As a hobby type of welder, I still just run wire to practice and it is so helpful to see your patterns and also what you look at as you are welding. Thanks for the great tips.
I've gotten so much better at welding after watching these videos. I haven't done much uphill welding with my everlast mig welder so this has been very educational.
I was given this channel by the man who is teaching me to weld, well to prepare for welding school. I have learned a great deal from this channel, I don't know how you trolls can give him one thumb down?
I'm sure Jody will never see this comment but I am eternally grateful for his content because watching these videos very much helped me land a welding job at a shipyard, which I am loving. Thanks! :)
Welding is a art I build Rocky mountainare trains I’ve been welding over 9 Years now and I still learn new techniques I love my career thanks for the tips bud
Love the cut and etch videos. I think about videos like these whenever I weld with solid wire. A guy can get lazy and just burn it in. But, when you do the tests a simple modification to your procedure can make a difference.
Nice too see one of these done again. The last uphill outside corner joint with MIG i ever did was back in my training day´s 20 years ago at a submarine yard. Some way somehow since then i just never came across it again. Thanks.
I've learned tig this year and next year I want to learn Mig, so your video helps to give me some idea what I'm getting into. Thanks I enjoy your videos.
Jody, A good follow up video to this would be a bend test and cut/etch comparing two different open root welds. One like you did here (open root downhill with an uphill cap), and test it against a downhill open root, downhill cap. I think it's a common misconception that downhill welds are weaker than uphill. Both can be nice and strong if done properly, and you're the guy to prove it. Another thing that might be worth trying is a bend test on that metal (with no weld) to see if you can purposely get it to split on the possible lamination.
Maybe the reason a lot of people think downhill welds arent as strong is that you dont get much penetration depth compared to other positions unless you get voltage/wirespeed/inductance settings, lead angle and travel speed pretty much spot on.
I love your technique! I’m using the same method at my welding shop and it turn out great. My coworkers will ask me & I direct them to your channel. So, thank you!!
Since I started watching your videos I've done a lot of cut and etch before anything structural, I believe I've become a much better welder by fine tuning my skills. I've only seen delamination twice, once on 1/4" and once on 3/8" plate, when I brought the 3/8" back to the steel supplier and showed him he told me it's not a problem! After a good argument I got my money back and haven't returned.
If you change from a weaveing pattern to a step and drag motion and allow the puddle to bleed over the edge you can eliminate the undercut and achieve max penitration in the joint while at the same time getting that crisp clean stacked look
I've encountered lamination while tigging 2" stainless. Clients really appreciated the discovery and had traceability look into the matter. Defective material can be dangerous for end-user. Watch your work carefully. Great video! Glad you caught that and pointed it out.
theyre not even people, im sitting here home from work. just thinking to myself, damn jody is a good effin welder. just turned 30 no where near my potential in my career. going back to school soon so i can train like this guy.
I don't understand people who get their jollies by shooting down folks videos and work. I figure they're eaten up With Envy and here they can hide behind their computer screen and say things they would never say to someone's face. What a waste they are to society....
matt matterson if you know how to weld, In my opinion don’t go to school to further your skill... take that few thousand and buy material and practice every day after work for a few hours. That’s all the school is, you pay so you show up. If you have no welding ability then school might be an option because simple things like “strike an arc” “dcep or dcen” “what tungsten” should be know by all welders.
Jimmy Bare I agree for the most par, good example is I watched another “welders” channel and he “made” a hammer as opposed to just buying the right one for $100. I didn’t comment on the video but cmon... you can’t tell me the material was just shy of $50 and the 2-3 hours wasted. You only make tools when there needed on the spot. I worked with a Cnc/manual machinist/welder and he always said if you can buy it they can most likely make it faster and cheaper than me.
About that straight line... one time while getting a brand new school but ready for its initial state patrol safety inspection I noticed a small tag(steel) comming from the middle of a 8” X 6” X 3/8” X 6’ long power train subframe channel. I pulled it trying to break it off and instead it gave way slightly. I regrabbed it w/ a pair of vice grips and it gave way further, growing wider and deeper. Using a pry bar under the vice grips I gave it a really good pull. It was now almost an inch wide and about 5/16” deep. The bus was not put into service until the subframe was replaced.
The first weld looks like it has a stress concentrator in the root. Even worse than incomplete penetration is a sharp cornered crack like that. It focuses stress at the tip of the crack to open it up further.
