Hearing someone that’s been in the trade for decades saying “I’m learning” speaks a lot of a person and character. Well done Bob!
Learn something new every day. Thanks Bob! Your video series is highly beneficial.
Excellent content
A mistake by you is worth ten hours of trial and ERRORS for me and I learned it in twenty minutes in comfort! Thanks Bob for all you do for us liketobe welders and fabricators here in youtube land, well done!
Great video, Bob. If at all possible could you do a video on oxy propane cutting. I think a lot of people are going in that direction.
That's the neatest cut I've ever seen with gas, I dream of a cut like that.
Good video, welding is only part of the job! Not too many cutting & fabrication tips out on the tube, thanks.
Thank you bob. The last video help so much. Got over my fear and used the cutting torch. 4" circle. Not perfect but I did it and learned a lot. This video was no different. Thank you For taking the time for all of us learn.
Try a hole saw
The best part was the humble amount of appreciation you had for your own talent! after you made the cut!
I always cut a 1/4 inch piece of my beam or channel u can layout your cope perfectly on I beams I cut the flange out first then make my layout of cope on web impressed by Bob's torch skills
You're a true professional and everyone makes mistakes you knowing how to fix them and show everyone is what makes you a step above anyone can edit a video and act like they never did a mistake but you are a true professional and show us how to fix them
Gotta love the whistle. You know your cutting good when you hear that sound.
Another fantastic tutorial thanks for taking the time to publish it. Great quality easily understood even for a novice like me, delivery is right on the money.
Love it when you make mistakes, it means I make less!
That's why we leave them in the videos 🍻
Hey, Bob. Your screwups are learning experiences for US. Thanks for leaving them in because if we're paying attention, we can learn some new stuff usable in fab shops.
@@Welddotcom Seeing the result of this little booboo educates way better than a verbal remark to pay attention to this detail. So thanks for leaving it in the video.
Bob, that was yet another great video. Thanks again for sharing all the great content!
Love to see you weld it out now!
Bob, thanks! I learned a lot about layout from this video. Trying to layout and cope generally leaves me scratching my head and laying out the cuts on cardboard..
I love your little cheater bars. Will have to make some.
You're better at cutting steel than many are at cutting a cake or carving a turkey.
You make it look so easy, and it is once you develop your skills.
Thanks Dennis
Mistakes are nothing but accelerated learning! If you're not making mistakes, you ain't doin' nuthin...…and you sure as heck ain't learnin'! The more important thing is, do the mistakes repeat themselves, or do they drift off into that data storage area between your ears. Well played Robert, well played!
Excellent work.
10:21 your other boo boo is where the edge of the flange and the web meet there’s about a 16th of an inch cut inside the web on both sides. You put a decent size load on those joints and you’re gonna start having pressure cracks forming. Slightly ease up on the oxy if you don’t want to cut into the web when burning through it
Been there done that!!!

Really like your oxy cutting vids; it's nice to know that flame cutting can be a reasonably precise and clean manner to cut steel, as opposed to a way to produce a ragged, burnt mess of slag on the end of a workpiece that looks like Satan 'sharted' fire to cut the part in two.
Who'd have thunk it?
Now, could you do a vid where you demonstrate how it looks when incorrect tip size and pressures are used? That way, some of us at the, uh... "remedial" end of the spectrum can see why our cuts look like the devil's bowel movement.
At least, if sensible folk ever let us near a torch set again...
Hi Bob. I find your videos very educational. Could you do some on how best to deal with the imperfect world outside of the shop such as bad positions, obstructions, poor fits excessive gaps etc, adverse weather. I think it would be interesting to see how others deal with some of inconveniences of the real world.
Bob is one of the best. Love the vids.
I like that little torch guide Bob, good little joint to have in the gangbox
Been there done that too! From Timmins Ontario Canada.
The mistakes help us learn. I like the fact you don't start over and make it perfect. We all mess up even pros
Nice video, nice cuts, and educational 😉
you have a steady hand
This man is teaching . He a cool teacher I like his vids
Good instructions. Thanks.
Still a great job Bob - good to watch. :)
I loved that... "That would be accidentally ... accidentally... Great!" LOL. Every one of your videos has an enjoyable moment... :)
Not necessarily a mistake, it's more of an example of how it could have been done. Love the video.
Very nice tutorial, a good welder will fill that gap out
We all learn by mistakes. Thx for a great video
Solid video!
As a former Union Ironworker, that would be a reject, but hey, I've been there...the good thing is all these folks out here now know what not to do!
Razor!
i was going to say i think we do it a little different i the... union local 433
@@chazwikiwiki4636
I started out in 433!
right on bro
I don't know a thing about any of this. But, that was fun to watch.
Boo-boo? YOU'RE STILL ONE HELL OF A WELDER!! and even better TEACHER!
Good video great work
thx bob,,,great stuff
Great Job.....
very good lesson, mistakes are learning tools as well. thanks ,,
Really cool video and I like how you spoke to your boo boo. That tells me you are a good instructor. I don't have an oxy fuel setup yet but I do have an Everlast plasma cutter. Can you show how this coping might be different using a powerplasma cutter?
Hey bob watched a few of your videos enjoying them along, I’m only 15 and I’m really trying to get an apprenticeship in fabrication boilermaker, although I’ve only been able to stick weld a couple times and I really love it, any suggestions on what I can do to get an apprenticeship and maybe some videos explaining the basics of welding both MIG and stick
Nice video! 🛠🛠🛠🛠🔩
And yes clean the nozzle so it works like it should they have a tool fer it ok fer other too
Tapered flanges got ya !
Like the saying goes a dollar for mistakes been there done that good video on this thumbs up.
