Spatter on stainless

[chunkolini]

Tig welding?
I did have a Tig welder and flogged it as I never used it.
the problem is I am after flowing the joints into each other, see immage below, a bit pixilated but basically I butt weld the bars (8mm) then weld over and between them to get smooth seamless joint between the components, easy in mild steel.


Tig welding this would take for ever.
With the new gas mix I can get the effect but it is much less controllable, I will have a play with anti spatter tomorrow and see where that gets me. I wonder if the usual argon/co2/O2 mix and anti spatter might be ebst in the long run?

Interesting stuff.

I see what you mean. Originally I was only thinking of spatter but really this bead shape is more important. You might be right with the anti spatter (or a chisel).
It might also be worth masking off around where you weld. Ive seen it done with Ally foil folded a few times and wrapped around. There might be something more "professional" on the market these days.

Hi Al
That is exactly what I was doing today, I have a roll of thick aluminium foil stuff, been sitting round for 10 years or so, almost chucked it a few weeks back, ideal for folding around the areas that have been worked on. A combination of that and anti spatter does the job.
Cut up beer cans might be a bit more professional looking.
A result!, a few specs of spatter but enough that popping it off with a chisel is an option.

I has been intersting researching gas mixes etc, so I have learned something, and so has my gas supplier.

I also spotted that a lt of the spatter on the test pieces was bouncing up off the bench, so I am going to weld on my plasma cutting box, it has bars to allow the debris to blow through.
