Metal Fabrication: How to TIG Weld (Series Teaser)
Sep 27, 2022
www.proshaper.com Wray has decided to do an all inclusive TIG Welding series! We get a few questions regarding what we use and what the best method is. In this series we hope to showcase all TIG Welding methods. Explaining what types of tungsten and gas is used, using pulse vs not and then we get to stress test our welding by beating the panel with a ball peen hammer to see if the welds hold. We are getting a nice little shop on Amazon where we are putting up any tools or books Wray uses and recommends! We just created it today so there is still more to come! https://www.amazon.com/shop/proshaper Email: [email protected] Website: https://www.proshaper.com Facebook: https://www.facebook.com/ProShaper/ Instagram: https://www.instagram.com/proshaper/ Twitter: https://twitter.com/ProshaperM Linkedin: https://www.linkedin.com/company/proshaper/

Hi, it's Ray from Pro Shaper in Charlton and I'm not dead yet
0:12
Tonight we're gonna do The start of I was gonna do this all-inclusive one-shot TIG welding deal on aluminum
0:21
But it's such an enormous subject. I just thought about it There's no way I'm gonna have to make it into a multi-parter. So I'm just gonna do one sample tonight again
0:32
We're limited in time. Mark always has to seem to leave. I work 80 hours a week
0:37
He doesn't want to eat work 80 hours a week. I don't know what's wrong with him
0:42
What's wrong with you? So we got a sample that one of the students wheeled up and it was just a piece of scrap hanging around and
0:56
I Cut it in half with a band saw It wasn't sheared so the joint is pretty decent. It's not a perfect joint, but it fits pretty nicely
1:06
so my intent on this is After I band sawed it I took some 80 sandpaper and sanded the edge of the fuzz off from the bit from the bandsaw and
1:17
Then I've given it a little cleaning with the stainless steel brush. So now I'm going to to
1:25
Clamp this up the way I usually do I usually start in the middle of the panel and
1:31
I'm going to tack it up this one. I'm going to tack without the pulse. I've been tacking
1:38
but I'm going to do this a method that One of my students from the Netherlands came over Martin and
1:48
And he showed me this technique. I'm gonna redo that technique now the difference is we were using
1:57
Just straight argon, but now I use argon helium Exclusively, so I don't know what the results will be so we'll give it a shot
2:06
And see what it looks like and then we're gonna torture test it will clean it up and torture test it
2:11
I probably won't weld the whole thing maybe just portion of it
2:16
but the torture test will be Taking it over to the beater bag and hitting it with a ball peen hammer as hot as I can swing the hammer
2:25
Right on the well to see how that weld holds up If everything went well, the weld will be as strong as the parent metal
2:36
Need one more clamp there we go Let me just get a hammer I can pump that together one second
2:46
So I'll even tack
2:55
I'll try to pack without using a rod. I'll have a rod and reserve in the case that a hole opens up or something
3:02
but If I can tack without Raw that's what I'll do So
3:15
I'm using 1100 rod. This is the Chinese super stiff 3003 allegedly
3:26
H14 allegedly 63,000 stick Aluminum I've come to like it, but it is tough
3:37
It wells nice I've got a 2% Lanthin aided rod. I grind it about a quarter of an inch back
3:45
after you grind it you should burn it in and It a little micro ball will form on the end and it's pretty stable when you use thorated
3:54
The ball will get larger. It'll get wonky on you have to clean it up
3:59
This will get a little larger after you use it for a while but it hold pretty good too So that I really switched that a lanthanated both steel and aluminum and I use this IV
4:11
Hanger here to hold the weight of the cord So I'm gonna try to do some tic tacs here with no pulse
4:18
I'm attack this up and then we'll weld it up You
4:35
See that's hop skipping and jumping along really nicely My heat is at 76 amps it might be a little strong I
4:46
Could back it up, but I'm just cracking the pedal too. You want to make sure the metal is flush. That's super important
4:54
On aluminum, it's a little forgiving on steel. It's not if it goes off on the steel. It's a pain
5:12
The vice grips give me a nice rest for my arm so I can control
5:19
Better I Tonight I don't have time but in the second and maybe the third video on the TIG welding of the aluminum
5:39
I'll call out all the settings I do and You maybe try that there's so many variables on today's inverted welders with settings
5:50
There's a at least a half a dozen or more settings so it can get super confusing
5:56
Not only do you have to have the eyesight and the hand coordination, but all the settings
6:01
the foot pedal control And
6:26
And after I get the aluminum TIG welding on the agenda will be we'll do some steel TIG welding eventually and
6:37
This is all sheet aluminum sheet steel sheet and and A lot of my students before they come to my class will take a welding class at a community college or something like that
6:51
That's all well and good for welding structural stuff, but generally they will not weld
6:56
