Great cleaning before you weld to improve penetration and fusion. Thanks for an "Excellent" learning experience. T J (Tom) Vanderloop, Author, Instructor & Manufacturing Consultant (AWS & SME Industry Leadership)
New question. While practicing TIG welding a T-Joint weld on 1/8” plate which has been cleaned (including the bottom edge of the vertical T) and acetone wiped, I experience the following problem. I tack both sides to keep the vertical piece straight up. Then weld one side and it comes out fairly good. For safety I reclean the unwelded side. When welding this side of the T-Joint I get a lot of porosity and a horrible weld. Contamination! I did have it down to clean bare metal, so any suggestions would be greatly appreciated. Thanks for all your videos!!
+Tom Herd My first thought was you screwed yourself when you cleaned it again.. Or maybe you grabbed the wrong can when you cleaned it the second time.. That's all I got......
+Kevin Caron, Artist From more checking it seems I put too much heat into the first weld side causing joint oxidation leading to porosity, etc. Tighter arc, smaller weld for less heat, ….. however, T-Joints on thinner metal is typically problematic.
I'm currently watching a UA-cam channel "bad chad" who is building a car right now. He doesn't clean 95% of the metal, and actually covers up surface rust with new metal. It just blows me away...and this guy had a tv series for a couple years "bad chad customs " on discovery I think.
How do I make the rust not come back? Lol...getting a wheel well repaired with new metal and people keep saying the rust will come back. Esp at the weld spot in future because water will somehow get in...really bummed about this because I just got the car smh.. can I Plasti dip over the repair to ensure no water ever comes into contact with the weld repair again? Lol. Best options to make sure the wheel well doesn't rust again at the weld spot ? Thanks for any replies. Need some optimism lol. Going to be paying $800 for a wheel well repair ( cut out old metal and weld in new )
Well, you can paint both the inside and the outside to help stop the rust. You can have the repairs done with stainless steel to cut down on the rust. Or you can do the repairs with aluminum so nothing to rust. But if you just paint the metal on both sides you probably have 20 years or so before you have to worry about rust.
@@KevincaronSculpture thanks for the reply. Shop that is doing the repair say rust will come back within 1 year after welding new sheet metal. Hoping it doesn't come back at all. Can I spray it with rubber coating to protect the area. Still have 5 years of payments left.
OKaaaaaay, maybe I will try that fancy cleanin' idea. Even though I live a TIG free life, I suppose it won't hurt to clean 'em before I 6011 'em... Thanks guys!
Thanks , Kevin ! I was wondering why I got some 💩 shitty welds ! I welded some rusted truck frames and 6010 and 6011 electrodes would light up easy enough , but 7018 electrodes wouldn't even get a spark , once cleaned up the welds looked nice and normal again ! Since I started welding again , I got my beer belly back ! Comes with the territory I guess ! Thanks for the video ! Think I'll have another beer ! Cheers !🍺
I need to show this to the engineer working on houses nearby where they are just welding rusty connectors to heavy cement and steel wall panels for 2 floor houses.
Depends on what their using. Example....some stick electrodes have no problems burning through some light rust. Like 6010 type electrodes. That what makes them so great out in the field in less than ideal conditions. Depends also on what type of welds.
They have no choice, on a job like that you can't clean everything. They are also not using TIG. They're using a stick welder and with that you can weld almost anything. If you can clean your work of course you should, but if you're using a stick and there's a bit of rust it won't stop it. I spent my youth welding rusty, painted metal with my old Sear's Crafstman AC stick welder and never had a weld break. For MIG or TIG, those processes prefer nice clean work material.
Unless your planning on MELTING the netal, as then the rust and bad stuff will float to the top, and you can scoop it out! But IF you get ridd of the rust and stuff, BEFORE you melt ut, there will be LESS for you to scoop out!
Is this primarily an issue with TIG? What about MIG? I didn't know mill scale was an issue, I always grind off rust and paint but I usually don't bother with mill scale. Interesting.
Doesn't grinding the second one for better conduction make your experiment invalid? Because maybe the better weld is due to that and not the impurities???
+Kevin Caron, Artist LOL busted. Glad you made that video about that. I sweat my ass off welding in my garage this time of year and been attaching my ground to the work when possible.
i was doing some welding at my job once and the head boss came in and told me to stop wasting my time grinding down the metal because if i cant weld through a little paint than i aught not be a welder.
I love your channel, but I would much prefer to see you teach as you go along a build of yours instead of simply teaching the basics. Show us your projects from start to finish; I yearn for your builds in detail. Do with this what you will.
I study in 10 class and i am from india. I'm 15 years old . I want to build my own car. My design is ready.the design is like a muscle car.dual exhaust ,v8 engine, for barrel carb. So can i get a 1969 mustang body it doesn't matter crashed or old. I will pay you for this
@@KevincaronSculpture Sir i respect u but i don't have much money to buy a car frame. If i choose any car it will take a lot of time for me to change its shape . I will search it myself . Thank u so much
Well said, I've liked watching these videos by him for years. Are very good information.
Glad you like them!
Thank you Kevin for explaining and giving examples of the differences between clean and not cleaned welding. 👍
No problem 👍 Thanks for watching and posting. Have you been to my website yet? Lots to see over there as well.
I really appreciate all these videos Kevin. 🙂
Great to hear! Thank you for watching and posting.
Very well explained sir, respect from INDIA

I learned this lesson the hard way. Now I always clean my metal before using my everlast welder.
I hear ya!
The three Cs of welding - clean, clean and clean. I got that knocked in my head as soon as I started to learn how to use my powertig welder.
Amen !
Very-very helpfully
Thank you for watching and posting.

What about blue primer on mild steel?
If you are going to weld that spot you need to get EVERYTHING off the metal. Clean and shiny is the best way to get the great joint.

Are you tacking those first, to hold the position? I'm not sure otherwise how you'd keep them so close.
+mlindholm Nope, not tacked. Just sitting on the bench.
But I do miss the popcorn and fireworks. doing a good job.
Is acetone a safe cleaner? What is the best cleaner?
I use a surface prep disk or flap disk. Have never used acetone.
what is the welder brand and model. is it a tig mig combo ?
That is a Everlast ProMTS 251si. Mig, Tig and Stick machine. You can see it here.. www.everlastgenerators.com/product/mig/powermts-251si-tig-package
Not to mention all the shit you breathe when you don't clean it.. learned that the hard way lol
When you blow your nose and get black stuff in the Kleenex it is a bad sign!

+DopeItUp I have had issues with MIG as well.. Porosity being the biggest one..
Thanks Kevin. Keep up the great work, I'm no artist but your tips on various welding and tool usage is absolutely top-notch.
Typically I rarely see issues with mig and mill scale.
Some processes are more forgiving of dirty metal than others. TIG requires clean metals.
How about metal with oil?
Needs to be clean and dry. No oil!
Doesn't grinding the second one for better conduction make your experiment invalid? Because maybe the better weld is due to that and not the impurities???
Sorry , can't think of everything .
Why are you attaching your ground to the table? Didn't you get shocked last time?
+firearmsstudent Head hung in shame! You got me....
+Kevin Caron, Artist LOL busted. Glad you made that video about that. I sweat my ass off welding in my garage this time of year and been attaching my ground to the work when possible.
That AND metal oxides are crappy conductors.

Has no idea what he is talking about and will get someone hurt if he thinks that is good advice.

holy cow, its Terry Wogan.
Okay,,, that's a new one....
or dont use tig... use a stick with flux