Grate! Thanks👍
Would love to see a video made for a CJP W-Beam splice! Joint-design, fit, weld. SMAW or Dual-Shield.
Hi Bob, I want to try this in my welding class but instead of SMAW I am going to use FCAW. I was wondering what size I-beam that is so I can ask my instructor to find a piece.
Bob, is there a product, some sort of paste or similar, that you can use to put between steel, such as for example 1/8” sheet onto square tubing, that will seal it and stop water ingress so I can just stitch weld it on an not have it catch fire and burn out like silicone or similar would?
Still a legend
Your mistake is still mo perfect, then anything that I could do in that situation. Great video Bob!! 👍👍
Hello Bob, is it possible to adjust the depth of the cut with the oxygen pressure or not to push the lever to far down?
Thank for replying.
Bob, how would you lay out that taper that you missed? I've been tracing beam profiles on cardboard to lay out coping cuts. That works OK, but it takes a lot of time. You knocked out your cuts fast and clean, except for the taper. I'd love to know how to layout and cut that fast
Grind a bevel and weld up the flanges, and forget the small gap at the radius. Most of the strength of that type of connections transmits through the flanges.
You cut the tab as though it was a universal column, but on an rsj. I have the tee shirt if you want to borrow it.
Universal Beams have parallel flanges..R.S.J.'S Rolled Steel Joists have tapered flanges..when you hear that sound with oxy all is good..
This guy is good
that fittng is 100x more better than what my ex co workers do..
This comes in handy pretty soon for me i guess.
"Holy smoke. Who does that?"
Meh.... when you make mistakes... it just helps boost confidence in the rest of us. :P Great video!
good comment
Personally, I cut the web first, then bevel the flange ever so slightly to reduce the chance of gouging the web
nice video
Okay Bob, your mistakes are better than most folks' best shots!
What cut would have made that fit correctly?
Nice
It may be simple and easy for you ..... But amazing to me .... :)
Every time I cut it drips all over the place! How is his so clean, almost surgical?
Do you perfer ox acetylene to plasma for this procedure?
Great video Bob, nice to see you are human and make mistakes like the rest of us :-)
Can u do one for a 45 degree angle
Done thousands of these beam copes,and that is not an unnecessary step i don't think.If your cutting angles on large parallel flange beams it is good procedure to not have nicks on your webs.
If you ain't fucking something up, you ain't learning.
Wow I don't know I've only been in the trade for 40 years.. my brother who is 9 years older than me.. taught me along with my dad who was in the trade for 45 years who learnt from his father... regardless with that torch tip and those settings...!! You could cut through 2-inch manganese!!! Just an observation
Off topic but I was wonder do you need a respirator/breathing protection when wielding or only during certain operations. I am new to welding and was just wondering
You should. You can't guarantee you will avoid 100% of the fumes even if you are outside or have an extractor. You just need a North or 3M half mask with a P100NL pancake respirator or equivalent. They fit under any helmet or face shield.
Bob, I do like any videos you make. They are so instructive and helpful for me. But let me ask you this question: Why often don't you button your shirt for safety?
What can I do if my pipe beveling machine doesn't have spacers to cut the exact pipe I have it's a mathy 1sa the problem Iam running into is the pipe I have is 5" and the beveler only came with 3"4"6"8" pipe spacers I have tried 4" 6 " spacer bolts that came with it and no success any suggestions
Call Mathey. They have them.
You French fried when you should've pizza'd bro.
6011 or mig can do the weld job done dont worry.
Bob welcome to the human race. You are in with a large group of very fine people. I am one of the oldest members with many patches for each goof up I have made. Welcome friend!!!
Hello from Bernie. Is there any reason you push the torch and not drag it?
Keeps the fire off of my feet.
😂
Removing rusted bolts without harming the metal surrounding it with oxyacetylene cutting torch
your mistake is our boost xD
Can't see it from my house!
So do you just fill in that gap?
No on a structural fabrication that would be an unacceptable fit up that could lead to weld failure and potential building collapse.
Cutting off the web for fit up is a good tip for me
Remember that one
Thanks
But forgetting the taper is not.
Its allright mr Bob, we forgive you!😁
It is or in the field
Again if no electricity is available????
The mistake was made because if wideflange beams vs S type . Which like channel have a standard taper on the flange of 9.48 degrees
I make more mistakes when I’m showing people how to do something. Your concentration isn’t completely on the work, though you may think it is, since you’re also concentrating on the learning process. It’s divided attention, and that usually leads to problems. Pointing out that work needs complete attention helps people learn to take things more seriously.
We’re all human beans!
Thanks for the video
Do you use flash back arrestors?
I had an oxy acetylene torch exploding in my hand early this year ( blowback) and the flash back arrestors stoped the flame before it went to the gas bottles.
Cheers from Australia
Yes, they're built.into the torch.
Wow that's scary. We require them on both ends of the hoses on the fuel and oxygen, in Canada. They get a little bulky on the torch end if you are using the screw on type so now, like Bob said you will find the built in.
your bad...lol i was watching you make that cut and seen the curve, and I was wondering if you were going to come back for the arch.... you had me scratching my head..but I'm always building something of modifying something the angle iron
fitment will make people cut the wrong side of the angle iron..
SO I always made it so I can avoid the wrong side cuts,
b5ut my torch is BUSTED so most everything is cut with saws
porta bands, saw-all, cutoff wheels, I WOULD like a plasma cutter,
subbed.....willing to learn! just built a SLAT WELDING TABLE...
looking forward to using it.. can't affordcanything new.., intrested in the (saw horse) stands ...to see how they work with the holes ....but it my first VIDEO with you
Where’s the next video with the taper coming off the web bud?
