This man is an excellent welder! If you are really wanting more of the science behind why what he is doing works please open up and read more on my comments. I have been welding for 15 years plus. I just want to pass along some of what I have been taugh and some of what I'v learned the hard way. But with as skilled as he is I am sure he would agree I am just passing along rock solid proven practices.
Just got my AWS D1.5 certs thanks to these videos and lots of practice. As a gift to myself i bought a Miller 211 Auto-set 110/240 mig welder. Thanks Miller!
+Dminkov Zaitsili Congratulations! We're happy to hear that. Great work and weld on...
thanks for uploading this process. Now I know to have my line of sight above the weld . I had my line of sight level with the tip in front of me. Nice to see the use of the zig zag too with little or no pause on first two passes and final pass had a pause on the sides. My mig welds were lousy, but now should improve.
perfect settings!! makes all the difference
Cool! First time see such beautiful 3G welding. 100% thumbs up. Please show us more in other positions.
I want to see the actual bending,face bend,root bend and side bend.but it is an awesome weld,good hand manipulation,thanks for the video it's very clear.
With this prep and fit-up (3/8" mild steel plates, 37.5 degree bevels (75 degree included angle), 3/32" gap and land), these are my approximate settings. Just know that it may vary depending on the welder and welding machine, but this should at least get you in the ballpark so-to-speak. Using 30-35 cfh C25 gas and .035" ER70S-6 wire. Keep a short wire stickout of no more than about 1/2" throughout each pass. Preferably 1/4"-1/2" stickout.
Root pass: 17.3-17.5 V and 240-250 ipm WFS (slight weave side-to-side at front edge of puddle is necessary if your gap is a little on the wider side of 3/32" or close to 1/8", but if it's a tight 3/32" you should not need to weave as seen in this video rather shoot the wire straight into the gap and work your way up on the front edge of the puddle). Filler pass: 18.0 V and 220-240 ipm WFS. Cap pass: 18.0 V and 220-240 ipm WFS. Keep in mind that it's usually always better to run your passes with as much WFS (hotter weld) as you can control because it will usually correlate to a more successful guided bend test.
looking at the table for Miller 255 and reading the info. It says 3/8" C25 .035" wire - 22.3V and 442 IPM DCEP. I am a rookie , so maybe next time I try your settings. I was getting a lousy weld using their settings
Could you provide the Voltage and Wire Speed settings for all three passes?
I noticed a slight side to side motion for the root pass, never thought to try that...
These videos are very helpful in that you can really see what the tip of the electrode is doing. Thanks a bunch guys!
congratulations, so good
great work.
Very nice job, Bravo! nice even weld great penetration on the root and very nice even cap with no sag or undercut! People should pay close attention your settings for this weld were great! Your puddle was just the right fluidity. It froze up enough to not run out but still followed you enough to prevent undercut. Diffrent machines on diffrent power makes posting exact settings he used not practical. Watch the video and look for what I pionted out in his welds and yours. 50% of quality from mig welds comes from properly setting the welder.
hola, queria agradecerte y felicitarlos por el video, muy bien editado y queria hacerte una pregunta, a cuantos voltios y ampers estan soldando.....
excelent welding.
If you're using a pipe works 400 series these are the settings I use,
Root 16-16.5v WS175 arc control 15-25%
F/C passes, 17.5~v 165WS arc control at 30-50% for a flatter more washed cap.
Thats what works for sst on that with co2 I find. But my lincoln is way different
Please clarfiy, are you asking, "Is that a MIG machine?" or "What MIG machine is used?" Or are looking for more of these beyond the MIG process?
When first welding uphill with a mig rember you are using DC. DC creates more arc blow if at all possible put your ground where you are moving toward your ground, that will minimize arc blow. Clean the area you are going to ground at just as well as the weld joint mig welders don't care if the ground breaks up they just keep pushing wire! Often times only about a 10-15% reduction in heat is all you need as compared to flat for out of position mig work. Setting the welder to cold and not traveling fast enough can cause heat build up. You are rising up the joint and so is the heat. This is often indicated by the first inch or 2 looking pretty good then the weld becomes hard to control and problems with sag and under cut start happening! Hope I have helped someone have a nice day.
I am learning mig welding. I never considered grinding down the area where the ground goes. Good to know
good job
Helal olsun hakini verdi
Can you do a video of setup and weld of a 6gr weld groove test
Super 👌
T'nkyou❤️❤️❤️
Muy bueno es mi oficio
Oneday he is a legend.
voltage , wire speed ?
galing grave///
What your voltage and wirespeed on the root, pass and cap
அருமை
Is the weave technique demonstrated here used with fluxcore as well?
what is a good setting or settings used in this video
Did u walk the cup or nozzle for the root pass? I rewind and rewind and rewind but really not sure on my guess.
Parabéns
look neat
That was a sexy cover pass
Luar biasa anda jago,,👌👌👌👌👍👍👍👍
Been trying to learn this, just can't get the setting right. Any tips on the settings? My machine doesn't have digi
Hi I am looking for some videos mainly flux core..either core eight or something like a 232 looking for vertical test root pass
His beads look great, but I bet he goes through lenses like crazy with how close he is to his work
could you do a vertical up video with innershield please? i went to a shipyard to do a vertical v groove with back plate test and failed badly :( i think i might have gone too fast or maybe my stickout was wrong.i did something wrong. my welds came out looking like long caterpillars.
Nice wilder'
That root pass was ropey but that cover pass was a stack of dimes. Nice.
Stephanie Lisenby YES!!! GIRLS IN WELDING!!
What does a woman know about welding? Maybe you should leave welding up to men maybe you're good at baking cakes....
You're smoking hot wow! If you weld as well you're a dream come true lol
Ola aquí en México donde se puede tomar un curso en este proceso y q espesor tiene la placa?
Hi, I wanted to ask politely if you can show me what the position of the body and hands to have a good stability, or if you use supports or if it's completely free hand to get a good weld. thank you
Von Mozz The most important factor is to be physically comfortable in order to produce consistent welds. Exact position differs based on keeping stabilized and comfortable, but we recommend keeping elbows close to your body and taking advantage of what's nearby to lean against for added stability. Every welding situation requires different measures.
What better welding up hill or down hill
How many ampere & speedwire rootpass , 2ndpass & caping ?
is this MIG or flux core? what are the settings ?
I've been told 16.5 and 170 for heat and speed.
Thats it MIG Mechine?
3G single V groove weld, for a straight mig weld on plate?
What cert is this for?
All structural welds I've ever done are in the 3G-F position w/2 stop starts
Thanks for your question! The Specification Sheet from the manufacturer of the filler metal you use is the best tool to determine starting welding parameters. This video was developed to illustrate a weld and the specific welding techniques and weld settings used are not necessarily the best for all applications. We intentionally left the weld settings out of this video because following any local, state, or national codes or standards is the responsibility of the welding organization producing the weldment. Testing the weldment will ensure that the settings, technique, and overall procedure that you develop will meet the requirements of any applicable codes or standards. Please let us know if you have any further questions. Thank you!
Same mate. The inspector always wanted to see a stop start in the middle of the plate.
Если бы еще указывали напряжение и подачу для корня и перекрытий, это самое главное ...
amperage and voltage one size or changed
There is porosity in the cover pass
there is some all the way to the right two little holes right next to each other
what were the settings this welder used for his root pass? also what was the root opening and knife edge or a slight land?

