I am almost 68 years old and have been welding since I was 15, I have worked in boilers, medical incinerators , heavy equipment, chemical plants and structural welding. I have lost a lot of friends due to cancer. I HAVE BEEN VERY LUCKY SO FAR, but our youngest son at 27 seems to be following in my footsteps. I am making sure he has a fresh air filtered supply in his hood. Please protect yourself and be there for your children and invest in a filtered fresh air hood system, When you made the statement about the air arc " HEARS YOUR SIGN" You are a hard working professional and I really enjoy your presentations.
That's what I was thinking after seeing all those fumes and clouds of smoke coming off these jobs. I don't know if there are still chrome based paints applied, especially on old machines. That's a particular dangerous substance which made many people sick in the Netherlands.
When I look at the not so good old days, in the fabrication industry I think it behooves us old workers to impress upon the younger folks the hazards of the work place. In many cases we weren’t negligent, we just didn’t know the hazards. But we know better now. My godfather told me they used to wash their hands with PCB oil, it was good for taking dirt off. Many examples of things like this especially welding and fumes. It our job to tell the young workers things to watch out for.
YES, the fumes from burning metal are some of the most toxic you can be exposed to, I have watched friend die from infasema? Spelling? Not a teacher lol, COPD, as well as cancer. Untold numbers have had their coneias replaced. Please listen to what this gentalman says, PPE for life after the working stops.
Been with you since the beginning, and really respect your work. Your up there with the best on you tube; IC weld, CEE, and Alistairc123. Thank you for going thru the extra work to provide these videos.
@@gabrielmusewu5643 when It comes to real life heavy equipment welding/repair content, based on skill, quality, tool used, job difficulty, and frequency of content released, these dudes hold the top tier. There is no better, though there may be someone out there comparably as good as these guys, and if so, let me know. I’d love to check there channel out.
@@klue507 Am still on the hunt for someone who can be included on this list . Maybe Welding Artists was going to be amongst the best but now he last uploaded close to 7 months ago
I’ve been repairing heavy equipment for 40 years. We run 4, 55T Trail Kings daily and have experienced our share of damage to wear, stress and just abuse, but nothing to this extent. My techs and I can all weld confidently enough to ensure safety but none of us are welders in the “biblical” sense. In other words…we’re not hacks, can and do keep everything on the street turning a buck…safely or I walk away. I have also had my fair share of true welders come & go from my crew. You sir…are an artist. Guys like you…with genuine talent and the head to see in 4 dimensions in our industry are simply not there today. Your apprentice…better be kissing your ass daily.
I never would have thought i would sit here bingewatching your videos on a Saturday with some cold brew.. Awesome work my guy, nice to see your craftsmanship.
The moisture is a byproduct of the torch. Big fan of your stuff by the way. I don’t do it like you all the time but it’s fun and informative to see others at their trade.
I do this kind of work in the shop...I build escavator bkts and attachments up in Wisconsin..latley I've been wanting to go out on my own and do some line boring and repair in the feild..your setup and work quailty is great..really inspires me dude!
The water you see when you are preheating the metal as actually coming from the torch, one of the products of combustion is water vapor but on such a large piece that takes a really long time to heat up above the temperature that the vapor can condense on you’ll see it a lot of water dripping off while you’re heating, there’s still quite a few reasons to preheat just mentioning the metal isn’t holding that water before taking the torch to it
Nathan Hinz is correct, in addition, it is a result of the moisture in the air reacting to the temperature differential with relationship to the dewpoint vs material surface. The primary reason for preheat, is to slow the cooling rate while welding and after the weld is complete to allow the hydrogen in the weld region to migrate out of the weldment to prevent hydrogen induced cracking and delayed hydrogen cracking. The additional reasons to slow the cooling rate is to promote the production of fine grain structure in the weld region, improve ductile properties, reduce hardness, and improve toughness of the weld to prevent the occurrence of future cracks. "Pre-heat" should be maintained throughout the welding process, it is desirable to prevent high winds from cooling the weldment during and after the weld, a simple wrap with fiberglass blanket material is a good practice on very thick sections.
This channel and Cutting Edge engineering in Australia are the best. I wish a guy named Derek Dodge of Dodge Machining had a channel, he is also top notch and repairs and builds heavy equipment, line boring and welding etc.
