- Hey guys, I thought I would share a short video on Torch Scarfing. I'm not the best at it but I hope you are able to pick up a few pointers from this video. This was done a while back while I was rebuilding a front end loader bucket. I'll probably set it as the next recommended video, if you haven't seen it. Thanks for your support and please consider subbing.

Every trade in north america is/are hurting for new members and "Qualified Instructors". Someone give this man a sweet set up and good money. We need people like this before we loose craftsmen ability
Amen, a true skilled man... a dieing breed .........
He would make an excellent teacher
What we need are the wages of a good living and respect in the workplace and this would never be an issue.
Sadly a good teacher is invaluable but as a whole nobody wants to learn these skills anymore. The mindset is now why waste the time and effort on an old tractor bucket when you can just buy a brand new one from a third world country.
@@sixtyfiveford This is the practice by the capitalist ruling class known as imperialism.
Having been a heavy duty mechanic/welder for 30 plus years. I have done some scarfing with heavy equipment repairs. My dad was amazing with a torch and taught me how to torch scarf. Your technique reminds me a lot of my dad. He walks a perfectionist with a torch. And welding in general. Thanks for your videos. I enjoy watching another master welder and torch master that you are. Reminds me of watching my dad before I got into the trade
Yes he reminds me to of the old timers that had mastered their craft, I’ve been a heavy duty mechanic/ part time welder machinist 20 plus years now, my late father was a machinist, I run my own business and service truck, welding is something I’m more self taught then learned from anyone, something I wish I was exposed to more.
You are by far the most humble person I've seen on TH-cam. You never ask for subscribers, etc... Your knowledge and insight to fabrication welding is impeccable!!! I've watched a ton of your videos and it just dawned on me that I haven't subscribed. I'm definitely doing so now
I appreciate that. Thank you very much.
When you pick up a torch, it's like watching Rembrandt pick up a brush. When I hear you say something like "I'm not a pro at this" I chuckle to myself. I know I'm about to see something amazing. Your skill is only surpassed by your humility. Tells me your heart is as skilled as your hands.
Agreed ! Our host's canvas is steel.
Right? He is a surgeon with a torch.
reminds me of when I'd pick up girls at the bar... too bad those days are gone
The "problem" with your videos, is it's too much like hanging out with a friend at his shop and just doing a bit of work and learning a bit about welding. I've spend many hours bingeing on your videos.
Thanks for making them.
I remember when your channel had less than 5k subs. You're getting quite a following, and well deserved! I always enjoy watching you work, very nice!
Thanks for the info about scarfing! I am not a welder, just a typical home garage kind of guy, but love watching your work and appreciate your tidbits of technical information! Keep making videos, you have great style!
Judging from your self description, you have probably encountered wheel bearings on something where the inner bearing got hot and fused to the axle hub. Maybe an older car or a trailer or something.
I use this when I come across that. You can usually take a strip 180 degrees or so apart and use a chisel with a large hammer to remove them pretty easily. Just be careful to work on the bearing and not the spindle.
So practice up a bit. Get a thickish piece of metal, stack a few weld beads, and scarf them off. Eventually it will come in handy.
i have a short video on removing seized bearings.
@@sumduma55 A bit of personal experience with a chisel on a bearing race.... I had an inner bearing on the rear of my old tow truck seized to the axle stub. I didn’t think I needed the torch to split the bearing, I’ll just knock it loose with a chisel and a BFH. Short story is I was the emergency room a short while later getting the tip from my 1 inch cold chisel dug out of my forearm. The whole tip shattered off. I thought I’d been shot. I wasn’t sure if it just hit me or buried in my arm. I was sure after my dumbass put a magnet to my arm😂. I now use mild steel or brass to beat on hardened steel.
Every video you make is like a therapy session for me, the way you skillfully use the torch and the music. Excellent stuff.
Thanks for the video, I seemed to always wash side to side vs forward and back. I like it 🤙🏽
Their is an old saying that goes "watch and learn"...... there is so much that can be learnt by watching a skilled tradesman, such as yourself.....thanks for sharing.
IC's the man
Always a pleasure to visit over a video
WOW..... you're craftsmanship always amazes me....
I thought I knew what I was doing spending 13 years as a "welder/diesel" tech....but you have humbled me...
Thanks for all that you do...
Being a truck driver now
I enjoy watching you're work and keep thinking that I wished I had the opportunity to work with someone of your knowledge....
Thanks again 👍👍👍👍👍👍👍👍👍👍
I like the scarfing tips that are flat in one side, lay it down and drag. When your done is as clean as a CNC plasma.
Thanks for taking the time to show this. I just wish I could afford to refill my bottles lol
Thanks for another excellent video!
