Why are my tig welds GRAY? (It's not what you think...)
One of the most ANNOYING problems I help people with, is working out why their tig welds are turning out GRAY! This is something I dealt with, and had to figure out the hard way, so my goal is to help you work this out FASTER, and show you that the problem may not actually be what you think it might...

Hey I’m new to tig welding and have only been learning through KZread, I’ve been practicing on regular steel plates and I’ve gotten better at keeping the tungsten at a good height and not touching the filler rod with the tungsten but the tungsten is still getting dull really fast and not staying sharp at all, what would cause that?

Dang. Been tig welding for 40 years and uh… well… I learned something. Thanks man. You just got a new subscription.
When it gets really bad, I've heard it called "sugaring". Another name the lab coats use is "carbide precipitation". It is basically removing all the good compounds that make stainless stainless. You will eventually get rust in the effected areas. The man is right --too much heat.
@FullCircleTravis

You're correct, the proper name is carbide precipitation. It's when the heat causes too much chromium to evaporate from the heat effected zone. It destroys the anti-corrosion characteristics. Chromium makes steel anti-corrosion because the box centered crystal structure is filled with Chromium atoms, which severs the shared electron field of the centered atom, making oxidization less likely to propagate.
I have been tig welding over 30 years and glad to see you explaining and showing the techniques. I just wanted to add that the angle of the touch cup also has an effect to color. I consistently correct new welder who angle the torch to get better view will draw in air as a scavenging effect.

The most common issue I see in facebookposts, are people using too thick of a fillerrod paired with a way too "blunt" tungstengrind, causing them to overheat the piece because of the width of the arc, and the ammount of amperage they need to properly melt the fillerrod

I just recently had this problem and first thing I did was like you said to crank up the gas-flow only to continue to be disappointed and stop working :) It feels like such a no-brainer, but is so easy to forget.
Tight arc gets you a long way…. Hasn’t mentioned that directly

one thing to remember for someone just learning and welding on a coupon thats say 6 inches long x 2 or 3 inches wide .. stainless has low thermal conductivity meaning it will dissipate heat much slower than aluminum.....so that small practice coupon will will get hot very quick
A lot of good tips,thanks for your awesome vids🤗😎🤗😎
Well I've seen enough. Had to subscribe. It's the no nonsense, here's what I do style of videos that I like the most. No hype, no "I'm a better welder than you so you should do what I tell you" attitude. The double tap method seems foreign to me, but I can see it being really handy. Next time I have an aluminum job with outside welds I'm definitely trying it.
When I have that problem it's almost always a arc length problem
the content of your videos are packed with important info that my instructor didn't teach me. I just started Tig welding, I have a natural talent for It so I can't wait to learn more from your channel!!
If I could just keep from dipping the tungsten. My hand eye coordination is long gone, I learned to oxy/acet weld back in the 1970's then because of my trade taught myself to mig, now retired and trying to tig.Keep going back to spool gun . Great channel.

Are you indexing your torch hand, resting it on something as you move it along? Or trying to hold it up in the air? Think of a dentist grinding on your teeth. He's going to rest his hand on your chin... if he doesn't he's going to grind your teeth down to little nubs, because he won't have a steady enough hand to avoid it. Nobody does. You must index the hand that is holding the torch or the tool. Then, put in some practice time, and study time. Study. Practice. Study. Practice. Study. Practice. Little changes over time lead to perfection.
Whoa I needed this, thanks for putting stuff like this out there. You're so fkn cool Dusty, keep up the great work
There are two guys on KZread who explain basic to intermediate welding better than anyone else. That’s both you and Tim from TimWelds. Other excellent channels are much more aimed to the experience welder, where they assume you already know the basics. Some are in between, like Jody from Welding Tips and Tricks. Unfortunately once you get away from the pro channels, it’s difficult to find a good channel. Most are guys whose welding isn’t, well, the best. They need to learn rather than teach.
Just as well you're already north of the border. The merest suggestion that a problem will not be solved by ordering fancier stuff is downright UN-American, and if you were south of the line, they'd hogtie you and send you north! ;-) Nice presentation, as always. Clear, informative, and thought provoking.
Amazing information! I do have a question I am terrible with using the peddle I am guessing you can get the same affect with lift arc or scratch arc
Great info
Awesome video mate! Really helpful! Do you have any tips to make welding Stainless with scratch start easier?? Thanks!!
I'm in school right now. I'm running too hot. This will help significantly.
At last I know! Thank you!
After proper technique, a true color lens is what has made the most difference in my welds. The ability to see air penitrating the shield gas before it reaches the puddle, gives me the chance to adjust the torch to compensate or stop before the coverage is lost.

