic bending to occur over a metre of length.
You hit it on the head man. As an Ironworker your only aloud to go a pass or two thicker than the steel your welding because of what you just explained. He’s causing a two points of weakness with that repair
I worked at a sawmill that used 6 excavators with grapples to sort logs in the yard. There was one operator that was constantly breaking machines. Very rough on them. Summer months were already 18 hour days trying to keep up with rolling stock maintenance, then have that one guy causing all kinds of extra work. The worst was the house bearing cracks that ran almost the entire circumference underneath in the well. It had probably over 100 pounds of old grease that pushes out that had to be scooped out into buckets, then steam pressure washed which was absolutely miserable. That hot steam mixed with nasty grease swirled around and plastered your neck. Only after it was cleaned could you see how bad it was. The excavator was very near breaking off and falling off. That replacement bearing 25 years ago was over $50,000 too.
For real. Your eyes are so soft and fragile and even a tiny eyelash you'd never notice otherwise can bring everything you're doing to a screeching halt. A single grain of sand can do pretty incredible damage to your eye if it gets in there and you move your eye around and it scratches the surface of your eye up. I can't fathom a piece of metal getting in my eye. What an appalling thought.
Might Crack again, will Crack again. Some say too much heat in the area but that is solved by plating the weld areas with same plate and a 3 plass fillet
Very nice work!…. I agree with everyone else, weld is strong but you should weld on Diamond or V shape reinforcement to strengthen the stress on that break! 👍
@@skorpio1905 I can promise you, unless you can somehow grind it perfectly flat, and get new paint to match the rest of the boom, it will be obvious that it's been repaired.
I'm no welder but I think an extra plate to cover the weld area and beyond would be a good reinforcement. Unless they want more work in a Month's time.
Canadian boilermaker here. I agree with you completely! This whole job is dogshit!!! All the people that know nothing about welding calling this good are hilarious 😂 loll
Доброго времени суток...у меня есть один вопрос...почему вы не делаете накладок и как долго работает стрела после такого ремонта? Не идут ли трещины в около шовной зоне? Больше спасибо за ответ)
Она ходила бы гораздо больше, если бы он не стал заправлять полностью этот вставыш, а так представь(я думаю сам понимаешь) там сейчас перекаленый в хлам кусок металла в напряжении, его по хорошему можно машкой и зубилом вынести сейчас, остановись он на коренном шве, было бы куда надёжнее, и то в случае, когда нет возможности сделать качественно и по уму
Nice simple neat repair, I know it takes the neatness away a little but when I’ve done them in the past I’ve repaired like you but then added a larger plate over it at least 100mm past each side of original split and I know it’s lasted 4 years so far 👍🏼
Top plate is a great advice. Filling that hole makes no sense at all. That's just cosmetic. Adding a top plate is the way to go besides fitting and welding a piece of structural steel inside the hole instead of using filler
Pretty good job. I would have done multi welds rather than that big cap at the end and stuck a plate on top big enough to clear the weld below and any badly effected heat zones but all in all good job.
Congratulations on a job well done "on the road". I've been welding since 1979-1980 after my license and I am constantly amazed at the greatly improved level of quality and safety of the job site's work.
Поверх места сварки ещё бы пластину наварить усиливающую со значительным нахлёстом, а то видно как новая трещина пошла совсем рядом с местом сварки предыдущего ремонта
Может быть первый ремонт когда был то её просто заварили, а сейчас он поставил пластину, но вовнутрь! Хз, нужно ли в таком случае наружная пластина!? Хотя для усиления может быть, но это не точно...
Looks good but it will crack again over time. But he probably just did it to keep it operational. Sometimes thats all the customer wants. Even with the proper repair, it might still cracks else where. Ive seen it plenty of times. My repairs haven't come back yet but it will.😂
Everthing needs to be cleaned and ground off.Take at least 3mm off the oxy cut material. Install backing plate inside. Pre-heat to at least 150 deg celc and keep at that temperature throughout proceedure. Use low hydrogen electrodes out of an oven and use single runs no big weaves, peen every run with needle gun, grind out the toes of weld on each run. When you've finished the capping runs, grind and sand off the excess weld material. Post heat weld areas and cool slowly to ambient temperature. This is only one method I've used over 45yrs in the industry. Once I was taught this method I've never had a fail with this type of repair and hopefully never will.
I love to watch welding videos just to read the comments of all the superwelders out there that will tell you all about how you’re not doing it the right way which is their way.
Doesn't change the fact there are better, worse. And the correct way to do things. Just because poor people make things work, that alone doesn't merit anything.
We're to begin at on how to fix this so it doesn't crack out again. On the vertical seem repair it needs to be cut out and a insert with radiused corners needs to be installed . Prepped and cleaned from all paint and grease. The top plate on the arm with the crack needs to be cut out past the end of the crack and the replacement plate needs to be smaller then the vertical insert . Top insert also need to have radiused corners too where it lies in the arm . Normal square edges on the outside of the arm . Leave a 3/32 inch gap around the insert bevels . Make sure it's clean and let her rip
To the un initiated the weld does indeed look excellent, BUT I completely agree with all the guys below. As a once heavy plant fitter, I too am very skeptical that the area to be welded was not beveled & there should have been, after cleaning, re-emforcing plates welded to the area. I remember doing similar to the old tipping links on J.C.Bs.
