Type of weld for AK muzzle break?

i would say take it off because one day you might shoot and ........ bad picture. take it off and port it you will have a nice SBR knock off and get a duracoat in your favorite aqua color.

file your paper work right away chief so you can have a SBR and silencer for it. class 2

FYI, it's a muzzle brake, not a muzzle break (although it is both now, haha).


I would say any decent welder or gunsmith should be able to take care of it for you.

you need to be careful of heat build up in the barrel when you weld. You can make a heat sink out of a pair of vise grip pliers, just attach them just beyond where you are welding. You'll want a "Full penetration" weld. The weld you have was likely done with insufficient power and did not actually mix the metal. This would best be done by a 220v or higher welder. To do a really good job of it you could drill a small intent into the barrel and muzzle device, then fill the depression with the new weld. (Similar to how a fillet weld) This will make it look better and also impossible to turn out. You probably do not want to make a solid weld, just a better spot weld or 2. If you do 2 let the metal cool fully before doing the second. Weld quickly and limit the amount of heat put into the gun. I've not done this to a gun, but as a construction manager, I have had to deal with certified welds and x-ray inspections, and have learned a little about welding & metal work.

If that muzzle brake is threaded on, it may be okay to just leave it as is and check it now and then.

For a proper weld job, I'd say go find someone who's skilled with a TIG welder; he can put a good weld in place without applying so much heat as to risk damaging anything else. He may want to preheat the area a little, and it will have to be as clean as you can get it. You can grind off the old weld (which is pretty ugly) and a good operator will make the new one look much nicer.

Kind of a double entendre. The man's muzzle brake has a break.

Yup, what heron said, I could tig that & make it look real good

TIG is your only good choice for the job. If you remove the brake and grind/file away at the old weld you can make the new one flush, paint over it, and never know it's there.

Hogwarsh, ye got ta put summa that ol' JB Weld on it, fix it up real nice.

If its not threaded on what is holding it on since the weld is broken?