I remember doing things like this in school. I took welding classes for 6 years and have been certified twice. But at the time I couldn't get a job because I wasn't insurable and I didn't have on the job experience...... but I can't get on job experience without getting a job. Hahaha
There are too many videos to comment individually. First, Jody, thanks for making the time to share your knowledge and experience. I can testify that my TIG welding is 100% better than it was just two weeks ago after listening, watching, and re-watching. It's not just one thing or one video, but repetition and practice. Watch a little, weld a little, think about it, rinse-repeat. So, thanks for your time and effort. Second, I bought a tig-finger anyway, just because it works. Question -- I didn't seem to find a video on this topic: choosing gas for TIG. He, Ar, or mix of the two? Pro and Con for going He vs Ar? Thanks.
My understanding is helium is mostly for better penetration on thick aluminum. Jody has a few videos that address it - just search his channel for helium.
pure4life0wn I would not even put it in the same class. Never seen any grinder stand against a Metabo for size, durability, smooth running, power. The Makita is only 9 amps. The Metabo (comparing the 5" since you threw out the 9005b) is 14.5 amps. 2 second brake, auto balancer. etc...I buy the "quick version" (quick change nut for swapping disks) Amazon offers a 4 year warranty for like $30 never had to warranty one yet, they just never get returned.
Makita's are great, but i recommend Metabo for high production work. They're German made and ultra durable, also like Tim said they got the amps for heavy material. The locking nut design is outstanding as it never fully locks hence no need for a key (unlike some quick release designs) and the auto balancing really does help if using it for sheet when finishing a product. Allround the grinder is worth the coin and are the only grinders in the shop that never really need servicing besides if someone damages the power cord ect. I will say Makita's are a close second though, they're are a pretty solid grinder other then the overall trigger design that personally i have never really liked.
Somebody worked out one fundamental secret to youtube technical videos. Don't say a single word or show a single piece of film that isn't necessary. The remaining ten million uploaders, please take note!
Do you think the lamination contributed to the undercut...maybe overheating acting like a thinner metal? Also, why compare 1/4" no gap to 1/8 with gap? Not quite apples to apples. I'm not picking, just curious.
hey Jody i'm a french welder, i've learn everytrhing about welding because of you, and i have a suggestion for you if possible, i can't understand all you tell in your podcast, and for me i lost a huge ton of informations about welding can you see to translate your podcast with subtitles in french or other languages ? thanks in advance fr answering me
my dad been busting my balls ever since i got a my card for welding & high pressure classification ... that u cannot mig downhill and uphill ... jokes on him ... ;) thx joddy ...
If one has a base type miller 350 power supply with an added miller wire feeder with no voltage adjust and no digital readout dc output at a constant 24.7 volts, how would one calculate the amp ratings and wire speed for .035 solid wire on a given thickness of hot rolled carbon steel outside of trial and error?
Useful video, as always. I'd almost be willing to bet that undercut was down to gun angle. It looks like your were pointed toward the right side a bit, which will usually lead to undercut on the left side of an outside corner joint. I say almost because it's hard to tell gun angle sometimes, even when you're the one holding the dang thing.
Can we do this etching? What's the liquid? Some kind of acid? I googled it a bit and it seems to be quite a hassle - you can't just cut and etch, we apparently have to polish down to about 800grit. Takes a bit of doing. But maybe those hits were all out of date now. This 'tweaking' of current and wire feed leaves me out. I'm just an amateur DIY and my machine has only four current settings, there's no tweaking there, and the wire feed has infinite control but no readout so you don't know what you're doing. And actually I finish up using it just about always on minimum setting for after that it just races away... Does that mean with machines like that we can never really hope to do top MIG welding?