thin sheet metals because a lot of those welders the instructors do not know how to properly weld
7:04
thin sheet metal I
7:34
All right a little bit of gap was forming over there and it opened up I had a little rod right there
7:41
So now I got this side all tacked up The tax came through but they're not really well that you could break this off very easily. There's no strength in those
7:55
So what we're gonna do now is just give it a quick little Why a brush treatment
8:13
Now I wanted to do a shape part because generally if you do just sheared coupons
8:19
What happens is they'll lift up like this now just didn't lift up
8:24
So that that'll Stay pretty stable now what I'm gonna do is I'm gonna follow Martin's technique of welding the backside
8:33
first Which as he explained? It doesn't have any strength component to the weld all it's doing is closing the back door to keep your oxygen
8:44
Oxygen is the enemy keep the oxygen off of the weld zone. So here we go. I'm going to just run that
8:53
And we'll see how good I've got it set at 76 amps It might be a little too high so I might have to stop and lower it. We'll see but if your amps are high
9:02
You can use that higher amperage, but your your dwell time is faster. You've got to move faster
9:09
the object is to Get a lot of heat into the panel without blowing a hole into it and without slumping the metal too much on the other side
9:18
So we'll see what I'll do a little bit and see what happens here you
9:37
It's going pretty sweet You
10:09
So you mark and get a close-up of that you can see
10:13
We got a little bit of drop through on the other side but that's a super clean well and
10:21
Very hot with that helium the helium makes it a little harder
10:25
We'll do the same thing with just the argon and we'll compare the results
10:30
So there you go That backside you saw that that was pretty quick when you're doing it that
10:39
Fusion method it's fast So I got the backside done now I'm gonna do the front side the front side of probably as fast
10:47
The question is after we planish it out will there be undercuts most likely there probably will be which you can go in and
10:55
And fill with a little rod here and there. We're not going to do that
10:59
We don't care about the aesthetic so much on this example. We want to see the strength element and
11:05
What kind of results we're getting just for doing it this quick with this type of method
11:09
And this is just one of many many different types of methods that you can use
11:14
And it literally can spend weeks Experimenting to find what works best for you both in your welder your settings
11:23
Your conditions of your eyesight and your hand-eye coordination All that comes into play. It's actually you know, there's so many variables. It's an incredibly complicated problem
11:34
But you can't get scared by it. It's just a piece of of Tungsten throwing off electron stream, which is just nothing more than electric flame
11:43
It's exactly the same as a gas torch, but it's electric flame and you're controlling that electric flame
11:50
But you don't have to have any flux so here we're going to run this one
12:36
All right, so there's the top side and no rod was added
12:44
And we got a lot of drop through here now on the backside if you look at this weld on the backside
12:49
It is the metal is shiny clean. It is beautiful Now I suspect what's going to happen here. I had probably a little bit too much amperage. I was a really hot well
13:00
Hopefully we can put this in the planishing hammer and cold forge that extra drop through material
13:07
Up to the top and then we won't have as many Divots or any problems on the top
13:13
But then we'll do the torture test. So I want to let that cool down for a few minutes
13:18
So we'll come back in a few minutes. I don't want a water blast. I'm gonna let it just air cool and
13:24
And then we'll come back. All right, Mark is severely pressed for time
13:29
So I decided to use the power hammer instead of the planishing hammer I'm going to crush this all in and then we're going to do the torture test on it. So here we go
13:48
It actually looks pretty good it crushed in nice backside It's got a little bit of edge on it, but the topside
13:56
It looks pretty decent now we'll run it in the wheel just for a minute and we'll torture test it
14:06
Give it some heavy pressure Alright and there's the
14:24
The surface is a little bit of undercut over here. Not bad altogether pretty nice
14:30
So now we'll do it the torture tests with the ball peen hammer. All right now
14:34
Let's see what we got. We have a ball peen hammer an old beat-up ball peen hammer. We've got a beat a bag
14:39
And we'll start hitting right on the well It
14:56
Fatigue cracked on the side of the weld on this one right here not on the weld on the side of the weld
15:04
Let's try it some more here Same thing started the fatigue crack right there. So effectively what you have here is
15:31
The weld zone is as strong as the parent metal. So that's one way of welding
15:40
Aluminum with a TIG welder. We're going to explore as many ways as possible in the next coming weeks
15:47
Tomorrow maybe we'll do another one. Thanks for watching. It's ray from pro shaper
