JB Welding

[eric1911]

Which JB Welding could be used to do a cosmetic repair on handgun slide and barrel and can be covered by Cerakote?
Another candidate is Devcon 10760 Titanium Putty
I mean filling a small dent or gap.

None. It will chip off.

Tig, Micro or Laser weld is what you are looking for.
After filling, dress the surface back to flush and Ceracoat.

Lol Bubba-weld?

How about Devcon 10760 Titanium Putty?
Somebody used it for beding riffles and also as a pillar bed in the stock.

Which kind of the three is good for barrel?

Micro or Laser are best.
Whichever puts the LEAST heat into the part to get the job done quickly.

It's still just an epoxy.
The vibration of firing will vibrate it loose from the barrel in short order when used to fill a very small scratch/divot.

It works as stock bedding because you have a large amount of it that's mechanically keyed into the stock.

Both are good, Devcon is better but I'm not sure you would want to use them in this application.

Could silver soldering be a low temp alternative to welding?

Bubba fix does not care if it lasts.(LOL) Do it 0nce do it right.

Just for cosmetic repair at my best effort and then have Cerakote over it.
If the epoxy fails, I would not bother again.

Could silver soldering be a low temp alternative to welding?

Yes, but you want soft solder as it's more like 500-600 degree working range than actual silver solder that has a 1200-1300 degree working range.

I use belzona 1221 often at work for fill repairs on million $ equipment when done right it saves $$$$$$$

Stay Brite #8 is soft silver solder, 550*+-
56% silver is for brazing, (1200*)
