Welding a moderator

This has a really simple and sensible answer, buy a bloody new one.
It's a moderator, filthy dirty inside, so not much chance of a decent weld anyway, not to mention
It's a moderator, a consumable item, buy a new one.

Not picking but would you bin £ 200 tyre with a small nail in the middle of it or have it fixed......?

Have you ever had a tyre fixed?

As a metalworker I would want to look at the actual thing rather than a grainy photograph to see whether starting from its current state I could weld it any better than they did in the factory conditions starting from new.

As a consumer I would be ticked off that somebody would supply something that was not up to the job.

Your analogy of the tyre repair would be better matched if it was a tyre with a weakness that was a result of poor manufacture, rather than after-market-nail damage. If the tyre leaked air because of bad manufacture would you be happy to have it repaired or prefer/expect to have it swapped for a new/good one?

As a toolmaker/fabricator my self, making an affective repair is quite often the only option with things people have that come through the door, you can chuck anything away as you know.

However the " small holes in a moderator " would be something similar to a small hole in a tyre left by a nail....

One of the other points made some time back in the dark ages of this thread was brazing or silver soldering was not and effective method of repair...!

I don't know of any English made guns that are not manufactured using those processes...!

I will lay good money there are very few people on this forum that have not had a tyre fixed with a puncture in it..... a new one might be only half the price of a new mod but they would have it fixed...


Get a new one no prob, but most have joined the millions who have neither the skill base, experience, inclination, nor gonads to fix things.....but don't knock the people who can.

My point was not the similarity of the damage, but the cause of it.

If the tyre or moderator was not 100% from new that is something that the manufacturer should put right.

If the damage was caused by a nail, or bad owner maintenance, or other cause that was out of control of the maker, then the issue of how or whether to repair comes down to the owner...

It looks like a bad weld in the photograph don't you think? The maker should at least be made aware of it and have the opportunity to put it right or replace.

:rofl: , what a lot of chat over a **** welding job looks to not have gained any penetration at time of manufacture pos by a robot ? just weld it and bugger all will happen or send it back job done :doh: welded lots of T8's Due to them rusting never had a bullet clip the baffles but then iam not a DIY welder lol.



The Americans spent a $1000000.00 on a pen to write in space....the Russians used a pencil....

Just get a competent welder to weld what looks to be a **** job in the first place, clean excess off, spray it matt black, then make it post "69" and enjoy. deerwarden

Hardly the same thing is it.
But as you asked, if a small nail is in the tread block, then yes I have had one fixed, all others have been between blocks so binned.
Motorcycle tires, I used to carry a plug kit, yes they work, and have always got me home, but I'd not push it any further.

your right but with my limited knowledge of best gun making I think they only silver solder the rib on and join the barrels no pressure bearing parts are sealed with silver solder?

I can tell you one thing for sure and that if the moderator was mine I wouldn't be welding it. That's because my arc welding normally turns into arc cutting.:lol:

Seriously though I am wondering if most sport shooters need to re-consider how long they keep a centrefire sound moderator. Should we be more realistic and consider them more of a consumable item that has a limited service life rather than something like a rifle which can possibly last most amateur stalkers a lifetime. I realise that there are some moderators that are far more resilient than others but I believe that the FC only keep their T8 moderators for 2 years or a certain number of rounds before replacing them for reasons of safety.
 
I cannot believe a moderator repair keeping tons of pressure in could be compared with a tyre keeping 30psi inside.
 
Low pressure/high volume. I have seen 2 7/8" oilfield production tubing blow at 12,000psi and it makes a tyre blowout seem like a boil being lanced.
 
Luv to keep stuff going, ... I reiterate, Bronze welds go up to 70,000 p.s.i.:stir:

OH, & funny how a barrel starts off soooo big, then that lidddle biddy thin bit down the end, with that great big spacious can on the end.:cool:, .. come on Tim!
