"Basically, this is a whole bunch of cracks." Understatement of the day. The only thing really holding together was your fix from two years ago. Nicely done.
This machine is going to haunt you. With that many cracks you know . they’re gonna return. It’s like a boxer getting his bell rung, once it’s happened, it can happen again ,its harmonics
Hilarious that every rando on the internet thinks they know better than the guy in the video actually doing the repair. Glad to see you proved the naysayers wrong once again.
I use these videos to make me a better welder but I only work on my own machines so I never comment and never judge. Nearly forgot to mention that I am retired,70 years old and still learning.
I really enjoyed seeing the success of the "firiey fuel tank weld repair". The crack around the bolt circle was scary and you made it look like play. I'm sure glad to see some of the old iron restored for another few yards of dirt. Well done Good Sir!!!!!
You do good work in a craftsman manner. I am learning so much. I know it takes time and effort to make these videos and slows you down but they are very much appreciated.
I have always wanted to see the innards of a scraper and this is too cool! THANKS FOR TAKING TIME TO SHOW US!!!! I can only imagine the shocks and stresses the frame endures. Interesting to me that they form at the narrow points and unions! JUST fascinates me!
I love when the fulltime shop guys like to put in their 2 cents on field repairs. It's a piece of equipment used to quite literally move dirt/earth, doesnt need to fancy or pretty just strong enough to hold up to the abuse. Great work as always! Any chance you got a line boring job coming up I cant wait to see that S power in action and get a true honest review. Seems too good of a price to be super quality, I want to see if it would be a good avenue for my business in to line boring. Thanks Greg
I guess your channel was put onto my landing page because I watch a lot of Curtis and his Wife from the channel Cutting Edge Engineering. You two have a lot in common especially the part of doing the job the right way...cheers from Jersey!!!
Your field experience in all aspects of repairs is extremely impressive. Always a pleasure to look over the shoulder of a professional applying their trade!
An old mechanic would always tell me when I would come out to the job and weld up all the cracks on the cushion hitches on 657 B models that those cracks come from to much use when it was new . 😎. Nice work my friend. So thankful for the new mag drills . 😊
A welder’s dream. Chase rack and fill it. I use to have to fix cracks that ran into the mounting holes on 793 diff housings. I would make up a brass stud to screw into the hole then roll the weld metal into the open thread portion without arching on the studs. Once it cooled we could back the stud out and run a tap through the hole and the threads were good to go. Never had a mounting bolt strip out the threads.
It's crazy how much force is needed to make such a solid chunk of metal start to crack. I've never worked with heavy equipment before, and I'm surprised. You do really great work!
Way too go Greg!! Thanks to your classes. I know use might exclusively in the field on yellow iron crack repairs. It’s so much faster than the 7018 stick method.
As particular as you are about how to prep and get to good metal I had no doubt that those welds you did 2 yrs ago would hold ! You do a great job ! If I were 40 yrs younger I would want someone like you to train me to fabricate an work and weld metal ! Thanks for the update ! Stay Safe !
Lots of people don’t realize how long this prep would take with a normal size engine drive. I have a 300 amp machine and a 500 amp machine, 500 is the largest machine I have ever gouged with the step from 300-to 500 is amazing, can’t imagine 300 to 800 , !!!
Another 200 Amps and you could run those ridiculously large broom handle sized electrodes that some welding channels have shown off with! 1000 Amps! Absolutely insane!😮
Greg… we really enjoy your videos and like your other friends, always looking forward to your next projects. It’s amazing to us how these “ monster” machines can get these types of failures. Again many thanks and do take care…
Yes,all this crack is normal I saw lot worse here alberta most on winter work steel is cold and all twist and turn and uphill and downhill when job is over is hell job repair before next job.i saw cat dealers finning repair scraper near due wet dirt on huge job clean up due winter.this huge job but at least ready next job for contractor steady repair due a stress on machine.thanks video again.😊
Sweet how we can electrically erase a wield and then electrically glue it all back together again. Nice job jigging and man handling that Mag Drill. Cool stuff bud.
People who don’t repair scrapers for a living can say whatever they want about a repair. Scrapers cracking is just what they do from the amount of forces exerted onto them. Doesn’t matter how good of a job you do, the operators are gonna try their best to break it for you.
Well that's definitely a hell of a lot of cracks . I guess it show just how much stress these machines put up with . That was a lot of passes on that cross member. I guess that'll hold Thanks for showing how you do the repairs to your std and as your fiery tank is still good that means you know what ya doing ..lol. many thanks from an armchair viewer
Are you always expected to do such work as drilling and taping or even disassembly/ re-assembly? So often you seem to do more than just weld work. Do many welders leave this type of work to the company's mechanics to do?
That is what sets me apart from everyone else. Most welders don’t do anything but weld. I love wrenching and taking stuff apart so why not offer it as a service as well. One phone call does it all!
