Sonofa! - Pin hole leak in weld..

[aekdbbop]

So after i went through all that trouble of getting my kegs welded, and having to clean them up, it turns out i have a pin hole leak in one of the welds..

so what should i do? I really dont want to make a big fuss about it..

suggestions?

If your welder missed a hole then that is not his problem but if you asked him to weld all the leaks and leak test then he should be glad to fix it. He most likely will fix it no charge if he made reasonable money on the job the first time. I would at least show it to him. Most welders like to please.

 

[RegionalChaos]

take it back, be polite, he'll probably fix it up for you no charge.

either than, or JBweld. Id take it back and ask him to touch it up.

 

[aekdbbop]

i may just jb weld it up.. anyone done this before? ive never used the stuff..

 

[sirsloop]

Its a two party epoxy. mix the grey and white 50/50, spread it on, wait 24 hours. Its great stuff! You could also braise the hole with a rod and a mini propane/mapp gas torch.

Ugh, sorry to see that. Is JB Weld food safe? The problem is adhesion, especially to SS. I have never used JB Weld on SS, nor for food applications. I really don't know what to suggest, other than having a different welder fix the weld.

Ok they claim it is non-toxic and will bond fine to Steel (I didn't specifically see SS though).

I think brazing sounds like a good idea if the welder can't fix it up... JB Weld sounds like trouble...

 

[olllllo]

If you don't allow a business to correct a problem then the business is not bad, you just might be a bad customer.

I used JB weld on a corny with a pinhole leak. No problems. YMMV.

 

[aekdbbop]

any resources on brazing? never thought of it..

Why don't you want to take the keggle back and get it fixed by the welder?

B/c he did a bad job in the first place.

This same thing happened to me with my gas manifold. JB Weld did the trick. I love the stuff.

 

[BarleyWater]

JB Weld is your friend. Use it, love it.

Come on guys, this is brewing and we should not use any bunch of chemicals (JB Weld) that will leach into the brew. I suggest finding a good quality weld shop that knows how to make proper welds on stainless with shielding gas on both sides of the weld. Mickey mousing things is just BAD.

 

[Grimsawyer]

Silversolder the thing! If you have sweated copper you have 1/3 the materials you need. (note, I havn't silver soldered yet. I plan on doing it soon... as soon as I have money for the !@#$!@#$!@#$ solder. It's not cheap, but it's SWEET!!!)

My understanding is that once cured there is no leeching and no toxicity. Your point is well taken though; I got rid of all my Teflon pans years ago for the same reason. Here are the MSDS sheets for the two part epoxy.

+1 on silver solder

 

[reidstav]

If it's just a pin hole leak, then you can "ping" it.
Use a sharp tipped punch. Set it just to the side of the pin hole and hit the punch, with a hammer, back toward the pin hole. It may take a couple of hits to seal the leak.

This is why I go weldless... $16 from morebeer and it is done without leaks and fuss. I know I know, some of yall swear by welding... but I converted 3 kegs for under $50 and they don't leak, took all of 15 minutes!

 

[aekdbbop]

ok, i havent gotten this fixed yet.. but i was looking at using some lead free solder on the hole.. it has a melting point of 450f.. would that work?

 

[aekdbbop]

anyone????

 

[MikeFlynn74]

JB weld might as well be steel. Its so hard it can be machined. I used it once to plug a pinhole Gasoline leak, while it was leaking!

Id use it and fuggedaboutit

 

[BrewSapiens]

If it's just a pin hole you could use food grade silicone to plug the hole. Then you could relax on all the "wierd chemicals leachin' into my brew".

My $0.02

 

[aekdbbop]

is that silicone hi temp? where can i find stuff like that?

 

[conpewter]

I'd probably go the silver solder route if I already had the propane torch, otherwise JB weld, that stuff can fix an engine block.

As for silicone, it can stand fairly high temps
