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 RU-vid, 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?

@fearkiller6393 2 года назад

When you weld do you control your heat or do you lift arc it?

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.

@hxhdfjifzirstc894 2 года назад

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.

@Tagawichin 2 года назад

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.

@ChevyConQueso 7 месяцев назад

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.

@Kneedeepingore 2 года назад

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

@jrcll7856 2 года назад

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

@thzzzt 2 года назад

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 2 года назад

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.

@ChevyConQueso 7 месяцев назад

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.

@pamike4873 2 года назад

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.

@seanprice6345 Год назад

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

@joshhooker7390 Год назад

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!

@JRP026 2 года назад

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.

@maxgrass8134 2 года назад

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.

@makantahi3731 2 года назад

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

@zanebritton7823 2 года назад

Goes to show it's not the equipment but the worker. I rock a fixed Jackson hood and have no problems. Imo I prefer how much definition they have compared to some autoshades.

@zanebritton7823 2 года назад

One other thing what are your thoughts on slapping aluminum plate on the backside of what you're welding? It draws the heat out but at what cost?

@noimagination99 10 месяцев назад

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.

@hxhdfjifzirstc894 2 года назад

That might be counterintuitive, but it makes sense, because it's like the difference between searing the outside of a steak, and putting it in the oven at a lower temperature for a longer amount of time. If you just sear the outside, the inside will still be rare. If you put it in the oven, the inside will be overcooked, by the time the outside is browned.

How do you know how to use the correct size diameter filler rods when welding? I weld stainless rails and I want to keep that nice profile weld but I don't want to lose penetration so I feel like I over fill the welds and lose that nice silver to gold look of the weld and end up with blueish to gold welds.

@carpediemarts705 2 года назад

Blue is hotter than gold. Find a chart listing temperatures of stainless colors. Rod thickness is related to your work piece thickness. Thin metal, thin rod. If all you have is rod that is too thin, it will require more rod per dip.

@lyster1ne681 2 года назад

Filler rod selection is entirely personal preference, it’s just a matter of how much you add. Generally speaking you want the rod diameter to be equal to or one size smaller than your material thickness. (1/8 inch plate, use an 1/8 inch or 3/32 rod). Just focus on your feeding and the width of the puddle and you can get the same results with either rod

I do custom welding and lots of aluminum with tig , with aluminum as I'm sure you know the biggest thing is prep work have a dedicated stainless brush to clean the area you're going to weld , then wipe with acetone also let your cleaning action work abit before you start dabbing your filler.. that is the biggest thing.

Not gonna lie, you say it's technique and then use a basic setup that looks bad. It's a combination of both. For most it's technique until you learn how to control the pedal. But once you've learned how to weld the equipment makes a huge difference. If I have to use a generic setup my welds don't look all that good. I'd honestly rather mig it if I can't use my setup. If I don't have my specific cup/lense setup I will always get worse results than I'd get with a standard cup. I've heard a lot of old timers say "you don't need lenses for anything". And for them it may be true. It just depends on what you are used to using. My standard torch welds look like ass. My lense welds are pinterest worthy.
