I'm a lazy stinking tigger!

I'd like to TIG weld some sheet metal on my Honda project. I was thinking of TIG welding the patch pieces in without using (little or any) filler rod. Is this an acceptable pratice? I want to minimize grinding.

I've got this monster Airco TIG welder that could weld shit to a rock. I just never use it.

You think it might put too much heat in the metal and warp things? I know MIG welding would be quick and dirty. I'm sorta a TIG tard.

Fock no.

TIG actually heats the surrounding metal less than MIG and you run less risk of warping body panels if you're impatient.

I think without filler you will have alot of holes, unless you are a tig god.

I have filler rod but I was looking to keep the bead as small as possible. Also, since the car is a 38 year old Honda, the original sheet metal is almost thin enough to see through it.

Only thing is that no filler welding is going to be undercut, even if it is just a teeny tiny weld or tack. Obviously it won't be terribly undercut doing small welds, BUT you might end up grinding more of the surrounding metal off than you'd want. Just use a thin rod to keep it flat.
