Is this POS double a monoblocked barrel design. High heat input from TIG would most likely pull the barrel chamber at the rim "Out of Round" and as heat transfers through a pipe (gun barrel) you would have to use a copper plug to dam or localize the heat, which when input of same hits the rim, will move around the circle of the rim and chamber- odds are about 9 to 1 you will do far more harm than good. Agree with the "Bubba" analysis of the build-up weld as shown in the foto. RWTF