I've now purchased a gouging torch tip, & an air-arc torch because of you....🤣
I've welded/fabricated for years (farm/hobby) but wasn't aware of, or ever exposed to gouging until your videos.
You absolutely have the best gouging videos (crystal clear and easy to see what's happening) on YT. Thanks!
Fantastic!
Thank you. Every job you do is magic that I have never seen before.
We use to call that a gouging tip---used it a lot of times and it did a good job...Used it for ripping out heavy welds and so forth...Magic tool..
It is a gouging tip
I did use a torch to scarf some when I was a boiler maker been years .....you are a master with a torch always a pleasure to watch you work !
Please lease keep the videos coming I have learned so much from them and saved so much rime with torch work and gas usage down considerably. You lead by example. And it works. Keep up the good work.
Thank you for sharing your way of doing something!! I have learned alot by looking over your shoulder. It is always amazing to watch you work a torch!
I have learned so much from you. I bought an arc gouge this summer after watching you use one. I don't know how I lived without one now.
We touched on it in our apprenticeships. We didn't actually use it as such and were only really taught for a morning and given a quick go.
For me, one of the most memorable apprenticeship experiences was us heading over to the (coal mine) scrap yard. We wanted a sheet of thickish steel (1") so that we could practice punching through using a gas axe. It completely failed that day! Basically nothing would work - our instructor becoming more and more frustrated as the day dragged on. Every time we'd get a small pool going and hit the oxygen, it would all blow upover and not through. We tried everything we had - more/less pressures, different flow rates, various nozzles and even a beast of a gas axe that rarely saw the light of day. Weirdly, the sheet would cut fine from the side..
The instructor reckoned it was the steel sheet itself. It came from the mine's wash plant and although fairly rusted, he reckoned it was some type of stainless metal and perhaps even dual layered - like an armour skin.
Those early days and learning metalworking skills - they never leave you :)
Issac, iv just watched you do the extensive repair work on the boom, what a modest but talented man you are, please teach your lad all you no then he will always be in demand. Stan south of Edinburgh Scotland UK
The key to scarfing or "washing" with a torch is to have your oxygen and acetylene set high enough that once you have the metal hot enough to start flowing, the higher constant oxygen pressure will basically wash the fluid metal away. The oxygen should be set high enough at the bottle so you never have to hit the oxygen lever. The acetylene should also be set high enough to counter act the higher oxygen pressure in order for you to heat the metal faster and get a good flow of molten metal started. After a nice flow of molten metal is started and without using the lever, the higher O2 pressure (at the bottle) will start to make the metal flow or "wash" away pretty quickly. Then you can walk or slide the curved tip that is parallel with the base metal back and forth and forward to progress the flow off of the piece. You rinse and repeat until the remnant is gone and you are level with or have nothing left but the base metal.
If you are using the oxygen lever it can go south pretty quick by inadvertently cutting down into the base metal from hitting an inconsistent spot and changing the path of the pressure pushing/washing the molten metal away. The scarfing tip is curved so that you can rest it on the flat base metal behind what you want to scarf away. With the curve of the tip, it aligns the point of pressure parallel with the base metal to help prevent gouging passed the metal to be scarffed and down into the base metal (or piece that needs to remain intact or undamaged).
The reason why it is a dying art and a lot of people have a good general idea of how to do it, but don't quite get it right, is because it actually takes quite some time to get the metal hot enough to start flowing really good. Most contractors shy away from it for that very reason. It just takes too long to do it and do it correctly, so they would rather someone just bust out an arc gouge and skim it close, then grind it. But, the right person with a scarfing tip can do it without having to grind at all when it's done.
It's just a matter of how patient a person really is. It is a much cleaner way to remove excess steel IMO. As a Union Boilermaker if I have an option to scarf/wash remnants away that was left behind from a cut, I will do it every time. Mainly because it involves almost no grinding when complete.
We used #8 gouging tips for years to remove 3/4” wear plates from conveyor hopper cars and other wear points. After a while you can get almost surgical with them, if someone else is paying for the gas.
For your application you might want to carry a bigger molten puddle and wash from side to side to achieve a smoother finish Isaac.
, if someone else is paying for the gas.
I have seen those bent tips for years and never knew what they were for. Thanks for showing this 👍👍
I used them when I worked as a deck engineer to cut eyes of the deck that we welded in random places to lash equipment down. I seem to do better with the air arc setup and preferred that to clean off all the trip hazards. The air arc seemed to do better with rusty metals in the salt water environment.
Have you ever used 6011 to weld under water? I had to do that inside a barge to weld a crack between bulkheads. You better have some rubber boots on and wear nitrile gloves under your welding mitts or you get a little burst of energy here and there. If the hull was punctured we built a box out of steel plate around the hole. Add a 1" union for a drain to weld the top plate on and then install a plug to keep the sea water out. It could be plated in the dry dock later on.
