I swear Bob has forgotten more about welding than I will probably ever learn lol. He could weld a broken heart. I like how humble he is about a mistake that was made, and turned a mistake into a learning experience. That's a true teacher there.

You always have to use low hydrogen on cardiac welds.

The guy that taught me how to work on cars said that a man man that never made a mistake, never made anything.

Much respect for those welds Bob; not to mention your ability to teach.

I find, as a weld instructor, that it is absolute best practice to admit mistakes. You do a great job, Bob... never doubt that. It is ok to make a mistake, the real challenge is knowing how to correct them. Cheers from Canton, Ohio.

Bob we all make mistakes and a better man will admit it good video on this fix thumbs up.

Uncle Bob! your services are superb for welding learners like us. You are in our hearts. May you be happy we love you

I love this series. A lot of real world examples and demonstration. Great stuff for me to practice with my everlast powerarc welder. I really liked how he filled in that gap.

watched 1 sec and had to reply,been welding 40+ yrs.You butter it up! No big explanation needed!Done plenty of it for fitters who had cut something too short in Oil rig module construction! Buttering is an English term,to replacing material that has been cut too short!Lucky it wasnt wood!!!

As a newbie I found this fascinating - great recovery . We don't make mistakes, we have learning experiences.

I is devastated BOB made a mistake. My world just crashed. LOL Bobbie, you are my hero. You can do whatever you want, it's your show. You are on my bucket list of people I'd like to meet. You, Isaac (I C Weld), and Kurtis (CEE) and I probably won't get to meet any of you fellers!!!!! Well, I guy can dream.

Well done Bob. You are a true master of the trade . We need more of your vids.

Another great video sir. As previous subscribers have said "we all make mistakes" I am have just started to learn to weld and have found your videos to be the best on the net so far.

Good fix Bob. I enjoy your videos very much... keep'm coming.

Another well done video...thanks Bob!!!!!

Good to see what to do when things aren't perfect and how to recover without creating scrap, thanks!

Nice job Bob, really enjoy watching and learning from your video's (feel like I'm getting free welding classes). It's a joy to watch a pro like you in action. I've gotten a lot of educational information from these video's but welding is one of those skills where knowing and doing are two completely different things. Guess I gotta find me a cheap source of scrap metal to practice on.

I really appreciate that you make mistakes ,I'm a non certified welder in a factory building heavy haul trailers. and your videos help me alot I hope one day to just be good enough with experience to be able to have a good job. The only experience I have for welding was in highschool for ever go and the job I have now.

I am fixing my sagging floor in my crawlspace switch salvage H beams. So your video is excellent. Thank you.

Bob nice craftsmanship! When you were done there was no evidence of a mistake. I am a bit old school so in my book a 6010 is preferred on mild steel. Any way you want to slice it if this was done in the field that weld would be strong, functional and pretty. Good save!

Great demo as always, we do the same procedure for our skids but only with short arc and flux core

Nice job . Really hard on the legs to climb down 150 feet to turn machine down for up hill . Should send your students to potash mine in Carlsbad for some dirty field experience. When you did video of welding rusty metal I thought that was good steel where I work. Rusty and salt impregnated metal really makes me appreciate when we get new metal and I get to work in the shop. I love your videos and I have learned a lot. Thanks bud and don't check the flavor of the rods half way through hard on the nose or tounge

I learned a lot more from your mistake. Thanks for your honesty and courage to show your not perfect. A great teaching video!

Nice one bob! I have done 4mm 7018 vert up. I struggled with keeping it consistent, but i kept going to learn.

Very very good info. Thank you Bob

Brill arc shots and always learn watching your vids

I just got recommended this video and thought Bob was back, until I saw the upload date! Hope you're doing well, whatever you're doing, Bob!

I like it when you show how to fix things

oh my. That clear and nice filming of welding spot, so damn good)

Second time watching it and then I always learn something new.

Another great video Thanks

I've been working on roll off dumpsters for a couple of weeks now, plating over holes in the bottom and sides. These old, beat up dumpsters are so bent and crappy, there is literally no way to get plate to lay flat over an entire repair to fix it. Filling gaps has become the bane of my existence. The gap on that joint, Bob....that was nothing compared to the nightmare I've been welding in lately.....

nice recovery Bob..Old timer i used to work with used to cut beams so bad that i had to fill with 6010 4mm rods ..it was that or scrap everything! thanks for sharing buddy

I am always fascinated of the clear view on the welding process in your videos. Is this how you see it through your welding helmet in reality? With my welding helmet it is more or less guessing where to weld along. People told me that a cheap helmet is good enough for a occasional hobby welder but when I see your videos I doubt that.

It happens to the best of us buddy excellent video nice work

Great video

great video , everybody make mistakes very few admit to it , good or bad keep em coming a pleasure to watch

that was awesome, thanks

bad cuts an fit are a normal day..... you got a real old school relaxed movement and always a pleasure to watch. if i cut my own steel its always under size by 2 to 5 mm, for squaring up and peno purposes, weld seq keeps shit mostly square. tacks clamps and turnbukles do the rest cheers

Good save!✌

Thanks for the video and cool goatee goin on there Moffet

Never learned anything without making a mistake especially not fixing the mistake. Awesome!

For them tight corners, a drill and a cupped wire wheel gets right in there. Awesome demo.

As a rank amateur, I don't need to see you weld perfect cuts , I need to see how professionals deal with a butchers jobs like mine ,which you did , Thanks a lot Bob.

A REAL video! Great job on the fix and the video. I've f_(ked up some fits that make you scratch your head as in "WTF?", but figured out a fix and learned a lot about myself and my fitting/welding. Subscribed. Stay safe! H

Showing of your mistake and how to fix it, got you another sub

Looks mighty good to my untrained eye Sir!

