I need to join the ends of a 1/8 SS ring made from 1/8 308 TIG rod for tuna fishing. Can they just be fused with a sharp tungsten , or is filler needed?
 
Can’t imagine you would need filler. That said if someone with actual experience I’d tend to go with it.
Filler would be the same material, right?

I’ve done gas welds without filler, TIG should be the same.
 
Same 308 I have 1/16 TIG, and .025, .030 MIG wire.
 
I wouldn't think that filler would be needed. Needle sharp 1/16" electrode.
 
What type of amperage?
 
That'll take some experimentation!:) I'd start down low at 30-40A or so and work up until it puddles/fuses quickly. If you have a piece of copper to put behind it that would help. That thing will get hot really fast, and it will be easy to blow it apart. Pulsed may be worth a try if your welder has that option. Going to be a fine line between not enough, and too much.
 
:)non pulsed Miller Syncrowave 250.......
 
I'm only looking for strength., I'll see how the under cut looks..
