Welcome to our Channel! We're passionate about providing a comprehensive space where welding enthusiasts of all levels can gather and learn.
THANK YOU SIR. I appreciate the tips! This caught me off guard though, I wasn’t expecting to be mentioned in a video 😂
Glad you got to see it!!!
BRO! The Bob Ross thumbnail had me losing it.......
Haha 😂
Glad to see you putting that metric any size hammer to good use!
lol you know it
Wow Mr Rogers of welding!!!!!!
❤❤
Love your RUclips channel , I’ve learned a ton from watching your instructional videos. Oorah!
Glad you like them!
Thank you!
I have that same adjustable hammer
Hehehe
When you recycled the metal to make new coupons, could you cut the metal with the plasma cutter on angel to create your bevel to save a step?
Cool video 😎 👍
Thanks Darrell
Great video. How about best budget true color helmet ?
What’s a true color helmet? Lol
What do u put the gas on when welding fluxcore
If it were flat wpuld you go around 450 and 25 volts or so?
Nice and pretty uniform, well explained.
I made it in similar way, before more than 26 years, when Dual Shield wires were not under ESAB, and I can see that the weldability is almost the same.
With DS 7100 Ultra , I am very interested to see can you repeat this using 0,052” dia. , and not 0,045”, and which welding parameters should be applied in such a case.
We should defiantly run some bigger wire and try it out!
" I like a good solid bead because nothing can live in hell" lmao.
Haha 🤣 it’s true!
I’m troubled with the Crescent Hammer.. everything else looks good
Why are you troubled?
@@austinhargett5792 I googled Crescent Slag Hammer… zero results 😂
Was the hammer you used Standard Or metric
Left handed
Every tool has a hammer side..
Indeed it does!
I did a wood floor that had to be nailed down. I used whatever was closest to me to knock it in
What was your landing ?
Zero
What kind of HAMMER do you use to loosen a 3/4" nut. You used an adjustable wrench to hammer slag. I'm just wondering what HAMMER you use to loosen nuts.
Maybe if you are trying to TEACH someone something you should use a tool for what it was DESIGNED for.
Stupid me, just a thought.
WHAT?
@@clawabidingcitizenYou CAN NOT be so STUPED as to ask "WHAT?".
Run a D1.1 3G and 4G with NR232 .072" Weld tube hasn't made a detailed video of the wire yet.
I will put in on the list to knock out.
@@Welddotcom the 1" 3G test not the 3/8"
@@Welddotcom There are no videos on RUclips covering the 1". Even hard to find on google.
The hammer you used was the sae/
indeed
Can you do a nr 232 video?
What’s that?! Lol
@@austinhargett5792 self shielding flux core welding just runs so differently than regular flux core welding
Love "nothing can live in hell" lol, made me laugh a little to hard
😂😂
Nice video but the whole BOB ROSS thing is a little creepy dude!
See you in your dreams
I see that backing weld taught often, but in 30 years of working on heavy equipment, 12:10 I have never had an instance to use that weld. Maybe sort of similar welding on bulldozer mold boards, but thats about it. Also, many people will find most any type of MIG easier to run downhill..
This is more for structural iron working than heavy equipment repair
@austinhargett5792 true I guess.... because the backing I am welding is usually already broken...lol.
Dual shield is a flux core soo downhill wouldn’t be recommended. However this type of welding is kinda niche. Stick tig and mig/spray are usually the go to. I believe dual shield is used on some shipyards and they do get a backing strap sometimes ceramic backing straps.
@f.e.oeeorch581 I welded 10,000 pounds of 3/8" thick 3"×4" box tubing and 1/8" sheet metal on a 230 excavator a while back using dual shield, at all angles, out of position, upside down, you name it. I can weld it up or down, but to me, every type of mig I have ever ran does better downhill. You can definitely run it hotter and burn it in better. I have even seen Bob Moffitt say this more than once on this channel, that downhill mig being bad is a myth, and it is just as strong, and he had said that he would argue that its stronger. I have a Forney 270 that will spray, but I have never tried it. I have just never wanted to buy a bottle of gas just to experiment with, although I do plan to try it someday. I guess it's all in how you learn. My dad's best friend when I was growing up owned a pretty big welding shop, and I just learned from those guys. They must have taught me something because I cut timber for 29 years and decided about a year ago that I was going to quit and do something else. Just so happens I had just built my shop on the land I bought beside where I live. It isn't massive, but it has a high ceiling of 18 feet and 14×14' doors and I can house 2 road tractors or 2 big pieces of heavy equipment, say D6 Cat dozer size or some bigger. And now people come and pay me good money to weld. I do heavy-duty mechanics and heavy-duty tires like 800 pound 35.5, 28 ply log skidder tires. But welding has been primarily what I have done for hire.
@@f.e.oeeorch581 I work in a shipyard and we never use a backing strap. Either we use ceramic tape or we just bridge the gap with a weld in the open and fill it up then back gouge it and weld that up too.
I'm picking up a weird Bob Ross vibe off Austin here.
Goooood goooood
Happy little boops ...
The bead up the middle is Temper Bead Welding. :)
not filmier, please explain
@@Welddotcom Temper bead welding is when a subsequent beads' heat is used to refine the course grain region of the previous beads HAZ, the bit right adjacent to the weld metal typically. Those course grains are not very tough, and tend to be the hardest in the weld, i.e. right adjacent to the last cap pass and in the base metal. When you run a bead up the middle like she did that tempers the hardness of the base metal course grains and if you are close enough to the edge of the prior weld but not on the base metal itself it will recrystallise the course grains taking them over 875 Deg C or so but only for a very short time, not long enough for significant growth = a finer tougher microstructure, So grain refinement and a tempering effect. You could argue that the edge [toe] of the center weld is too far away from the prior beads toe where it meets the weld metal to do the very best for it, but it is close enough to temper the hardness in that region in any case.
The reason why the weld metal does not harden as much as the base metal [and thereby suffer from the same hardness problem as what the base metal does] is that the weld metal has a lot less carbon in it, making it somewhat immune [but not completely] to the effects that affect the base metal. For normal Carbon, Silicon, Manganese steels the toughness is what is improved by temper bead welding, for alloy steels it is resistance to hydrogen cracking AND toughness that is improved, sometimes it is possible to drop PWHT if temper bead welding is done correctly, that is how effective it can be - it heat treats the weld as you go. BUT bead placement and heat imputs need to be controlled to achieve a proper result, a result that you cannot see and cannot test for nondestructively, so be careful relying on it unless those controls are in place following a method that has been tried and tested for the particular set of welding parameters you are using.
Blues clues of welding the blippi of the mig gun
I really like your channel man, I’m just wondering when you started sounding so much like Bob Ross. It seems like you’ve strayed away from the funnier stuff, and are going a more “Mr. Roger’s” route.
It’s still great stuff, I’m just wondering why the change? I’ve been watching you for years, and will continue to. Like I said, just wondering.
You’re great either way.