Yep taken a number of hits from my Miller Trailblazer 325. Working out in the rain and snow. I now keep spare boots and gloves on the truck.
Thankfully I haven’t gotten shocked by my own welder yet. I was working on my fence and the ground was damp. I was feeling some tinging in my knee on the ground couldn’t figure out why until I looked where my ground and electrode were. I then pictured the current flowing and I’m in the middle.
While deployed to Iraq our welder was teaching me how to TIG. It was hot as hell so I was sweaty. I rested my forearms on the table and everytime I stepped on the pedal I'd get a zap through my elbow. Moved the ground clamp to the part after a couple hits lol.
Try 7014 and if you dip them in expoxy you have a pro rod. Also make sure you use a DC machine if you don't want to kill yourself. I welded. Underwater and cut tons of steel under water in the 70 s and 80 s. We used 400 amps with the old arc air rods .anyone can cut with Broco rods.
You set the standard! Amazing work!
It's a real pleasure to watch you work I have learned so much from you I wish there was more people like you in the trade
Simple and effective with a skilled worker behind the torch.
Just think if everyone thought like that!!!
Good work, take care!!!
I can “dig it” 😎
I've learned something new in every video
Excellent video! A true professional and artist with a torch and a lead. Reminds me so much of my uncle. Give him a box of 7018 and some good steel and he will produce something awesome.
Ha! I have one of those tips and didn't know what it was used for. Thought it was for cutting around corners. Thanks for the lesson!
If the process worked, and you’re happy with the results, then you did it right.
We always called that a washing tip, never heard any other names for it until now.
I’ve done quite a bit of that while working at a sand and gravel washer, having to trim old welds off of parts I was trying to reuse.
Did a lot of arc gouging also, but embedded sand in small cracks and pits in the metal seems to throw the gouging process off a little bit. The sand tries to turn to glass before it blows out, so the air stream seems to alter course around the glass beads.
my favorite Metal Master.......thanks Issac...cheers form Orlando, Florida, Paul
In Australia we call those a gouging tip when you have all the skills they work great 🇦🇺👨🏭
Very acceptable to most all of us. If you don't do it often, you of course get out of practice. Then you do a bit and by the time you are done, you about remember how to do it. Good video. These little "shorts" are great.
Thanks Isaac, any torch work requires years to perfect, if there is such a thing!:) I'm still learning and appreciate your videos. All of us, who earn our living working with our hands, can be proud!:)
More great tips Isaac, I don't do much scarfing at all but the tips are transferable. Thanks it helps.
1975 a Mexican Forman showed me that trick. He was a genius.
Man I’m always so amazed by your torch work. You are a surgeon with it. Grew up around a torch and welding on the farm and been a production welder now for the last five years and I am nowhere near as proficient as you haha. I’m trying to get out of the booth and go back to repair and do my own thing. With that being said you’re one of three guys I watch religiously and try to soak of as much information and techniques as possible. Thanks for putting everything online.
Wow, thanks. Im glad you gain something from the videos. thanks for the support.
@@ICWeld absolutely thanks for sharing so much of your knowledge and taking the time out of your day to bring us the content.
Everyone has a different way of doing things i think you did great
Great demo, Isaac.
For future notice. Do not trigger the oxygen when scarfing.
Simply hyper oxygenate the flame using the main valve on the mixing handle.
Think kind of like arc gouging.
I think I still have a scarfing tip left in my tool box from my time wrenching on transit mixers. We used this tip when removing the rivets from the fame and drum supports. It was better for this as the air arc was hard to control with 185 psi on the shop air and only 1/4" arc rods.
I have not seen it done this way before. It is very clean. I usually use a washing actionwith bigger pool of molten slag. I must say I like your results. I will try your way out tomorrow at the yard. I'm currently replacing a bunch of rotted structure off of a adjustable boat trailer from a salt water marina. This could help.
Excellent tutorial....
Nicely done Isaac.👍
I say if it works, it's not wrong.👌
Whenever you have to modify the technique for the circumstances, that's what it is. Definitely a lot quieter than arch gouging for sure.🤙
Cool teaching video! Thanks!
Omg that will save me soooo much grinding on some jobs great video!! Liked&subed
I looked at that tip and thought "Now how the hell is that ever supposed to work." 10 seconds later I thought "Ahhhh... " Thanks for the video.
You said you were by no means a pro at this; well, I think you're wrong about. You may be humble, but your skills excel. This is coming from a neighbor to the north, southern Oklahoma.
I don't know if you did it right or wrong but I do know that you did it allot better then I can. Thanks for another informative video.
