As suggested...better results with multiple passes...

What do you refer to as pass? A single sided fillet weld will almost certainly break if hammered so the weld opens. Its just joint physics. You just need to observe what happens in the weld zone when it breaks. Yours looks fine for a beginner, as tig is very easy to get lack of fusion on. This is b...

I feel I've seen everything Jody has done. He's into measurable, or at least repeatable destructive tests. How big is the hammer? Who, or whom? swings the hammer? What your hammer test does show is that penetration is not what it could be. Single pass welds have attributes we desire. Less distortio...

The direction you apply the bending force can also make a good weld fail sooner than it normally would. I was hamm...

I love it so far. Thanks

I will run another bead and post before and after pics in next couple of days. Does anyone know why the amps listed on the MIG machine suggest so many more amps required to weld same metal thickness?

Got my first TIG welder about 3 weeks ago. Have been MIG welding on and off for several years...shadetree mechanic. Anyway I am struggling with the concept that I had seemingly conquered in MIG welding, i.e. creating a single pass fillet weld using, standard parameters, that will pass the hammer tes...

New to forum. I am hobbyist with Miller MM252 which I have had for 4 years or so, and new to TIG. Recently purchased a Lincoln Square Wave 200. Thanks.