GREAT VID JODI, AS ALWAYS BUT... REGARDLESS OF WHATEVER PROCESS I GO THROUGH DURING ANY PROJECT OR PROCEDURE TO ME, SAFETY IS ALWAYS, ALWAYS, ALWAYS "THE NUMBER ONE PRIORITY, LAW AND RULE". I'VE NOTICED THAT EVERY TIME YOU BRING A GRINDER OR AND SPECIALLY A CUTTING WHEEL, THE ANGLE HANDLE IS NEVER TO BE FOUND ON THE GRINDER! COMMON SENSE SAYS THAT USING A GRINDER WITHOUT A 90 DEGREE HANDLE, ITS LIKE "TRYING TO GET CONTROL" OF A LIVE AND ANGRY SNAKE BY HOLDING IT BY ITS TALE AND HAVING NO CONTROL OF THE HEAD!! I USED TO HANDLE MY GRINDER LIKE MANY PEOPLE STILL DO, WITHOUT THE "GRIP-HANDLE" AND TIME AND TIME HAS PROVEN ME WRONG BY THE CUTS AND SCAR MARKS (ALONG WITH BONE GROWTH FROM DEEP CUTS RIGHT THROUGH MY GLOVE) THAT I'VE SUSTAINED OVER THE YEARS. I'VE LEARNED MY LESSON AND THE PROPER WAY TO HOLD A GRINDER WITH FULL CONTROL. ALSO, NO MATTER WHAT ANYONE SAYS, MY GRINDING TECHNIQUE HAS IMPROVED BY SIMPLY USING THE HANDLE ALL THE TIME. PLEASE MAKE A NOTE OF THIS IN ANY VIDEO WHERE A GRINDER COMES INTO PLAY, AND BE SAFE JODI, ALWAYS USE ONE. IF IT DIDN'T MATTER, THE MANUFACTURER WOULD HAVE NOT PUT IT THERE. THANKS
I noticed u still using the fabricator252i in ur mig basics videos u said it was going back like it was on loan or something, did u keep, buy or did it get given to u. I got the esab fabricator 252i wich I love , same machine different bage but the rare 3in1 that runs 6010 great
I'm guessing crappy Chinese steel. On the other end of the spectrum, the Metabo grinder I've got is one of the best designed grinders I've ever seen. I actually look forward to using it.
What's with the lamination?does that mean it weekend the metal?weld was too hot?I hope I can start welding soon.would like too learn.thanks for the info
I think it's good in the sense of education to show the vertical corner. But for the sake of practicality I would run downhill. I dont know about you, but I have never ran into a situation where I was specifically required to run vertical on a corner joint like that. But, good to master..
I rarely use my MIG so I do not have settings just memorized. I use the Lincoln Electric parameters app which has a button for GMAW but does not specify short circuit, pulsed, spray transfer or other options. The settings always seem very high for me, I am getting better at guessing how much to turn the machine down so I do not need as many test pieces as when I started. I ran 1/4" mild steel, 0.035" wire and 75/25 gas and the Lincoln app comes up with 375 in / min wire feed speed and 22.0 volts. Then I see you using half the speed and four to five volts less and the welds look like a much more controllable speed than I use even turning down my settings from the app recommendations. Any chance you can do a video comparing the Lincoln app settings with...uh... reality? And if you get really carried away, the difference between short circuit and pulsed GMAW on a Power MIG 350 MP?
I recently noticed at Lowes that they had a Lennox brand diamond impregnated cut off disc to use in place of the normal fiber cut-off discs with your angle grinders. They were around $15 each. I was wondering if you knew if these worth a dam in comparison to the fiber cut-off discs? do you get your money's worth out of them?
I heard using a tool that creates heat ie the grinder, plasma or gas cutting a sample piece will distort and mess with the grain structure of the weld nugget, is this true?
Jody id like to get ur opinion on the fabricator 252i ibought the esab wrapped fabricator 252i and like it ive used ur setings ive seen in ur mig vids when u use the 252. Do u have it set on manual or auto arc settings
JodyGreat video again. Question. Do you have any videos mig welding 16 or 18 gauge steel tubing? I'm new to mig welding and trying to learn as much as possible.
I will definitely try that today. Currently one weld i have to perform multiple times a day is an overhead outside corner 1/4 plate to square tube steel, 045 w/gas, with a
There are lots of places where the inside needs to be smooth & square (making a sleeve for square stock). How can one get near total penetration and still have a smooth joint? And not weld to the stock inside if you have used it as a form ( with a shim).
Great videos, as always. I did notice that you tend to not hold as long on the left side of your weave as you do on the right. It also appeared from the camera angle that you didn't wash over as far to the left. I wonder if that is part of the reason you only undercut on the one side.
I am having some real issues with uphill mig. Can anyone recommend some good basic settings (volts, feed, wire size,) to attempt it with. Also what thickness metal should I be using for this kind of weld? Thanks
The sharp inside corner could be the beginning of a possible future (fatal) crack because the cornermight be to sharp. Just like a sharp corner on the key of a marine shaft: ie Keith Fenner takes out these corner just to prevent a start of a possible future failure.
Great vid. As always. But I'm confused. The line of delamination was in metal when made or you caused it welding? I'm still learning to weld by your good graces of sharing your knowledge. Thank you.
