Short Circuit MIG vs Spray Welding Bend Test

Short Circuit MIG is generally used on thin materials due to it's prone to lack of fusion. Today we are going to put that theory to the test with a welding bend test. We're going to run a short circuit plate, as well as a plate with spray transfer and compare the bend test on both.

Anyone who is looking to actually make the short circuit work, some things I believe Red Beard could have touched on: he could have had much better luck on his short-circuit root if he had of stayed on the leading edge of the puddle jumping from corner to corner a bit faster instead of staying in the middle and allowing it to slowly fill the space up. If grinding is allowed, he could have also knocked down the convexity of the root a bit so the hot pass would have better success to to further melt the root corners in better. Thanks for the Video.

I still remember going into a fab shop to check on a vessel they were building in the early 90's. They were putting the can sections together and all I could hear was "putt, putt, sizzle, putt, putt." coming from both welders. I double checked the weld procedure, took a short video on my old sony mavica camera and talked to the foreman. I asked him "what process are you using short circuit, globular or spray transfer" he looked at me like a cow at a new gate and said "mig, you idiot". I asked to use the phone and called the client. fifteen minutes later the owner showed up and shut the job down for a client visit. After another hour of light snooping I found enough other issues that the client rejected the vessel outright. they ended up cutting the pieces up for scrap. Heads, can sections, nozzles all had issues. I submitted my report and hit the road. The man rep later called me to say they scrapped the original plan and went back to submergerd arc and GTAW construction with a different material of construction. I guess that turned out alright because I never got the call to court, haha. That was the first vessel I condemned, boy was I nervous!

We run short circuit for everything, and have for over 25 years. Machines are Lincoln CV305 power units running 460v 3 phase, typical settings are 25-27v 450-525w/s with .040 er70s-6 wire running stargon (Argon/carbon dioxide/oxygen mix). Never had a problem, and routinely have stuff sent out for destruction testing (have 1" diameter d-rings come back shaped like footballs with zero weld fails on the clips). The gas we use does allow for spray transfer, but we're required to do a lot of overhead and vertical welding.

Interesting. I'm a hack at this. A much better grinder than welder. But when I do weld, I make sure to direct the wire into the corners with a combination of gun angle and side to side motion. It just seemed to me that you were relying solely on the puddle to fuse into the base metal instead of using the arc force to punch the heat a little deeper. Am I off in left field here? Also, I'd like to see this done with both gasless and shielded flux core.

@login9804 4 жыл бұрын

I would like to see this test in a less controlled application like you are saying by angling the gun into the corners instead of just relying on the puddle. Seems like it would have a better chance at passing that way.

Corner cracks are pretty forgiving, however, don't forget that the examiner will always be checking that corner crack for signs of lack of fusion or slag inclusions, or other discontinuities that can be attributed to the welder. obviously depending on process.

@gmacka6333 24 күн бұрын

I find the best trick to passing a mig short circuit Bend test, keep your wire feed speed fairly low and manageable. A good rule of thumb is the 10/1 ratio. So if you're welding at 18 volts, turn your wire to 180 ipm.

@ShadeAkeley 4 жыл бұрын

@phillhuddleston9445 3 жыл бұрын

So as long as you have enough amperage, voltage and wire speed and you use 95% argon/5% co2 gas you can spray weld is this correct? The reason I ask is I have a dimension 652 welder that is transformer based with a 400 amp torch so there is more than enough power but I wasn't sure if you needed an inverter based welder to spray-weld.

@shexdensmore 4 жыл бұрын

95/5 does not increase the heat transfer. It does the opposite. You need 80% or more Argon gas mix to create a spray transfer. It's the argon combined with the higher current and most of all, the higher voltage (I forget what the required voltage and wire feed is) that allows the process to be a spray transfer. Giving it a deeper penetration. The increase of Argon increases the pinch force causing molten droplets to form at the tip of the wire. I'd love to see a short circuit welding of this metal thickness done with 100% co2 gas shielding.

I have been welding for 20 years hold 30 plus certs. I have short circuit welded .0.35 75/25 co2 argon for years on heavy material never had an issue. You welded that short circuit at ridiculous low settings especially for flat and back up strip. Of course it broke if you ran normal setting. 0.35 24v 350 to 385 it would have passed no problem. All of my mig tests were done short circuit. Your spray was set high voltage it should pass. I welded at caterpillar for years and was welding 1.5 in thick steel short circuit. All welds ultrasound inspected never failed one weld. All in the settings.

Dean Rosner true Dean, it can be done,I’ve done it too. The trouble is it takes a combination of perfect settings and near perfect technique _ consistently. He mentioned”repeatability “, that’s the issue. It’s not common enough for all of the needed things to come together every time. A focused welder ,who knows how to set the machine for thickness/position/purpose/environment who can read every shift of the puddle split second by split second. It’s just like common sense- it’s not as common as it should be and therefore can’t be used as a standard safely. - neither can short circuit welding on structural.

