OK, so you may already be painfully aware that I've taken up (slowly) welding.
Spent a few hours already practicing. Mostly with TIG. If I may say so myself, my practice "welds" on flat plates are starting to look pretty nice. The butt welds are pretty good too, but the concave fillet (90o) welds are terrible. Booger welds are nicer than those....
I think I'm battling a couple of issues. For one thing it seems like the gas is blowing too hard, sprays molten stuff around, and maybe even the arc a bit. Likely because of the funnel effect due to the geometry of the plates and how I hold the gun? The flowmeter is set to specs per manual (20 I forgot what units). I could try to lower that.
Also, it seems like the arc is often attracted more to one piece than the other. (Electrical contact issues, or heat sink effect if one plate is on the table?). Seems like the pool is skittish, goes from one side to the other and the added metal stays there as ugly blobs.
So, any suggestions specific to fillet welds?
