Mauser 98 bolt welding

Oldtimers didnt have TIG

They didn't have a TIG but brazing and or welding with a oxy/acetylene torch and a rod would work quite well.

I had a friend with the tig setup that utilizes a foot controller. He said that once the puddle is made, he was able to lower the temperature. That combined with the steel heatsink from Brownells, he didn’t even need any heat paste. It made a very nice bead that I was able to clean up with jewelers files and a bit of sandpaper. That cam near the bolt root is still as hard as it was before. PM me if you’d like to borrow the heat sink. It’s for a large ring 98.

No the old timers did not have Tig but it's no reason not to use it where is available to you. It does focus the heat a little better.

Absolutely correct the cocking cam is the area to be concerned about, the fit of the parts is vital the handle & stub of the bolt body needs a "weld prep" ground in to it, set it up in a jig use a heat sink in the rear of the bolt & heat resistant paste , tack weld it top & bottom check it for fit & alignment then complete the welding, a MIG works well with .8 wire practice on a 1/2 inch bolt or steel rod first you can not afford to screw this up. the other thing is to cover the entire bolt body
with wet cloth or anti splater grease to stop weld splatter if using a MIG.

Please do not attempt to weld with a Gasless mig, flux core wire it will turn to shit!