Best money I ever spent for welding wasn't a machine, it was going for a Lincoln 4C lens equipped hood. I can see everything so clearly now, and it's made a massive difference on my welds, and even arc starts. It's definite bang for the buck, with a decent enough hood and a top of the line lens. These newer lenses are miles ahead of the stuff from 10 years ago, and light years ahead of what we had in the 1990s. I liked it so much I bought 2 more- one for me, one for my assistants. The newer headgear is much better than the original, so I upgraded my older 3350 with it too. If anyone is on the fence- just do it.
Just watched a 7 minute commercial.. and no answer to the question posed.. one of those endless promise and wait for the answer, and... no answer. I was somewhat excited earlier today when found this channel, thought it would be another gem like the weldmonger, but naah..

Huh? The question is "What causes it" and the answer was very obviously TOO MUCH HEAT INPUT. It causes carbide precipitation, or a leaching of chromium. It's actually a pretty basic part of stainless welding- you have to move fast and use correct settings and can't dwell too long, or it'll put too much heat into your weld. Using low amps actually is just as bad if not worse than too high amperage, due to the dwell time.
Thank you sir
Good stuff brother.
Great video Dusty. 🪙🪙
Thanks
Great video dude. Question? Are you double tapping to mimic a larger diameter filler rod?
Hey could you please make a video of how to setup your machine and what amperage you recommend for stainless and aluminum please it would help me a lot
This is awesome.
I think I need you to look at my welds. I weld very thin tubes and either I struggle with too little heat (not getting a propper puddle) or the heat affected zone is huge.
Excellent!
Thanks, I like this, and I know too much heat is my problem. But I am confused too. I'm welding stainless about the same size as you in this video, and my amps are low, but my travel is faster than you show, and if I travel any slower I'm worsening the excess heat input. So, do I need more amps and faster travel? IF so, how do you travel so slowly and not overheat? In this video specifically, I think it would help a lot to talk about the material thickness and machine settings.
Well said.
awesomeness Dusty.....
GREAT INFORMATION DUSTY, I AM OFF TO DO A RANDOM ACT OF KINDNESS,,,,CHEERS, PAUL
When i see you setting your machine to 40 amps that would be your max but you can make it lower with your pedal? Im just using a very basic lift tig welder atm and i havent done much practice yet but this video helps alot i thought i needed more gas but i now know my welds are wayyy to hot
Dusty, I have also the gray problem, it to mutch heat input you say. So I get turn down the amps or go faster. Even how low I turn the amps down they stay gray. My tungston als turns purple. My postflow is 5sec. 1,6mm tungston color purple. And 7 liter a minuut of 100% Argon flow
Hey bro do you have a video on your welding table set up?
I have not seen this in your videos, but would love to see one on thin sheet metal. Like 18 gauge. I have been tig welding for a year and still struggling thin sheet metal. I find it reacts totally different to the thicker stuff. Most of the time I do very short passes to not put too much heat into the panel. But I find it either is not penetrating so weld is sitting on top, or penetration with an inch wide heat effected zone, or worst cases blow through. Thank you for your videos!

Back gassing really thin sheet is super helpful. It's not just for stainless and exotics but sometimes necessary for steel to avoid pulling oxygen from behind the weld and bubbling up.

1/16" tungsten and pulse should help
Your beast bro❤
the start of a weld is very important, the width of the weld, then follow the width of the weld, drop in filler wire at a steady pace, using pulse welding is good if welding in stainless steel.
Heat control is so important but I'm finding it difficult to master. I'll try the double tap!

