another broken excavator weld repair

[@arvin7528]

Thanks for this vid. I am about to start my work as service advisor by December and this vid maybe used for the future. I am from welding industry a technical engineer from Lincoln Electric. Great video!

[@allistairc123]

Awesome bud thanks for aupport

[@Rich206L]

You made a very interesting comment about the lack of pre-heat during manufacture. I guess you don't get much for several hundred thousand pounds anymore, do we? I admire you ethic about always giving it back better and stronger than it was originally made! Hoping to see you hit 100K subs very soon! Rich

[@NICK-uy3nl]

That's what you call a PROPER repair rather than just a weld repair

[@mrsock3380]

I knew you would get comments about covering the chrome, considering you do this for a living you would think people would ask what you use rather than telling you what you need to do.

[@timebert6141]

The quality of your workmanship forced me to subscribe! I used to do this type of work for a living but I lazy assed out and went to work welding in a factory.

[@eliotmansfield]

grease means that the operator actually cared about his tool

[@peteacher52]

True enough. However, I as well as yourself, clean the teeth before visiting the dentist. How about the same courtesy for the engineer?

[@stewartcluley9524]

Another great video. 👍 Love seeing some real-life weld repairs on heavy kit. Keep em coming. 👨🏻‍🏭

[@brianburdine4620]

Couldn’t help but notice you covered the cab glass up. Once had an intern in the shop doing some welding/grinding on the stick of an excavator, he sent so many sparks into that front cab glass we had to replace it!

[@markfryer9880]

It's the same thing on building sites, people with grinders and welders, not thinking about where their sparks are going. They end up embedding grinding debris into the glass and the only solution is to replace the glass. A couple of minutes spent covering things up saves a lot of anger, grief and expense later on.

[@super6954]

Ok so the guys an intern that generally means some of them aren't really experienced in floor sweeping and tea making, or just graduated from that level, or can read a book and pass exams but practically they are useless in the real world. Why wasn't somebody supervising that was experienced in grinding not pointing out about sparks and windows, it wasn't totally his fault was it !

[@josephlockhart8338]

[@darrellroeters4951]

The slag rolls off in one piece, excellent welding.

[@jackdawg4579]

thanks for explaining why you did the repair that way, I was just wondering " at what point is it more economical to just cut it off and start again". Good tip on the anti spatter spray as well!

[@allistairc123]

When the repair strength has no further potential to be stronger than original, it's time for complete replacement.

[@jwoodyr1]

With just one side of each plate beveled, how did you keep the work from drawing and locking the pin in place? Thanks and thanks for sharing! Loved the video.

[@allistairc123]

Usually brace it untill cold then remove brace but I'll admit , I forgot and it did pull in abit but persuaded ram to go back in with a few thumps needless to say don't need the shims

[@warrenjones744]

I just found your channel. Pretty good stuff. I am also a welder/machinist here in the US working on heavy stuff. My guess is that repair would have been just fine without the supporting plates. But those plates will insure it will break someplace else 😀 cheers🍻

Great job Allistair keep the vids coming I know there time consuming and times precious in our game but great to see 👍🏻

do i see a crack on 12:40 at rod end where chrome ends?

[@landroveraddict2457]

I really appreciated the explanation of your methodology. Thank you @10:54 what was the reasoning for not tying the new plate all the way along the seem?

[@allistairc123]

Thanks bud aprecieate it. The new plate was fully welded on inside, on the outside only the broken weld was repaired with some overlap. The original unbroken weld was perfect

G'day there , Thanks for sharing this repair with us , i just love these major repairs . Theres no doubt about your skills ,the welds n prep work speak for themselves . Im guessing you enjoyed a holiday down under recently ,, cos i got a good laugh from the root weld joke . But were good at mathematics too , We learn from an early age that if you subtract ,divide, then add give it a good square root, n it will multiply ,, if ya not carefull. Love your channel ,,keep on bringing it .. Much Respect from Down Under

H ha ,yeah bud, straya my fave place on earth, was lucky to get a couple of years workingplaying out there! Thanks for support, appreciate it.

[@timebert6141]

You can use the soot from straight acetylene burning to protect the chrome. Not to say it works better but good men run out of supplies. Very nice repair! I like your ideas on pre heat and the plate you added for strength was masterfully done as well.

[@colonialroofingofnorthcaro441]

I know this is a sensitive question but as a new shop that I'm trying to build up, what would you say a good price or a way to figure a good charge and fair for jons like this, ibe got a crane boom I've got to start tomorrow and I just dont know what the going rates are for projects like this, thanks for the vids and hope to hear from you soon , Michael

[@allistairc123]

Thanks for support bud. Tricky one that .. can you get a further education qualification or training

[@PMPCMining]

Question, why use wire feed dual shield over stick welding? Stick welding had a higher rating for strength. Just a question.

[@adammarshallroofer]

Easier out of position welding and its much faster than stick welding.

[@michaelrodgers6559]

Looks excellent! What wire do you run for yellow steel (equipment like this)? I've run a ton of Lincoln NR233 (d1.8 spec for earthquake structural) sized at .072" and I would think it would do the trick. What were your preheat and interpass temperatures? I'm assuming you gouged the backs out of your roots and filled them back in, yeah?