I was involved in moving a 100 ton machine. It was the most insane rig I have ever seen in person. I believe it was a total of 122 wheels. The 4 axle Mack truck, then 3 stingers, the lowboy, then 3 more stingers with the last one being powered and steerable. There was a guy that sat in a booth on the last unit. It cost us $77k plus all the permits for 4 different states jacked it up to $120k. The restrictions on the route were also over the top. Only during daylight hours, frost laws, avoiding citied during rush hours, bridge speed limits...it was a 4 day trip to go 380 miles. I did a deep dive into the rig and brother let me tell you, you weren't joking about the stress those things go through. When the circus showed up, that rig was beat to hell. As good as they are, there's no escaping hitting curbs, the road and all the other hazards that our highways offer. But the driver just shrugged it off. He said after every job the whole thing goes into inspection and repair.
That trailer is probably rated for way over 100 ton. I'm surprised it cost that much we used to move 50 ton excavators all the time with a quad axle lowboy and triaxle kenworth. I know that double our weight but 100 tons isn't that much. It might seem like those trailers are under immense stress but they aren't they're made for that. The tensile strength if mild steel is about 36k lbs per square inch. 100 tons is only 200k. For those big steel beams that's nothing. It seems like alot to us because we are so small. Just like a car can weight 3-5k lbs that's a lot of weight on bearings but it's made for it. I'm not sure what the weight laws are by you but regardless I'm sure that was a fun move to witness. Oversize loads are the best
I've been watching for a while and come to the conclusion that you are a hell of a good welder. I wish I was 1/3 as good as you are. GOOD LUCK Hope get a lot of jobs you should as good as your are.
Just found your channel the other day. Immediately subscribed. You do nearly identical work. It's nice watching someone else doing the same job in a different way. Good luck
Impressive repair, great example of taking what could be overwhelming and breaking it down to manageable sections in an order that made sense and got the job done
Your talent is way beyond most welders I've seen I've worked in the printing industry an watched equipment be welded when breakage would happen & Now that printing is all but gone I'm a fork lift operater for a large glass manufacturing co. which is going through automation updating old equipment with new so I've seen quite a few welders in my time you by far are the best I've seen ! 👍👍
Looks like the line boring setup cut amazingly well with that deep depth of cut. Pretty impressive. Why did the provide you with the hole so undersized? A little bit I totally get, but that was a lot of material to remove!
I am surprised actually. Not many outfits would take something like that seriously. If its a very well done repair theyll go as long as they can with out following through with the replacement parts to be put on. Ive seen it time and time again with Commercial Transport companies. They will get it repaired correctly when its gone too far, such as: breaks again and causes a accident or further damages to their equipment. Im glad that this company didnt over step on their luck and used common sense to get it done as soon as the parts came in. Again theres outfits who will throw anyone under the bus and law suits for neglagence.
I was taught when gauging with the ARC gun you start on a corner or blow a hole. Then blow the molten steel away from you as your cutting.it leaves a much cleaner surfaces and a lot less clean up. I was also taught that to much heat is worse than not enough heat! Now I see why the trailer manufacturer said it would take several days to complete the replacements. They were allowing for the cooling of the surrounding metal before they started the welding process. I know how we are rushed to get the job done! There are set Procedures put into place and going there for a reason! This is something that was talk to me while I was in the United States, Navy. These procedures are there for a very good reason! The prices paid were always very high! More costly than gold or silver or any thing monetary related can buy! They were paid for in blood and others lives! I respect what you do but there are times you have to grow a pair and speak up while explaining to your customers that you are the expert they are counting on to get the job done in a safe and timely manner. You have to explain that you are protecting them as well as yourself and both good names! I was forced to retire after I was hurt in the USN. If your not going to do the job right then please don’t start it! Because if you do it is always going to be a mess to clean up! On some thing like your working… a failure could be most costly than you can possibly imagine!
Glad to see you are starting to wear a respirator. They don’t recommend facial hair but a well trimmed goatee is pretty close. I didn’t wear one for years but now I wear one religiously. Nice work brother-Another good one to showcase your skills.