Nice job👍
Looks good. Most times fanning when scarfing but your hand is steady. You did excellent job.
I like watching your very experience welder, Thanks
This would sure save money on buying special equipment for arc-gouging to get by with for special repairs and save on grinding the welds out.
Definitely worked better with more pressure and heated metal.
Thank you IC for sharing Scarfing, never seen it before. I only used a plasma arc to gouge, but that was on SS.
@@ohgeorgee7570 you can do the same on stainless using iron powder ;)
I'd like to see that ironpowder trick. How does it work?
Great video
nicely done
Hi Isaac, Nice performance. I dig it 😊
Ya did a job that was right for you. Right or wrong, ya got it done. That's all that matters ain't it👍
The one important thing you misses was using the torch as a hammer to knock the slag off lol. Great job on the video. We did alot of that in school with removing backing strips but haven't done it since
Brilliant
Sure do dig it thanks looks pretty decent to me.
Very interesting!
I like to start at one end and got it hot enough to start get the angle set then just drag the length of the weld. Similar to how you would cut it with a cutting tip. I enjoy your videos. Keep it up.
I do the same when doing repairs , it makes life a lot easier if you know how to use your torch
You know you’re good when you choose your tools based on how loud they are
Gee.. grinding with a torch .. impressive!
Thats slick
Thats cool
Looks good to me, have a good week end
Interesting to see scarfing being done. I have very little use for gas equipment l have and as such no opportunity to try scarfing.
I'm no professional welder, machinist by trade, but I always laid my torch haed as parallel as I could get it to my work surface and ran my oxygen up around 70 and it worked out really good. Providing you can do that with your work piece.
I hope this show doesn't impact your business .Thank you for all this knowledge we get each episode.
nice work.. thanks
Professor Isaac, class is now in session...
"I'm not an expert." Boy if that ain't a bunch of hot air then I don't know what is.
Brilliant video thank u 😍👏👏👏👏👏😀😀😀😀👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
I’ve only ever used a scarfing tip to remove 1-1/4” bolts. I normally use a #2 cutting tip and run 30psi on oxygen.
I love my plasma cutter for this job!
Either way is good.
Issac my instructor called it weld washing, not many people in the class caught on.🤔😉😊
I need to get a gouging tip. Been meaning to for a while. Another way that I learned to scarf something small off of material you don’t want to gouge is using a cutting tip, heat it up like normal and just turn your oxygen way up instead of using the cutting lever to scarf it off . Works great when you’re scarfing something small off or a small weld. Does not work well with thin base material.
heard about washing off welds as I work around steam locos and how every so many years during rebuilds the process was mentioned as per the boiler procedures and code and then redone, nice to see it done though I thought it would take fewer passes, I also thought that was called a torch gouging tip or is it called a scarfing tip, or are they differant
Gouging with a torch takes alot of skill and you can very easily run parts it's nothing like CAG or plasma gouging It takes alot of practice
Isaac: i'm not a pro
Pro's: Who do we call for advice? Answer: Isaac.
funny!! :)
FUCK YEAH!!! I just got this tip and I statred cutting off rivet heads on my truck frame. My first one went great and i torched part of the frame on my next one 😅. Its ok cuz Iam doing crack repairs right next to it . So iam excited to learn from such a rad dude!!!!
@icweld I love scarfing with my #gasaxe 13lb of acetylene works really well at keeping the material hot.
Vendo seus videos e aprendendo muito👍👍👍👍
Not sure how you could improve on the way you did it I don’t have an arc gouge and unless I’m at the shop I don’t have a plasma to use so the torch is my main unit for cutting out welds and fishing for the seam and with this method you really have a limit to smooth clean cutting ability but if you’re patient really you can take it down to the parent metal without much grinder work needed just have to balance quality over speed to meet the needs of the situation always a pleasure to watch you work
Worked a foundry maintenance for 20 years, know all about that tip.
Done lots of scarfing once you get used to it you don’t even take your finger off the trigger you just walk the tip down your plate but it definitely takes practice used to do it every day and it’s a real skill to have in your pocket when you need it!
Sorry your wrong Again You are a pro
It's not your, its you're
Omg why do people half to wine apout speeling so munch? Just shut up and stay out of people's faces PLEASE!!
@@vicferrari9380 its not speeling, its spelling
Isaac, what is the base metal you are removing? Sparks seem different from material you usually cut? Thanks for sharing your knowledge.
i digg it.
Scarfing takes a ton of practice, you tend to get good at it when you just run a welding rig with no compressor lol
I’ve learned how to scarf cut with just a regular torch tip by my dad, its a lot harder to do with if you don’t have the scarfing tip but the results are the same
Real reality video!!! Watch and learn!!! $$$$$$ thank you for your time!!!
