In this video, I want to explain a problematic weld that I call the inconsistent weld
0:06
That's not a product of a poorly adjusted welder. Not usually. It's more an issue of hand-eye coordination and not getting things right
0:16
So there are a few parameters you need to keep in mind. One is gun angle. I like to go at about a 45 degree angle like this
0:25
Now there are also two ways you can move the welding gun. You can kind of drag it along like this or you can push it along
0:34
I prefer the dragging along method and it's probably easiest for you as a beginner to
0:40
go with that route too because the visibility is a little bit better
0:44
You can see the puddle better. You can see where you've been better
0:49
I find it just works a little easier. Now 45 degree angle, that's one parameter
0:54
The other parameter is the distance. You don't want to get too close
0:59
You'll see you don't want to get too far away. You also need to move the gun in a consistent and straight line
1:07
So when I say straight line, that doesn't preclude the fact that I'm moving the gun
1:13
back and forth to make a wider bead. But the overall pattern is a straight line
1:20
You know if you're all over the place, well your weld bead's going to be all over the place too. Really it's a function of learning to be a consistent welder as a function of
1:31
practice and the right kind of practice. To help you practice correctly though, let's go and take
1:37
a look. I'm going to fire things up and I'm going to make some mistakes on purpose so you can see
1:41
what I'm talking about. So here I am striking the arc and I'm doing a kind of normal weld for the
1:47
first little while. But now I'm pulling back and you can see the problem setting in. We don't really
1:54
have any penetration to speak of. Now I'm going closer, closer, closer and whoops, we got a problem here
2:02
So that mistake there, getting too close, not only made for a bad weld but it actually caused a
2:08
problem that I'm kind of glad it happened so I can show it to you. The wire got fused to the tip
2:14
So that basically shut us down. It's not as bad as it looks or I hope it's not as
2:19
bad as it looks because usually you can kind of break that off
2:34
There we go, we should be fine now. That tip's still in reasonable condition
2:44
So I'm going to continue with the bad welding demonstration. I'm just going to show you
2:50
I didn't quite get to showing you an incorrect angle and what that looks like so
2:57
we'll do that now. So I've struck the arc and now I'm going to draw back the angle, shallow angle
3:06
and you can see that this is, you know, affecting penetration. I'm going straight up and down here
3:11
I'm getting better penetration but now the weld bead is narrow and just overall quite inconsistent
3:19
as you can see. Come and take a look here at the inconsistent weld. This is the one you just saw
3:26
being laid down and you can see where the angle changed, the distance changed and it's just a kind
3:34
of an ugly looking weld. Penetration is not bad actually. I mean you'd want it better for a weld
3:40
that counts but really this is the problem of not being good enough yet with hand-eye coordination
3:49
and the solution is just practice of the right kind