Did you notice any orange paint underneath the red? Just curious, because if that trailer is based out of Clovis, and is about a early 2002-2004 manufacturer date, it just could be my old trailer. Some things like the bolt holes in the back end of the side rails were not a factory option back then on a Murray Goliath, and this one has them. They used to hold on wheel stops for 657 scraper front tires to go up against. It was sold to an out fit in Clovis about 2010 or so. Hmmmmm. Anyway, great video and awesome job on the repair. That is a BIF PITA repair. Good Job.
I've been in the heavy haul industry for 12 years now,pulling a cozad 9 axle for 8 of those years. One thing we always do is weld a sacrificial skid plate under those bosses. That way when you do drag it it's not wearing the bottom of those out. And it's a lot easier to replace a piece of plate on the bottom then replace the whole thing when it thins out enough and breaks.
As a brother craftsman it's great to see another craftsman with the stones to tackle the big repairs like this.. also kootos on the repertor use that paint and air arc swarf is nasty...
44:24 the water you found is probably condensation from your flames exhaust that condenced on the cold steel. Same reason you can see water drpping out of a car's cold exhaust, and the core reason behind contrails with airplanes. Use an electric heater and I bet you wont get water dripping from it. That said, I'm no welder, preheating it may be useful to get water out of areas you can't see or other reasons.
This might sound stupid to the people who do this for a living but I had NO clue you could cut such thick steel so easily. Really awesome to watch. Is the steel you put back on the trailer the same type that was cut off?
Pro.. you run a tight ship and cool to see ya getting shop eat. Just a truck and machine fan and blows me away abuse these expandos take. SO COOL seeing ya repair these amazing trailers! My guys say Cozad, Murray, Rackley, Siebert... all crack.
Production welding can and should be automated, but there will _always_ be a market for highly skilled individuals like yourself to keep things working properly.
It's so funny years ago I was converting cheap boat trailers into tree service trailers I thought I was the only guy to use 6011 to cut the metal haha awsome this was in late 80s early 90s kick ass
13:05 as an OSHA authorized outreach trainer, I have to advise you that your respirator would be a lot more effective if you shaved your beard. Its why firemen have mustaches and not beards, for if/when they wear SCBA. JUST KIDDING! You da man! You are a freaking artist with that air arc. The line boring is just 👨🍳 *mwah* love to see it done at such a high level with such nice equipment. I bet there is a short list of things you *can't* do. Subbed for knowledge transfer.
I worked for ro crane Corp which sold to simmon and then terex. When we had to weld or air arc in a really tight or enclosed spot they had one of those enclosed leather sock hoods. I only needed it with a leather coat once but they can come in handy
I fast forwarded through the parts I couldn't see well but watching you cut out that giant fitting was amazing. You aren't concerned with gas poisoning with the heliarc? I see you're wearing a particulate mask, that's good with the atomized metal, even outside. I've never done it before but it looks like fun. That boring tool doesn't need cooling lube? I enjoyed this. Thanks for the content.
Although at any rate, no matter what you have done a great job on this trailer for the client. The way you have done this job great work. Please protect yourself at all costs, cancer is no joke when it comes to welding, in any environment, all always have respirators when working on these types of projects i just had a sister inlaw die of bone cancer two days ago, anyway please be extra careful when doing these types of jobs you want to have a great retirement without too much inconvenience in retirement years. ??? Could you gotten more flat plates to take up the space between the part and the gap? Sincerely! R.S.V.
I would think that the lack of hardfacing on the bottom of the pin posses is a design flaw. But sometimes the builders of these trailers expect the trailers to be scrapped when cracks start to appear, thereby making repeat business for them.
You've got a lot of cool projects! One question though: wouldn't a fresh air system / helmet be better, especially when gauging? PPE is important, you've only got one you :)
I used air arc once to basically bore out a frozen cylinder pin under a truck (5th wheel lift cylinder on a yard dog). Took a lot of material out, and even a jack hammer wouldn't move it. Took a combination of heating the bracket bright red hot, squirting water inside the pin, and jack hammering. And got a piece of slag in my ear causing ear infection. I wish I had a mag drill to drill the pin out, could have been way easier
Why aren't the new pin bosses thicker to prevent a repeat failure? And, I would have thought these single point failure positions would have had a higher safety margin requirement.
That’s a great question. The customer wanted to supply the bosses. I had a bigger design all drawn up too. Some people like going back to OEM even if it doesn’t make sense.