Very neat welding. I like the way you use a flap wheel to blend in your repairs. Nice finish. Also like your plasma cutting awesome job. The fabrications you did on the trucks and loading shovel are some of best I have seen. Please keep the video's coming. I am enjoying your repairs very much. Best wishes from jonsey south Wales GB
I know he used a gas axe for this vid. I was saying about his others as well where he does use the plasma has to be one of the best I have seen super neat cutting fabing and welding. Awesome
This "fix" will not hold for long. I bet it's probably already broken again in the same place since he posted this video. Without proper support scabbing over the affected area, he's just wasting time and putting unnecessary stress on a weakened arm.
Well all i can say is ic weld has repaired a cat excavator arm the same way cut the crack out insert a backing plate and weld it up. Do you think it's thier first attempt at these kind of repairs or what. They know what will hold otherwise they wouldn't do it. Although that said a fish plate over the repairs help a lot.
@ruthbees7214 I know exactly how they do it. They patch it up and paint it without any structural support, and that way, they can make it look like it was never damaged, then they sell it as quickly as possible.
Красиво-не спорю, но он прослабил стрелу еще больше, в этом месте и рядом с ним сейчас самое ломкое место, без накладных, такого сварного бы на его же кабеле повесели, те кто работает на технике
Grinder and paint make what a welder ain’t! If you’re going to sell it then fine but using it no doubt will break again. Should’ve plated this repair as others said already.
It would work to get you out of a hole. But a proper fix would be to cut out the full section and weld back in, there’s too much stress on that area for it to last (I hope it does like) but yeah, cut the full monty out and then glue it back 💪
Das ist eine Amateur Reparatur, keine Wurzel, zu breite Naht, keine Verstärkung der Reparaturstelle. Bei professioneller Reparatur ist die Reparaturstelle hinterher stabiler als das Original, das ist hier nicht gegeben.
Sometimes all the customer wants is to kick the can a little further down the road. This repair would allow them to finish the job or season without shutting down for too long.
Pretty weld, but it won't last. The metal around the cracks is stressed from the previous weld. Additionally, metal fatigue is an issue. To fix correctly, a six inch section on both sides of the break needs to be cut onto, and a filler plate that's beveled on all sides needs to be welded in place.
You were on the right track, until you put in those wide weave passes. That thick backing plate also creates a stress riser on the inside of the component, pretty much guaranteeing a future failure in the same area.
Weaving the vertical part of this job should have been done in at least two or three sections not one mass weave, I do not think this would pass X ray test
I thought that it was pretty but not structurally sound - knowing nothing about metalworking or welding, I came to the comments to see what those in the know thought. I'm happy to see that my belief is confirmed 😊👍
Perhaps the third* repair there will hold. * It's obvious that spot was repaired previously, so I'm assuming that the video is showing the 2nd time that location was repaired.
Never weave with stick welding like that lol. This is just a temp fix, a good repair should be done when it is given time to do so. This will crack again, no doubt.

No wonder the first repair didn't work 😂 my guy said "perfect welding job"
🤔No point in that! Well at least they know where it is going to break again😁
Maybe a few support plates stuck on after cleaning the mess up champ👍🏻🇭🇲

Should have put a gusset plate over the welded area
Que capricho de soldagem. Parabéns
I’m guessing the customer only wanted to pay to have that area patched up, not to fix it properly which costs more money 🤷♂️
Did the piece you put on the inside with a string stay or was it removed afterwards?
That is a backer plate. That is what fills the void inside and is the backside of the whole weld. It's permanent.
@@DXT61 oh cool, thanks
Never use a grinder without a guard safety first last and always
Im even a welder
But i def would have welded plate over that section
Air arc the Crack out, 1/4" root opening. Root opening is way too big, which will put more stress and heat into material. Not good!!
Súper hermosa obra de arte sapatero a su sapatos
It was a nice job he needed to add fish plates and weld it around the area because it's compromised
I've had to do this work often.
Если перед продажей.. Можно было снять фаску и заварить поглубже... А так наверно лопнет опять вдоль приварки
Как унас гензел сварится 😂
Не думаю что,на продажу.Потому что, техника работает там, наверное.Видно,рядом пачки арматуры и просто покрасил те места,что бы не ржавел. А так,отличный мастер! Там, как бы мелкосрочный ремонт что ли.
I like that you grind flush!! Great skills
Right or wrong, He made Zeus proud.
Меня поразило, очень круто
Great job Mr
Not sure about that giant Texas weave. Stringers are much stronger. Then fish plate it.
Great job! How do you prevent loose grease inside the boom from starting a fire while you are cutting out the hole?
Grease doesn't go in the arm
Awesome job keep up the great work 😊👍
A grinder and some paint makes me the welder I ain't.
It will not last.The arm is fatigued.
Very Impressive! Well Done!
