You can weld 4130 with stainless rod. 308 stainless alloy is used to weld dissimilar
metals together. Although I dont understand why you have to change the rod
because you hold the rod in your hand as you TIG weld. Unless it is a very
special welder that is using wire.

Subject: Pietenpol-List: TIG Welding question
Can you TIG weld 4130 steel using stainless steel rod? I use mild steel rods when
using OA to weld 4130 but don't know about TIG or using stainless steel rod
for 4130.
The reason I ask is my son has access to his company's TIG welder but for some
reason it is problematic to change the filler rod.
Thanks,

We use 308 LSI rods for stainless steel and mild steel (TIG). It should
also work for=8B 4230 since 308 rods also have Nickel and Chromium. 4
130
contains Chromium and Molybdenum so you lose alloy elements if you use mild
steel rods even in OA.
My 2 cents

Jerry,
My son works for a company that supplies and repairs transducers used in refineries,
so he and the TIG machine have to be "certified". Also he can't use the
welding machine by himself for safety reasons. I think it does have a wire feed
because most of their welding is done on very small, stainless transducers
and transmitters.
It's just awkward for him to weld home projects but he can do it.
This welding project for me is my landing gear as I am converting it from bungee
cords to the steel spring shown on WW's blog:
https://flycorvair.net/?s=spring+landing+gear
I could weld it with OA but it would look like crap! My son has welded small,
non-structural pieces for me on my Aircamper but was a bit worried about this
being the landing gear.
Thanks,
John F.
