Tig break test.

[Mark @ Everlast]

I THINK, you may have gotten different results with 70S-6 filler.

Why is that Mark, is the ER70S-6 stronger? Seems like I was looking for -6 but had to settle for -2.

 

[Mark @ Everlast]

70 S-6 seems to wet in better, and has a high level of deoxidizers. And in my experience is fairly ductile.

That's because you're better than me! :thumbsup:

I doubt that. If I came off sounding arrogant I apologize.:ashamed:
I don't even have any formal training. I pretty much taught myself what I know and that isn't saying much.
What you're saying is a 1/4" weld is probably a correct weld,compared to what I would think it is.

what amperage are you using, what kind of tungsten, and what gas. (argon or helium)

I use a Lincoln Idealarc 300 AC/DC,not sure of the year,but I think it's from the late 80's early 90's.
When I weld 1/4 inch plate,I have it set on high,36/215,but I have the fine control on about 7.5,so I'm not using the full amps. I use 3/32" 2% Thoriated, "red" and 1/16" ER70S-2 rod (in fact the 70S is all we've ever bought).Gas is 100% Argon.

Ahh the classic lincoln idealarc, oh how I wish I had one of those.

 

[deereman75]

I saw you can buy tungsten in 7 inch lengths, I am wondering how you cut them, isnt tungsten incredibly hard?

score it with a grinder and it will snap with minimum pressure.

 

[Shield Arc]

What I do is put them 45 degrees to the outside edge of my bench grinder wheel, grind a groove in the tungsten, then break it over the edge of the table. Then grind the desired point on each end.

 

[deereman75]

Ahh ok that makes sence. Also how much differnt is tig welding from gas welding, like if I am good at gas welding, how hard would it be to get good at tig welding.

They say the fastest way to learn Tig is to start with O/A. I haven't done any O/A welding in just under 100-years:laughing:, so I can't hardly remember what it's all about. I do remember it being very hot.
The similarities of the two processes are, forming the puddle, then dipping the filler. Personally I think Tig welding is easier to make a nice looking bead.