Bob great video (as usual). I have a question, if the short piece was flipped so the gap between the web and the flange was at the top would you do the build up of the weld on the flange or on the web?

From what I've seen on site that's not bad at all. As an ironworker I seen my share of bad cuts and trust me that's not that bad.

We will all stop making mistakes one day. That's why I make as many as I can now !

Hey Bob, what would be the best joint configuration when joining two sections of beam end to end? Would this same sort of tongue and groove joint be best?Thanks

Everyone fucks up now and then, it's just some can fix it better than others. 😀 Good vid as usual Bob.

Its educational, People who don't make mistake will never learn 👍🏼.

Non ideal conditions. My Favorite!

It looks so easy

Good job, I might try to suggest going to 7014 it's a lot easier to weld with. And a vertical down is so close to the strength of a vertical up with 7018, it's good for using for people who can't seem to get the hang of a vertical up. You did have just a little bit too much of an overlap on that horizontal weld in the corner but that's the only question I had, it was a good-looking weld however.

Little known fact: every pound of weld rod contains at least 2 sticks of erasers.

Once you have done the root pass, how important is it to get the slag out from inside the joint before starting the other side? Is it critical, do you get out what you can or leave it?

nice!! 💪 👷🏻

Thank you.

I've had my first machine now for 4 months set for FCAW , an well I'm making mistakes such as bad fit up etc... money is tight and I'm 75% into a saddle cut fence gate frames using what I have on hand, recycled chain link top rail from the 70's. How can I deal with bad fit up gaps 1/4 - 3/8 an ensure that my welds are proper and solid. I've learned allot from watching but I'm curious when do you draw the line an decide to abandon you chunk of work an grab a fresh piece of scrap an try again?

A professional welder is not a man that can weld perfect. A professional welder is someone who can correct his mistakes and work around them.

Bob bob bob ur got a lot to learn

I just don't see it as a mistake. I see it as an opportunity to better ones self. And hey if you can fix it, all the more better!!!

what is the best ampere for 7018 and for 6010, when welding Ibeams? thanks

Hay Bob I'm curious as to how you would tackle a full pen weld on a I beam with 0.52 metal core

Hi everyone..,I noticed most steel constructions screw joints instead of weld..,does it mean screw or bolt is better than weld ? Tnx

Ahhh Bob, that wasn’t a mistake we all use to do that to get the penetration on the flange. Good video as usual.

Mantap bro....

Question, Esab Sentinel A50 or Miller T94?

Thanks for these - I love your videos. I have a question - at 7:00, why did you do the full weld uphill knowing you were going to blend the top of the piece then run downhill? Was the uphill for better penetration / weld profile? I am just an amateur, so downhill is always easier for me.

Uphill gives better penetration, and with 7018, all the flux runs down into the puddle if you try to downhill it.

I would have loved to have been one of bobs students. 👍👍

At the ship yard filling gaps is a thing you learn and relearn everyday

with 6010 { fast freeze } every time you wip the rod to far out of the puddle the puddle freezes before you come back in and its like a stop n start every time {boilermaker welder}

How many amps on the fill passes with the 6010

Hey Bob, just a few suggestions..... since this video and the preceding ones are showing structural skills, anyone doing this on the job should be welding per D1.1. Would it not be more educational to finish this job with commonly used D1.1 compliant field welding techniques such as - FP the flanges using steel or ceramic backing w/ runouts and 7018, E71-T1/T9 or E71-T8 all the way. (He-haw Bob's farm welding channel! All 6010 all the time!) People might say FCAW-G is not for field welding, but all of the large shipyards I have worked at use the same procedures and wires both in and out of the shop, all FCAW-G. And if you use a W section instead of an S shape the flanges won't be tapered.

Bob, Are you using AC? I ask because all I have is a 40 year old Lincoln buzz box. Works well and I am still learning thanks to you! Eric

Since he's running 6010, it's DC. 6010 and 6011 are basically the same, except that 6010 is DC only.

what about running a bead on the edge gap to build it up then fit and weld ?

For sum strange reason I love when u chip FF lol

the "mistake" you did, doesn't affect structarally the joint, you could even cope down to the "K-dimensions" of the beam. Once you weld the flange to a full penetration, that will take care of the moment forces, and the weld on the web will take care of the shear forces. There is not really a need to weld the "radial part" of the beam. (Structural Engeneer here, and a welder in training). Good job men, learning a lot from your videos

It’s only a mistake if you can’t fix it

These particulars are everyday type jobs...we all gotta build skids and their frames from time to time. I will use 1/8 6010 for tacks...then run 3/16 8010. It's oilfield so procedures are usually downhill.

Is there a reason for choosing 3/32's rods? I see a lot of that when I would have reached for an 1/8" 7018. Great fix btw...

Heat control would be my guess. 83-85 amps uphill is easier control than 95-105 with an 1/8" rod.

Could you do a video on what you should and shouldn't be able to see under the hood as far as shade wise? Not so much for us that have been welding for years but some of the young bucks.

Watching Bob weld is like watching Michaelangelo paint

Would another option have been to take that short piece with the wrong taper, alone without the other beam it'll be welded to, and add the missing metal back with a couple of weld beads along that edge where the gap would be then grind it a bit so the geometry fits tightly into the adjoining beam? Then it'd just be a couple of short flat position welds, which would be simpler?

I get the impression you ain't really happy about the cock up or the making of this video but your skills are awesome, you made that gap look like nothing to a beginner welder like myself.

Are you allowed to weld the k on an h beam

Can you use mig?

This last week I had 3/16-1/4 gap. On I beams to do. Shit sucked lol
