Like sitting in shop class! Plain, simple English tells me that the instructor truly understands the subject. Well done.
I'm definitely guilty of not cleaning my metal enough before welding with my everlast. Thanks for the reminders about proper preparation.
Thank you for doing this video and showing us how important cleaning is. All too often I have run across people on the Internet saying "oh just crank up the amperage and burn through the mill-scale". They believe they are saving money by illuminating a step. I would'nt want to see their creations fail structurally. I prefer absolutely clean material for better fusion, thanks Bob for a good video. I taught for over 25 years with hearing plugs of all kinds in my ears, I set good examples for my students and I can still hear a pin drop however my wife and others say, I have selective hearing!
Thank you for your video. I am looking forward to part 2 to see the contrast between prepped and non prepped welds.
Great video BOB, as always. Basics explained, before welding. Thank you, sir.
Thanks MATTHEW
This was very helpful. Thank you.
Great video. Looking forward to part two.
Bob - Any chance you could do a video covering different types of metals, how they are used and the best welding technique (MIG/TIG/STICK) would be used for them. For example, when would someone chose Hastalloy, Iconel or P & O metals for a certain project? Which welding methods work best for these types of materials? I'm brand new to welding and trying to learn about the various metals and alloys, and I figure I may not be the only one who would like to learn more. I appreciate all your videos, thanks for making them.
Great video! I've watched it 2 or 3 times but the part where he goes "we have a camera GIRL today, how about that-" and then makes that woowoowoo noise makes me laugh every time.
Another fine video... chomping at the big for the next one. I wish I could come down and take some classes.
Dave Dunn We'd like to have you.
Hearing protection, yes ! If you want or need to hear at the same time, the ear muffs that are made for shooting are the real answer. You can talk and make noise at the same time. What have is a microphone on the outside and speaker inside with a max volume setting. The fanciest ones claim that you could hear heavy breathing on the other side of a wall, but those are police / combat quality & very pricey. Mine came from Dillon Precision reloading & currently run $135 & worth every cent.
Thank you for the information, I like your video's.
Flapper discs are the best!
I'd only use that hard one if I needed to take a bunch off like a heavy weld bead.
You bring up a lot of good points.Look forward to watching your videos every week.Where
do you get your small wire brushes from?
bob litchko Local weld supply store. Great for cleaning the grooves on golf clubs too.
Great video...... thanks!!!!
nice video. Just simple question: how to clean stainles for TIG welding cut on plasma? How to clean edges?
Hello Bob. I have a set of molded silicone earplugs with a db filter. All workshop noise is dampend, but human speach is still clear.
Thanks Bob
Thanks BoB!!
Hey bob can you do a video on some big diameter fluxcore wire? Im in the process of taking tests for a new job. We have been using .072 and 5/64 lincoln nr233 and hobart xlr8 fabshield. We have been running tests on 1" plate in 2 3 4 g positions. Toughest one for me so far is the 2 g, 1" plates top one with 30 degree bevel and bottom one is a square end, 3/8" root gap with backing strip. Im having problems with fusion in the root. Any knowledge you can share with us on this wave of heavy diameter flux core for industrial construction would be awesome!
Thanks for the video. Didn’t hear bead blasting mentioned for prepping. Nowadays I always bead blast my carbon steel prior to welding. So much easier and less dirty when done in blasting cabinet. I use aluminum oxide blasting media. I`m not sure though is there a possibility of steel contamination that could affect the weld. However never seen any problems of that when tig welding of the blasted steel. On the other hand, the flap disk is Al oxide as well so probably makes no differences.
Ccorniit I'll bead blast carbon but not aluminum.
More good info Bob.
Nice video sir
Hey Bob. You're videos have helped me in numerous ways to help me pass my aws and state tests. I recently went out in the field for first time as a structural steel welder. I failed miserably. Is it possible you can show how to weld with gaps? Or a lap joint around a rusty ibeam? I would set my practice plates the proper way, clean and tight. Well in the field it was a different story. Please help. Thank you.
Interested to hear how you got on and if you're still doing it now?
You should try musicians ear protection. You lower decidels, but keep a decent EQ so you hear what's going on.
+Weld.com try alpinehearingprotection.com/earplugs/worksafe/ you should find 'em on Amazon too.
How far back from where you are welding do you need to clean the metal, or do you just need to clean the area the weld will go?
Technically you need to clean just the area the weld will go, but about one inch cleaned around the welds used to be handy.
Hi Bob, many, many years ago when I first learned how to weld aluminum I was told to warm it up a bit before brushing it with SS wire brush. In your opinion is there any benefit to doing this? Still learning how to weld aluminum, by the way. Thank you.🙂
Richard Valcourt That does help.
Great video as always, but did I miss something here. I thought he said he was going to lay down some beads on the clean and unclean areas to show what happens.
At the end of the video, Bob said he will soon release part 2 of this video, and it will present the comparative welds. 13:00
Gregory Parrott Ahhh, ok. I was so busy playing back the video looking for the welding I didn't finish the end of the video lol....
Yep i did the same. Until i read this post i was left questioning bobs sanity. Turns out its my sanity that needs looking at.
Nice video,nice tip...
Bob I'm building a auto bodyrotisserie and just wondering what type of welding rod, I've used 6013 in just about all the projects I've built what would you recommend.
Leonard Gilbreath That works well. GMAW is another good one.
After cleaning the different materials, I wanted to watch part 2 on welding over the surfaces but couldn't find it. How do I?