When I was a kid I used to wait for the next episode of dukes of hazzard with so much anticipation. Now I wait you and icwelds videos. What part of Cali are you in? I’m from Tennessee but Sacramento area is my second home. I feel like your in the valley north of LA
Nice work, my boss thinks welding shouldn’t take that long and tries to rush me when I do it lol. I do go to school for it many years ago passed all the tests it could never find a good job doing it for a living so I just do it part time or when something breaks at work. I use my own welders grinders etc etc. some people never learn
If your boss doesn't appreciate your efforts at work to try and save them some money by repairing things for him, just stop doing that work, say that you are too busy with your ordinary work and let him try and find a reliable welder or boilermaker. Once he starts seeing expensive invoices, he might change his tune and if not then you have saved yourself from his nagging and aggravation. Yes, that is a poor attitude, your boss is not valuing your welding skills so withdraw them until he does. I work maintenance at a large private school in Melbourne, Australia and I have eased back on how much welding and metal work that I do and I still have metalwork jobs to do and others get handed over to our fence contractor. Being understaffed, my jobs list has been steadily growing in red on my tablet, but I can only get through so much work in a 8 hour day by 5 days per week. They have not really wanted to pay overtime, so jobs get done when they can and after urgent jobs have pushed them down the list again. I hope that my comments have helped. Mark from Melbourne Australia 🇦🇺
I am not a welder! I weld to repair stuff around the ranches. But how would I know what kind of material would need pre heat. I know I don’t repair anything that I think Would need it. Mostly repair disks and other farm equipment and cattle pens and trailers. Great videos!!!
Just think anything super thick, like 1” or more. Or something that will have a lot of twisting stress. Pre heat and even post heat can help relax the metal.
Gday mate, I’m catching up slowly on the back log of your videos and you level of skill is just sublime. I also find that I get lots of info on just how you set your work up which I find has helped me heaps. One day when you get the chance could you just explain how you build your welds up, like in that big section you just did there as I would like to know how you work it out, why you do it, when do you decide to go up or down the weld etc. I guess a lot of it is from years of practice and experience but it must be based on something. I always have a little chuckle too when you linish a surface back and then spot weld little imperfections up and linish them again, I thought I was being anal when I do it but feel I have the blessing of the master. Anyway, you work is beyond reproach, you are an artisan and I love you basic, simple commentaries. Many thanks
Another superb repair done in the field. Did you use dual shield flux core? Amazing how much stress one of those graders takes, and even more amazing is that the welds you’ve done will hold under those stresses. Probably stronger than it came from the factory. Hope your cold gets better soon, and your videos are most appreciated!
Great job Greg Looks like you went back to your Milwaukee mag drill I guess if Caterpillar and any other heavy equipment companies,built machinery to last,yourself and a lot of others would be out of work 😂😂😂
Great video, very interesting! I'm curious how you knew exactly where to drill those holes. Seems like it would be difficult to get them exact. Which is why you're the pro, not me! Thanks for sharing these vids, they are really interesting.
@@OFW Fair enough! You cut the clip like drilling the hole was the difficult part... but even the prettiest hole doesn't do no good in the wrong spot haha
Some questions: What is the cause of the the cracks? Metal fatigue? As a former offshore fabricator I understand that the weld is stronger than the metal next to it and a crack could appear next to the new weld. Would reinforcement plates reduce the risk of new cracks in the same areas or will the forces applied to the frame make cracks next to the reinforcement plates? Thank you for the video. Learning every time.
Cracks happen from thousands of hours of hard use and a bad design might play a role in that too. I don’t think plates would work that well. Plus this customer wants everything to look at original as possible.
Is the new welding unit you purchased a few episodes back ? Looked like you were welding dual shield with the brushes between passes. Hope the new unit is proving to be a good purchase, excellent work as always.
Makes one appreciate the forces involved in these huge machines. Do you think the metal in this rig was over hardened? or just work hardened? or just not thick enough? or operated improperly? or just a bad design?
Just wanted to know have you ever used a Haollow air ark rod the oxygen go's through the middle of it that is what I use under water to cut.just curious thanks be safe and have a great day Sam and love your videos
I know this isn't code work but adding some pre & post heat after arc gouging sounds excessive but its beneficial. The toe cracks looked similar to a hydrogen induced crack. Do you guys do any PT 24hrs after the repair?
Hi Greg, I have a question can I use a 1 hp 3850 rpm motor with a worm gear for the line boring . Will the motor rotate the bar ? If the bar is 50*1600 mm
I am truly just interested on how much on average a job like this would cost to a construction company. I would greatly appreciate some transparency on this one. Thanks!
Wow man, that scraper has been through it!! How do you determine what wire to use on different parts of the machine? Like when there’s a cast iron part welded to plate or cast steel welded to plate?
