Why bother?
The main benefit of extra receiver lugs is about increasing bedding life, not about improving accuracy.
Welding to a firearms receiver would involve you in follow up stress relieving and re-heat treating, otherwise receiver warpage and loss of hardness, or too much hardness [ dangerous brittleness ] could be a very real possibility.
The regular M14 receivers, glass bedded, or bolted, or whatever method of attachment you choose, shoot pretty good already, as long as they are attached to the stock TIGHT!!
I am involved in a couple of projects involving aluminum and the M14. One project is about creating a NEW Canadian made munimula M14 complete stock ...
basically a blend of the AKM/TROY/ etc., but better AND cheaper.
AND,
I am also working on a long, munimula channel bedding block for the M14 action, similar to the Savage alloy bedding blocks, which could be attached [ glassed/bolted/welded ] to almost any type of stock, and shoot well. My design is more about attaching the op rod guide to the bedding block, and free floating the barrel. I am interested in reducing barrel whip, and achieving more consistent barrel tension at the front, rather than tightening the receiver-to-stock fit at the back.
While both ends are important, we already pretty well have the back end covered nicely without any extra welding.

Stay tuned ....
and if you really want it SOONER, you could send $ 100 bills, stuffed into a plain envelope, to encourage me to work faster.
