Hi all,
I’m a complete beginner to tig welding but am having some trouble with some kind of porosity issue which I can’t get my head around. I’ll often get quite a lot of sparking and spatter no matter how well I clean everything. It also sparks if I weld without any filler rod.
Im using 100% argon. I grind down and acetone all my steel, as well as acetone my filler rods. Gas is at around 15cf, can’t find any leaks anywhere and can clearly hear it coming out. Tungsten is ground on its own separate disk to stop contamination, but because of all the spatter, seems to get contaminated pretty fast.
I read once that some mild steels can have zinc in them? Could this be the case?
The only other thing I can think of is where it’s been sparking so much, the end of the ceramic cup has burnt out. Could that be causing the issue?
here’s a photo of my first welds where sparks were flying! As well as the end of the gas cup. As you can see there’s a fair bit of spatter around the welds.
