Tig Weld

how do u tig weld a rifle barrel?

I have a winchester M70 tht i got from a friend and it had front and rear sight on it but thy are not on it and I wnt to tig weld the grooves tht are in the barrel whre the sight u-stow be and i need to know wht i need to do ths,thanks

1.) Don’t weld it up. Fill the empty slot with a dovetail blank and have it filed down to match the contour of the barrel and blued to match. That way the heat treatment of the barrel is not effected and the dovetail is still there if someone needs to mount a sight there at a later date.

2.) Have a gunsmith take care of it so it’s done right.
