Ceriated tungsten does'nt work very well using AC and a sycrowave machine. But does work fine with a inverter machine like a Dyanasty, but not recommended.
Hey Lawrence,
We had three new guys that were consistently running aluminum beads that would fail an x-ray NDT. It was always 1/16th aluminum every other thickness they would do just fine. We are talking about very, very small crescent blip on the x-ray so much so its hard for me even to see it( I'm still not sure I even see it at all) but the x-ray tec says it's there.
So told him run me some beads and let me see what your doing.
He set it all up and everything looking great and then he reached and grabbed a 3/32 filler rod I didn’t think much of it, wouldn’t be my choice but you know so what…until the lab results came back and I quote “hydrogen porosities due to sudden chill of weld pool” I thought 3/32 filler rod. The guy swapped to 1/16th problem was gone.
Have you ever seen or heard of this?