umm ok just was curious because I run mine at a certain voltage and wfs that works for me but was curious what he ran his at for his root and what his fit up consisted of
Obviously it’s different for everyone ... but there is a clear range. Glad other people actually answered the question. Lame

Hello, it is possible to weld the root pass downhill of vertical seams ?
+Евгений Гусев You can weld any way you like as long as your welding can meet or exceed any applicable local, state, or national codes, specifications or standards.

Everyone does stuff differently
Wich wire u using..i mean 1.2? 0.8?

Why don’t you just give people a range? Actual numbers for voltage and wire speed. And no the spec sheet from the wire manufacturer does not give these numbers. That’s just incorrect.
What settings did you have it on?

GMAW?
Hi Rian, this video shows the GMAW process.
Everything was listed but the dimensions of the root opening and the root face (land). There is no way that was an 1/8 root opening and a knife edge.

As a Certified welder in the ASME , API, and AWS codes for over 40 years in the nuclear, refinery, aerospace and oilfields and also as an AWS-QC1-CWI ( certified welding inspector) I will state that after every pass as viewed in this presentation using the flux core process - the bottom "overlapping" weld ( known as cold lap) must be ground down to parent metal. Otherwise when x-rayed the weld will fail. The flux core process is a filler process and has virtually zero ability to burn out lack of fusion. The metal must be very clean; and every pass have the 6:00 position ground to eliminate slag lines. The overall appearance of the finished "cap" is not symmetrical throughout the weld from start to finish. Also, the "cap is to high which means to much metal which creates stress pull upon the weld zone - thus weakening the weld. The welding process was excellent but the end result was not. The weld width must be the same width throughout the weld zone.

Still wouldnt hurt to post the volatage and wfs, awesome video though
FACTS!!!!
+Aaron Spoehr TRUE!!!!
mai Ronamcㅡㅡ
Weaving will get you fired every where I have worked it makes under cut in it traps slag
Are you sure about that?
GMAW has no slag...
So where was the undercut in the video?
Weaving is not the right way to do this.... yea it may work but you'll get undercut everytime... you can see it in this video even
for people who want good volts to wire speed using 1/16 flux or dual shield use a volts of 24.6 and wire speed of 315 to 335... tune to your speed
Undercut is eliminated by a slight pause on each side of the weave pattern. I also recommend a slight rainbow shape to the weave pattern. I avoid undercut that way...
....tal display.
Please tell me.
Model of machine used?
Voltage setting?
Wire speed?
How is his liquid metal not running, if I was moving at that speed I'd be making steel tits!