@xblizbroke 4 жыл бұрын

@@deanrosner2007 at 24v with 350ish WFS you'd be getting closer to spray transfer with higher argon content though. You also claim that globular transfer and spray are achieved by turning down the wire speed and that you must turn down the WFS to go from globular to spray? Spray: high current and WFS (220A+) in argon rich shield gas - high deposition, smooth, clean bead with very little spatter Cons: not good for thin material or out of position welding (unless it's a pulsed process) Globular: operates between the upper amp limit of short circuit to around 400A providing high deposition in flat position using CO2 rich shield gas and thicker wire Cons: poor arc continuity, excessive spatter, needs gravity to deposit droplets The processes aren't just turning your wirespeed down or up and short circuit is the lowest current/deposition rate method of the 3. Electrode size, gas content, weld current, and arc voltage are what makes them different and achieve the following characteristics- Short circuit: electrode contacts workpiece or weld puddle many times per second to transfer current which forms a short circuit (hence the name) melting the workpiece and electrode Spray: arc established through inert gas from electrode to workpiece, melting electrode and workpiece while magnetic forces from current pull the filler metal into the weld puddle Globular: arc established from electrode to workpiece through shield gas melting electrode until a droplet forms and grows large enough for gravity to pull it into the weld puddle.

Short circuit, globular, & spray are "modes of transfer". Those words are welding terminology that describes how the metal is being deposited (aka transferred) from the wire to the base metal being welded. In the order I listed them, generally speaking they go from "coldest" to "hottest". How you as a weldor obtain those modes of transfer has to do with both WFS and Voltage. It's not a "button" on a menu somewhere. You can do more research on your own from Google, but basically your latter description is correct.

Love spray high voltage, fast wire speed, sexy weld and grate penetration overall better imo

Jason, did you mention what size wire you used ? hope they were the same. I would like to see spray verses dual shield ,same size wire. I started using Esab 7100 Ultra dual shield after seeing Jody Collier using it with JD, that wire is exceptional and any position. wire so I wonder how it would stack up against spray mig as you can use the same 75/25 mix as regular short arc mig so you don't have to buy another gas which is also more expensive than 75/25. So now on anything over 3/16 I use dual shield and under short arc mig.. You tests are great keep up the good work.

Tensile properties with Dual Shield 7100 Ultra should be higher

@bruced1429 4 жыл бұрын

@@fehu-soldadura the 7100 has a yield strength of 78 KSI and tensile of 88 KSI with 75/25 which is more than 7018 rods so plenty of strength in the 7100. this info I got from ESAB"S materials pdf.

When I worked at Cat we ran spray transfer 75/25 argon/Co2 with .045 Lincoln L-98 wire it gives very consistent welds for flat and horizontal welds.

Stupid question... Can you use spray welding to fill/weld a cast iron part? Great video

@deanrosner2007 4 жыл бұрын

Not cast. Cast is really finicky shit sometimes it works sometimes it dont. Try silicon bronze tig. works well for hard to weld parts. Or stick weld remember pre heat and keep the part hot during passes and try to cool as slow as possible. Good luck

Apologies if this is a dumb question. Can a Millermatic 210 be used for spray transfer? The machine says it's rated for 3/8" single pass but I have only ever done sheet metal / body work, never any structural welding so have only done short circuit MIG.

@sigsauer2557 4 жыл бұрын

You really need 26 volts or higher on a mig and a minimum 90% argon.

@marklugo6002 4 жыл бұрын

It depends upon the wire diameter really. Yes you can, but no you probably don't want to depend upon it for daily use.

@18JamesBlond 4 жыл бұрын

spray transfer is all about your settings and gas. start by changing you gas to 90/10 or 95/5 argon co2 cranking it to 24v and 350 wfs and tune it from there.

@Sicktrickintuner 4 жыл бұрын

You can, but need proper gas, and would most likely max out the duty cycle on it quickly

@TigerNash21 Жыл бұрын

Have you ever considered just turning up your heat when using short circuit? Especially in the flat position, there is nothing stopping you from running that weld at 23-25v and a matching wire speed

That does quite sound like short circut, but more of a spray

I mostly spray arc at work and I like running .045 wire at 27.5v and 375wfs with 90/10 gas. When my machine was new I could run it all day at those settings but now after about a year with the machine, I can maybe run 2’ total of weld before it starts sputtering and will then ruin the contact tip. I feel like I’ve kept good care of it and replaced consumables as needed. Any idea what could cause this? Thanks

ground clamp/wire? stinger liner? Oh yah, is the metal clean? Mig/Tig doesn't like scale or rust or oil.

@@fewtoes I'm no pro welder, but I've had a Miller 185 for 20 years and it started acting up on me. Replaced the liner. Back to normal. Then it started acting up again, so I purchased a new welder. While doing some comparison welds I noticed that the nut that holds the wire onto the ground clamp was lose. Tighten that up, back to perfect welds.

@Sicktrickintuner 4 жыл бұрын

You have a shitty connection somewhere. Just fixed one I bought off a guy, it would stick all the time, The gas orafice was toast, so bell mouthed on the contact tip threads it was always loose. Was also missing the set screw to hold the gun liner.

Greg9504 Yep i had the factory ground clamp burn up on me. 211A machine and only 6 ga ground cable. When it should have been min 4 or at least 2 ga. Only found the issue when I smelled the rubber at the clamp end wire melting. It also melted the ground clamp bolt that held it on.

Thanks for the replies. I roll the machine all around the very bumpy shop floor everyday so that would make sense that a connection has gotten a little loose. I’ll have to check when I go back in
