You are overthinking every aspect of this project

With a Tig torch you can weld mild steel to tool steel. Just run the torch over the tool steel until it melts, and let the heat of the molten metal melt the mild steel.

But I would not try a weld like this as a first time welder on a $240 custom machined product. Find another solution

I already said please

I got a degree in welding and did a 3 years of training and I can't even get an entry level job, went into the military as a welder got out, still can't do it, so now I am going into Industrial automation, to get my vengeance against Joe Boomer, 20 years of 1 year experience in welding.
