Weld dot com in the house again before they left Texas now with Abe & Jason welding a 1" plate with a back-gouge. Took a ton of metal to fill up! Hope you find it helpful!
Currently doing this process on a job I’m on. Only thing I do differently. Root. 20.5-21 v 240-255 wire. Cap dual shield. 25-26 340 wire. No manipulation. Stringer all the way out. And this is just from personal experience but weaving on a 2 g is like flirting with disaster as far as trapped slag and getting a case of the good ole worm trails. To each his own. These looked like great welds thought !!! 👍 weld on my friends
This brought back memories. Honestly made me want to get away from the production line scene welding in a gang of handles, Trunnions and repairing other peoples errors. This was really a breath of fresh air.
At our shop we also use the same power unit for our welding as we do for CAC. We use typically 3/8" carbon rod for gouging. Can still pass UT consistently.
On the gouging and messing up a machine. Its true. Run anything at its max for an extended amounts of time tends to mess things up. Welded with many machines that have been used gouging. Still weld fine, as when we gouge its two machines carrying the load instead of one to keep from "burning up" a single machine.
Gracias por los utiles concejos ..hoy fui a hacer un test y creo que lo hice bien, a pesar de no soldar con ese tipo de alambre, gracias a este video, gracias,gracias gracias ....🙂🙂
Would be cool to see some back gouging action on a single or double bevel joint with something like a 1/8"-3/16" landing and showing how to find the fusion line of the root pass.
If I'm running anything that's around 300 or more amps a 12 shade filter is probably a good go-to for taking stress off your eyes, or maybe even a shade 13 to really add comfort in non-critical welding situations where maybe it's easier to see the line you're trying to follow on the joint... This also would probably depend upon if you're hood is auto-darkening or not and if your hood has something similar to 1/1/1/1 clarity.
Yes it is very true... Arc gouging is one of the absabsolute hardest things that you can do to a machine. And your air holes always go to the bottom of your rod...
Abraham: explains why you shouldn’t weld and carbon arc gouge with the same machine. Also Abraham: Gouges with the same machine. Love this video lmfao. Gonna be watching this as I take my 2G tomorrow.
Welding a bit cold with the duel shield to me I hate to be a critic but I never get why people think they have to put a lot of manipulation into welding duel shield as long as you set it right it will runs itself also Arc gouging will destroy the low-voltage range on your machine after time making it hard to run your machine on a lower setting I do like what you guys are doing and the content you put out I was just sharing my opinion
And thank you to the comment section for explaining why the back gouge and refill. Somewhat. So the WPS or work order can require such. I just wonder why from an engineering standpoint. I assume it is a high pressure tank, or very large one, since they are showing this on a 1” coupon ( coopin for Bob). So I should that the only reason? Extra weld material and elimination of a ‘possible’ flaws in the base of the joint? Just curious
Hi guys, here is a "REQUEST", I enjoy your educational input for a 2G. What would really help" VISUALLY "is if you taped some white card to the rear of that joint and used a blue sharpie to simulate the "C" shape and by drawing on both card and plate where you move the arc to if things go out of control.It would make it easier for me,thank you greetings from Scotland .
@@magnatron7734 Pipeline pancake hoods. Basically a pair of cutting goggles wIth shielding attached to protect your face. No slag in your eyes and no glare from the sun in the back of your hood while welding.
Bros can someone please elaborate more on that theory on if you are or aren’t supposed to arc gouge on the same machine you weld on. I’m a newer weld inspector and the shop I’m working at is kind of cheap and buys weld machines as needed and a lot of the welders are only able to have that set up (a machine that they weld and gouge on). Currently a lot of the machines are welding slightly off like the volts will drop or vary between machine and wire feeder. Could that be the issue??!? If so that would make so much sense and solve a lot of my headaches when troubleshooting and getting the welders happy again.
I’m not an expert but maybe it was to do with the heavy duty cycles on welding machine when gauging it requires a lot of amps compared to certain welding processes so maybe gauging frequently puts unwanted stress on the machine we also have that some problem with our machines at we work when they drop volts and amps we let them cool down it helps but it’s not then best solution
When doing it for a welders qualification test, you are having the welder demonstrate the ability to perform the arc gouging process. I'd rather find out in a lab setting that someone didn't have the ability to perform the necessary task...
Those 350s gouge all day long there designed for it and have a gouging mode thats key if the machine your using has a CAG mode i have the everlast mts 400 its a beast its there most industrial machine and has a mode as well
Due to them welding the root pass of the open root joint properly with what looked to be good fusion, gouging the far side wouldn't have been necessarily needed unless the welding symbol/blueprint for a job called for a back gouge but as they said they used the gouge on the far side for instructional purposes... But anyways, the gouge is supposed to remove the fusion line from the initial root pass on the near side (bevel side) of the joint so that when you go to weld your root and fill passes on the far side (back gouge side) proper Complete Joint Penetration (CJP) is achieved. Without using the gouge the weldment could crack or tear under stress along the fusion line or if your initial root pass maybe had discontinuities or lack of fusion you would never know without back gouging until it came time for a bend test or NDT (non-destructive testing). Complete Joint Penetration isn't always necessary as I said before... Sometimes they only want Partial Joint Penetration (PJP) where you would only fill up the beveled side and call it good and they would maybe do a Magnetic Particle Test to insure there's no surface discontinuities. They will typically do a PJP where perhaps the stress on the weldment is not as high or as critical, as say would a Complete Joint Penetration weldment for a column base plate would be for example. Hope this clears things up.
Back gouging is cleaning out whatever was trapped in the root, slag porosity, pin holes ,or infused plate edge that shows up on a ut,or rt. Once gouged u weld it back up nice and clean. Basic process how we processed shellplate
I have seen guys fired because they could not gauge correctly or cleanly. You gouge too deep, you're gonna spend a lot of time filling it back up. Its a needed skill in the welding world.
Damn i am getting confused. Seeing all these video's. I learned that MIG was for aluminium. Meaning. M=METAL I=Inactive G=GAS. and welding steel is MAG. M=METAL A=ACTIVE G=GAS. am I totally wrong? I'm from Denmark so maybe it is not the same way we describe the method by letters. My point being. Aluminium uses pure argon. A gas that only shields the puddle and interfering. And steel uses argon co2. Co2 being a gas that interferes with puddle causing it be hotter and creates a stronger weld. Am I totally wrong?? Greetings from denmark.
inactive gas means its has no efect for the actual weld, just defend it from the oxigen (argon, helium etc) Active gas is make an interaction with the welded metal (co2 for example) the carbon (from carbon dioxide gas) transports to the metal and make it stronger. if you mix argon with co2 its still an active gas
you on point, because Aluminum does not need carbon at all, only anti-oxigen surface for defend it. Thats why always people speak about mig welding aluminum
@@peterbagosi3862 yes BUT in video they say that use the MIG welder. But is it still when I dual shield wire?? Almost every video refers to MIG welding no matter if it is steel or aluminium. That's why I'm confused.
Mig is a popular name of that type of welding, like TIG or MMA, I or A only means the gas. u CAN use MIG welding for aluminum, stainless and steel as well, u just only need to replace gas and filler material (wire) and ready to go ;) sometimes its dificult to MIG aluminum because its need AC instead of DC and ur machine must have pulse function
@@peterbagosi3862 aluminum mig is a DC process and you don't need pulse. A spool gun on any mig machine with pure argon, tri mix, or helium and you can weld aluminum. A push pull machine with pulse is a lot nicer to weld with.