@@OFW Yeh im aware its not up to you, you just do it if you get paid. But im thinking for the customer, when does it stop being profitable with keeping repairing old stuff. Its both down time, and repair cost.
Another awesome video. Greg was wondering though couldn’t tell from the video but it looks like you were using 1/4 “ carbons gouging And if you were, I was wondering why with that pretty awesome 800 airpack you won’t be using 3/8 or maybe jumping up to 1/2 “ carbons ? I’ve used 3/8 hundreds of times with my 500 amp machine only a few times have I used the 1/2s And I was also wondering why you chose to use the ole fashion carbons instead of that plasma for gouging Just Curious to why you choose one over the other and Again awesome work good job and keep the videos coming
OK gotcha I like to 5/16 myself. I use a lot more of them than the three eights but when I need them I use them. . Have you ever use the 3/8 flat carbons ? After you knock that crossmember off you put them in there and you just hit those snots and goobers on the side wall takes them right down nice and flat. You basically don’t even have to grind , They’re also great for chamfering round bar or pieces of plate j I use them all the time if I have to make a small bevel on a piece of plate or flat bar

Hey honest question why did you replace the crossmember Was it just too worn out And deformed to repair awesome job by the way
It was cracked and had been repaired many times. It’s a common failure point. The customer wanted to try a new one.
What’s your thoughts on using duel shield on thin material. Like 14 gauge. Specifically a boom section on a man lift
I don’t think it’s necessary. But some .045 dual shield could probably run pretty nicely if you had it set right.
Nice job on the bolt circle
Excellent work, awesome video.
Hi Greg, I have a question can I use a 1 hp 3850 rpm motor with a worm gear for the line boring . Will the motor rotate the bar ? If the bar is 50*1600 mm
I think it all comes down to the feed box. Should have gear reduction. I believe my motors are 1,000 rpm
@@OFW Thank you for the answer❤️. I agree with you abut the feed box . with worm gear it will turn the extra RPM to torque
God bless you Greg... please don't work yourself to death & kick that cough
I have to ask. At what point is it no longer feasible to keep repairing the vehicle?
They repair some pretty tore up stuff. I imagine this isn’t even close to that.

Do you gotta run pulsed to do that or can you just run normal settings? I always thought you had to run uphill with dual shield.@@OFW
@@scrapmanindustries Normal settings. I wouldn’t run it vertical down but a slight down hill is fine. If it starts to puddle up then move faster.
I work for a mine doing heavy equipment repair but I really want to learn how to do this kind of stuff too
On some of these jobs I almost expected you to pull out a ladle of molten metal and just dump it into these large cracks!
Wow man, that scraper has been through it!!
How do you determine what wire to use on different parts of the machine? Like when there’s a cast iron part welded to plate or cast steel welded to plate?
Well cast iron is a different animal in itself. But I try to match it to factory specifications.
So are you able to get weld procedures from the equipment manufacturer?
@@bigcountry1009 sometimes
Good grief! If that scrapers name isn't Humpty Dumpty it oughtta be! 😅
Where to start on a job like that, well done!
At what point, if any, do you stop trying to fix a frame that keeps cracking? Wont this just happen again in the future?
It’s a never ending battle. Just keep chasing cracks. Up to the customer if they want to keep the beast alive.
@@OFW Yeh im aware its not up to you, you just do it if you get paid. But im thinking for the customer, when does it stop being profitable with keeping repairing old stuff. Its both down time, and repair cost.
@@djdeaf13 well considering these machines can make a couple thousand dollars a day on rent. It Has to be a pretty extreme failure for them to retire.
Another awesome video. Greg was wondering though couldn’t tell from the video but it looks like you were using 1/4 “ carbons gouging And if you were, I was wondering why with that pretty awesome 800 airpack you won’t be using 3/8 or maybe jumping up to 1/2 “ carbons ? I’ve used 3/8 hundreds of times with my 500 amp machine only a few times have I used the 1/2s And I was also wondering why you chose to use the ole fashion carbons instead of that plasma for gouging Just Curious to why you choose one over the other and Again awesome work good job and keep the videos coming
I was using 5/16 and 3/8. I almost used the plasma but the problem is, I have too many options. I like to change it up.
OK gotcha I like to 5/16 myself. I use a lot more of them than the three eights but when I need them I use them. . Have you ever use the 3/8 flat carbons ? After you knock that crossmember off you put them in there and you just hit those snots and goobers on the side wall takes them right down nice and flat. You basically don’t even have to grind , They’re also great for chamfering round bar or pieces of plate j I use them all the time if I have to make a small bevel on a piece of plate or flat bar

Does the customer ever require any NDT? Maybe at a minimum MT or PT. Or UT.
No. Every now and then I get jobs that require certain certs.
