I'm looking for someone with firearms knowledge to do some micro TIG welding. I can supply the pieces preshaped and ready to be welded.
Anyone have any leads or info?
Thanks! -Al
what is your definition of "MICRO" within the term TIG
micro by definition is millionth, and nothing gun related is done in the millionths scale.
I don't know of any TIG machines that can strike an arc to facilitate "MICRO" Tig welds
---
I have Tig welded razor blades together, and that still requires 6 Amps to even get the Arc established
Razors are not Micro
---
I can do some fairly small welds with my Miller
However for anything finer than this, a more specialized machine is needed
Like an Aerowave or a Dynasty, or something even of newer tech.

Keep in mind, depending on the parent metal, some are more difficult to establish an arc and sometimes fight keeping a nice smooth uniform puddle the more carbon the steel has in it.
(IE: some gun parts can be difficult to produce as nice of a weld as say Stainless)
Whatever project you are doing, the welder would need to know the composition of the parent metal to closely as possible match the composition with the filler metal
Otherwise your part may have to be simply open to experimentation.
For example I've welded some things that resisted welding, not being able to tell the parent metals composition, requiring a little trial and error, sometimes it ends up bubbling, which wreaks havoc
Something you think is steel may be cast iron or something having an unknown percentage of (Carbon)
And if experimented on, well, may not turn out pretty unless you know exactly what its composition is.

For instance, I may be able to TIG small, IF, I know what the metal is
without knowing, I have to try different filler metals such as Nickel, Silicon Bronze etc
This type of work may not be cheap

To get what you want, you must be very specific, because welders like myself, you have to treat more more like a metallurgical engineer, ....we don't like to have to -- guess.
Be very specific in what you are looking for with no vague descriptions, try not to generalize and expect the other guy to just "Know" what you are talking about, guys like me are very specific,
you get what you ask, if you don't ask and don't specify or call out tolerances etc, you then leave it up to the other guy to generalize or make it work and get what you get. Make sense?

If you need finer than what I am showing here, maybe look for F1 Chassis welders
---Pic 1 is .050" wall , 1/2" OD SS tubing
(when I say be specific, dont do things like call tubing, Pipe)
---Pics 2-5 are of a Rocker arm I had to repair for a Polaris engine, Filler rod used was .040" dia drill rod held with small Hemostats, drill rod which closely resembles the attributes of the hardness and toughness of the rocker face, then surfaced down to flush again after filling the gouge.
---
Regardless, if you don't require smaller than what I am showing here, I MAY be able to do what you need, but need more info