It looks like I need some better abrasives for my angle grinder. I never appreciated just how much cleaniness would improve the welds wtih my everlast.
Resonate - the word you were looking for.
Where do you get your face shield from?
Could you just media/wet blast all kinds of metal clean prior to welding?
lol im welding now for over a year.. new and slightly rusted new steal.. never cleaned my metal.. im going to have e new experiance cleaning it good next time!!
newbie grinder here: can anyone recommend a good flapper wheel for grinding/preparing aluminum for welding? Since I'm trying to grind off the aluminum oxide I'm guessing I don't want to buy an aluminum oxide flap disc? Options seem to be steel and zirconia? 80 grit for welding prep or ...? Thanks!
Stainless steel wire brush by hand. Don't use any power tools, because it will just push the dirt deeper into the aluminum.
what about preparing the surface for you ground connection?
J D Grind it.
maybe discuss hot roll & cold roll steel
Are the fumes generated from grinding rust safe to inhale?
Any stickwelding on weld channel of you only carbon steel, structural. Of you welding. I appreciate your advice and techniques, thanks
I keep an area just for aluminum and one for steel etc.
Gotta say....that 'woo woo woo' comment gave me the giggles.
Is Acetone safe to use to clean metal before welding?
Yes.
Can I use sandblast? Please!
On aluminium, how long do you have before oxides form enough to interfere with your welding?
Almost instantly. The positive side of your AC wave will take care of the oxides.
Weld.com Thanks! Sounds like I need to learn a lot more about what different parts of a waveform are doing to the metal. Any good references out there ?
Excellent video sir! I have learned alot from your vids. Im about ready to pick up my first machine, a 325 EFI Miller Trailblazer. I have offgrid property, and need the generator ability of a gas diven welder.
Do you think it would be bad to use the generator part of a welder 5-6 hours a day?
Refried Beans Good choice.
Can't see it doing any harm, I was looking at a blue star 185 for similar reasons, and we ran a bobcat all day last year at work feeding an air compressor when power was shut off to our work area
Bob Moffatt Well said. Truly the sign of an expert on alternative power generation!
I see no harm. Keep the oil and filters changed and give it ventilation. Don't close it in a small building without good vents. You will be surprised how much heat they put out. People in construction weld with these 6-10hrs a day everyday until they get thousands of hours and they trade it in.
How to clean and prep broken metal table leg?
I'm having problems stick welding thin material (1.0-1.3mm=18-16g) with a cheap DC inverter. Are there some obvious things I should and shouldn't do? I seem to blow through all the time. I've tried 1.6mm (1/16") and 2.4mm (3/32") rods. I try to keep a short arc. I've lowered the amperage to the point of it being almost impossible to strike an arc. I'm going as fast as I can while still getting enough material down to bond two pieces together. I find it really difficult to balance getting a decent weld vs blowing through. Only "solution" I've found so far is to pause every inch or so to let it cool and clean the slag, then resume (very time consuming). And/or make a fast bead on each side of the seam to build material thickness, then make a third weld between them over the actual seam to finally bond the pieces together. Yes, it takes forever. Should I try switching polarity? I'm about to try converting my machine to TIG (as a desperate measure).
I'm using 6013

Definately good idea to convert your machine to TIG if you're going to weld 1.0-1.3 mm steel. I don't think any welder would recommend stick welding thin material like this. But, I think you can try to stick weld that with a little trick, which includes a relatively thick piece of copper (red or yellow) plate to back the plates you want to weld. If the pieces you want to weld together are not flat, this method is not too practrical, because you would have to form the copper plate to fit the backside of the material to weld.
So take a piece of copper plate that is long enough to cover the length you want to weld, it needs to be at least around 1-2 inches wide to dissipate the heat of the welding. The thicker the copper plate is the better, you don't want to use copper foil. Lay the copper on the backside of your future weld bead tight, to let it touch both the pieces with the most surface area. It will cool the steel while you're welding, and will help you to weld evenly. The backside of the weld bead will be smooth, copper won't stick to the weld.
Stick welding anything under 3mm takes a lot of practice. 1mm is going to be really hard. Can you change your design to make it thicker at the weld? Also lap joints are going to work better than butt joints. Hope it all goes well
For steel, have you tried muriatic acid to remove rust and mill scale followed by a baking soda solution to neutralize, then phosphoric acid to create a very thin layer of iron phosphate to prevent rust from reforming?
1:44
Anyone seen (found) part 2?
Scotchbrite is a good way to clean dirty aluminum
Quit piss'n on your aluminum!
Mark Tracy My bad.
if you soak mill scaled metal in vinegar for a few hours the scale will just come right off,
Moshe Galimidi if only we had hours to wait for that..
Vinegar is not efficient and it damage metal.
The screen is black
you can clean it with acid and it will look new and ready to weld.
Busted! Write 25 times with a tig welder on aluminum...."I will unplug my grinder before changing the wheel".Otherwise a good video.Rick
It's not that big of a deal with the grinder. Maybe the electric version, air tools not so much. However, i always disconnect the airline from my drill before changing the bit. That thing will chew your fingers up.
I don't even know how you could TIG for more than a few seconds on anything that isn't super clean.
All that crap floats up, sticks to your tungsten and in no time, you have a worthless sputtering wandering arc.
Yep a problem i often have when i dont prep properly.
Theball Player But folks do it all the time.
Scrolled through the comments to see if anyone was offended by him going "woowoowoowoowoo" about having a "camera-girl". We must be ever-vigilant and always on our toes, to internet shame the internet shamers. 😉
