how small can welds go?
I'm working on a design for a new product at work, and space is critical. I'm trying to get a mounting plate welded (.125" thick) to the back of a face plate(.109" thick stainless steel) I was going to use the weld to act as kind of a seal for the internal components. How small can a bead weld get with out getting to expensive?

Can you give an idea of the weld "joint" ? Is it a "T" or an "L" or a lap?

small welds
laser or electron beam can leave almost no bead at all. But they are expensive.
If you undercut the parts, a TIG weld can be made with little or no bead protruding. And still be strong. Micro-TIG can weld foils in the .001" range, but likely won't be strong enough. You will have to balance the small bead with necessary strength. Brazing may be an option. Braze can be flowed in with almost no fillet. (.015") Good luck.

How Small?
Like Bill says, a very small bead can be done with a TIG torch simply by fusing the two together, no filler needed. I have done this fusing technique on some very thin pieces as well as some quite thick pieces. I would consider the material you are talking about to be quite thick.

Laser Welding
Hi Kris, dug this up from a while back, it might be a bit too small, if you look at the bottom of the thread the photos tell it all, we used it for repairs on plastic mould tools.