[@allistairc123]

Good old 10 minus mild steel no preheat and not enough passes to worry about over temp, run mild steel solid wire nothin fancy.

[@allistairc123]

And yeah always back gouge where I can

[@marcuscicero9587]

the prep work involved in welding has got to be more time consuming than the welding itself

Your right. Snap-on's had its day. Milwaukee is the way to go and I love mine 😊

[@mikeysgarage3697]

An old-hand trick for protecting the chromed rods was covering them in acetylene soot, back in't day before anti-spatter spray, lol!

[@allistairc123]

Cool not herd that one!

[@tuttebelleke]

How do you apply the acetylene soot? Straight with an oxygen-poor flame? Doesn't that burn the hydraulic oil layer for a part on the rods?

[@KrikkitWarlord]

@@tuttebelleke If the flame is rich enough it'll be super cool anyway, probably not hot enough to take up the hyd oil left behind!

[@semicolon747]

not sure if it’s been mentioned here, but the broken grease point @ 11.02 will be a huge contributor to the damage done to this machine by a less than mindful operator. Lease company machines are a far cry from a bright owner operator’s steed . Lovely repair detail, no need for new lugs. I am surprised you didn’t grind your welds back for style on your class 1, under the finish coat of primer and paint cover? Great video 👍

Love ur repair videos Alistair. Excuse me nievety but whats the difference between the flux core mig wire your using there and gassless flux core wire

[@allistairc123]

The flux core with gas is a positional wire, its very very easy to to weld vertical and overhead

Love seeing another side of the metalworking trades. Kinda surprised you didn't use more solvents to knock that grease out. At least in my shop, some brake cleaner or contact cleaner is the typical way to deal with grease.

Great video again . Did you weld at the welds with the flux core wire or just the first run . Why do you use hardox 450 plate . Would s355j2+n plate be as strong and cheaper then hardox and the metals would be same in welding.. with the flux core wire do use welding gas or just the wire . Do you have to change the welding liner in the touch and tips . I tried about 20 Years ago using a Lincoln plant and wire in vertical up in a single v 15 mm plate in a test pei

[@hymac3589]

I tried with a Lincoln plant and wire in vertical single v in 15 mm plate in a test . I found it very quick put I was getting slag traps or pin holes and found it very hard cap the final run . And the welding gloves were next thing to going on fire 🔥 hour the gloves fucked. It's so long ago think the welding touch was different then a mig touch . Keep video coming . All the best from Carlow😄

[@allistairc123]

I used th hardox first because it's super strong, that allows me to use much thinner material in a tight clearance scenario, I just done a couple of flat welds and tacks with solid before I switched over to flux core.

[@allistairc123]

The flux core runs on sametips and liners as solid wire, it runs with same gas also, the function of the flux is to aid positional welds as much as shield.

Its mint that the plates didn't pull so you could remove the pin after welding and put it back in, it had me wondering when you said youd weld it with the pin in, great job! ps flux core is my favourite wire too

[@timbow50]

Some preheat even on this thickness for a MIG weld is probably the thing to do. I would heat even stick welding the root pass myself. To me just a little insurance of good penetration.

[@peteacher52]

Very good! I've just had a gander at JCB's website where the boasting about the superior strength of the steel used that will defy failure even under the most arduous conditions, is almost laughable in light of what Alistair has just done! It would be good to know if Cat, Volvo and others of similar size have the same failure rate at the same hours of work.

[@benabusthethird9751]

[@job38four10]

I'd be awful nervous welding something like that without a pin going through the ram ears and I'd try to get most of the welding done before taking pin out. 3M add-flows work good but extremely expensive...

I would imagine that you would fall on the floor somebody told you to do it right once. At least they know where it's going to fail the next time again.

[@chiphalvorsen4252]

This is another great example to my earlier question about "Why don't the Manufactures put more strength into these stress points" Your answer was awesome and it rears its ugly head again. Is JCB a high quality Manufacturer? and if so, do all of these have the same problems or is one the clear cut favorite IYO?!

[@allistairc123]

They are a very innovative manufacturer, they produce a lot of specalised machines that others don't

[@richhowe7193]

All manufacturers have failures but if they are fairly isolated incidents and at high machine hours it doesn’t warrant a redesign and adding more cost to the machine. This could have been a manufacturing defect but if caught at an early stage it would have been a simple fix. The crack didn’t happen overnight and there’s enough symptoms to catch the fault before failure

[@xanderfuchsbichler3206]

Did you run a solid wire root?

[@allistairc123]

No just tacked it and done the base run with solid first. Can do whole job with ether but flux core much faster

[@super6954]

Thanks for another good video, welders hate grease, but as a mechanic if some guys actually used it, it would help me no end when the pins /bushings weren't all chewed to crap needing a machine shop and a welder. Or the pins are seized in so tight it's a days fight getting them out to do a repair. Do you see loads of the same repairs on those model machines or is part of it the guy in the seat pulling the controls, if it's him it will be back when he busts the next weakest link in that boom doing the same thing.