I weld a lot 1/16"th thick 304 stainless tubing (car headers), I cap the ends a purge it (with a vent hole) it typically takes 30-35 amps (sometimes I will have my wife watch the amp gauge while I weld) to end up with a pretty, shiny looking weld but I do not get a decent weld on the inside unless I use more amps, to the point it starts turning grey on the outside. What am I doing wrong or is that just the way it is??
Limping in too cold is a big problem self-taught welders struggle to overcome. They limp in with nowhere near enough heat and by the time the piece is hot enough to fuse together, the entire area is glowing red hot and as soon as the shield gas disappears the heat comes rushing back to the weld area and discolors EVERYTHING. The key is to go in hot and get out of there as quickly as you can so you don't overheat the entire piece. That way, the surrounding area around the weld is still relatively cold and able to suck away the heat from the welding. It's all rainbows 🌈 and butterflies 🦋 from then on!
how far from the basemetal do you have your tungsten
hows it going, im an apprentice and i was wondering your thoughts of pulse welding on ss as it was a game changer for me and lets me lay out consistent dimes
I just started trying tig welding, actual weld looks good but looks like charcoal lol. I have the basic set up also, does tungsten diameter matter? Im using the one that came in the tig torch which is the larges of the 3 that came with it
I see kids in my welding class have their machines set to low thinking it's going to help the oxide problem when in reality their having to sit and heat longer making their welds gray so I recommend weld as hot and fast as possible
Hey brother, do you wish you just got the 255ext first rather then the 210ext? I’m stuck on what to get. I’m using it for automotive/ motorcycle fab. Turbo systems etc. does the 255 do that much more? Obviously amps is more but features? Thank you
Can you do a video of 4g stainless plate? Having trouble with it right now
Dusty, I'm having issues now and again when welding SS and steel with a super bright arc forming in the middle of my pass. I usually need to back off on the pedal to get it to go away. I am positive my work piece, filler, and tungsten are clean. At first, I assumed it was because I dipped or somehow contaminated my tungsten, but it has happened when I know for sure that's not the case. My set is .093 blue tipped tungsten with 2% lanthanated. I'm using a stubby gas lens kit with about 20-25 cfm of argon. My welder is a Lincoln 200 amp inverter type. Any help would be appreciated.
Looks like 3/32 tungsten and 1/16 filler rod on 3mm(1/8) material? I think where I go wrong is the filler wire. I’m using 3/32 filler rod. It’s too big for what I’m trying to do. Find myself melting the rod with the torch instead of the puddle. No bueno.
Does that oxide affect the strength of the material? Does the metal getting too hot cause it to be brittle?
Canaweld machine VS your Everlast what do you like better and why? how are the different and why?
🪙 loving your content Dusty
You rock dusty
hardest thing for me with tig and the reason i get this is i just get sick of waiting for metal to cool i just want to run joints lol i get this alot with mild steel.
Also, double check your filler rods grade numbers and SIZE !! Make sure use the right filler rod size to the working piece
Nice one 👌🏻👌🏻
Edge cups vs Furick cups, which are better?
Sometimes it seems like I need so much amperage to get a puddle established that I make a huge heat affected zone , what am I doing wrong ?
Hey! New Sub. Looking forward to the Vids.
I’ve always used a size 12 cup sometimes used a 9 in tight spaces just technique tbh if not just get a wire brush out haha
I am a pipe welder and I see this when you weld the following passes too close together. A temp stick is a good idea to prevent this. You can see that it is cooler but not so cold as to cause brittle welds. Usually the employer wants you working quickly to knock out the welds but taking a little time between passes makes for better welding
Yeet! Love this channel
Thanks Dusty , but one Question.Is there a special Fillerrod that could handle higher Temperature and is less corrosive? I just got some Chinese Rods here and i guess they are bad for shiny welds. I´m a Noob in Tig Welding and your Videos are so helpfull. So it will a be 100% techniqe problem but maybe the Rods du their Piece to my dark welds. For me it is really diffecult to get the small heatzone around the Weld.Too less Power and to slow is also to hot , what do you think about it?

If your welding mild steel the welds can be I little gray. Especially if you don't clean material well. Also clean your fill rod. For Stainless steel. Start arc and get puddle formed as fast as possible. Also move as fast as you can when welding.
I see you mention controlling the heat effected zone but i dont see you mentioning how to control it. Reduce amps, move faster, etc or did i miss it.

I feed the rod with every dab. It's easy for me as I've been doing it for years. It came from tig welding super thick aluminum, Preheat thick, multiple pass aluminum even. You have to feed the rod every dab.
i am just making long tube headers, all my welds are grey, i tried everything, tube is AISI316 , diametre 42.6mm, 1.6 mm tick, and used current from 40-60A and welding wire from 1, 1.6, 2mm and best is 1mm wire, and 45A to prevent melted metal to pass through tube and hang inside of tube, so, my travel is very fast almost too fast so it can not be to much heat input, argon is 4.8, 13 liters per minute, cup is 10
For those who are absolute noobs like myself: my welds were gray, I tried changing the amperage, the travel speed, the amount of filler rod, I tried cleaning it better and nothing worked. Turns out I was using a #5 cup with a diffuser on like 7 cfh. Switch to a #7 cup with a gas lens, turned the cfh up to 15 and now my welds are golden. It felt so satisfying.
any tips for welding thin stuff like 20ga without it going grey? especially when welding a shape where you cant get a copper backing plate on it?
