Welding required - Blackpool

[ched999uk]

Hi,
hope I am not breaking any forum rules. I have a problem with an accumulator (plumbing water container). Long story but I have 1 last chance at a repair before plan B. Plan B being to get part of it welded together. I believe it's steel (1-2mm thick) and needs a 50mm washer welding onto it. The washer is currently tack welded and I can clean all the pain off but it would be ideal if it could be welded in situ as its a bit heavy and on third floor?
Accumulator:

Welding required:

If it can be welded in situ can any one recommend anyone in the Blackpool area?

Thanks

Braising would probably be best bet. Local plumber should be Abel to braise it no bother

Thanks for that. I can weld but wasn't confident on something that is a bit critical and expensive £800+. I can also braze although it has been a good few years since I did any. I might just see how much a simple torch is and give it a go.
Thanks

why dont u just soft solder it. it would be easy and strong enough

Hmmm Why is it leaking? Is it a bulkhead type fitting with a rubber washer behind it? Because that washer that's just tacked on has never been water tight alone!

You are correct the washers are not water tight and never have been. The bulkhead fitting has a sort of rubber washer behind it. The washer is actually a rubber bladder that contains the water. Between the bladder and the blue vessel you can see in the images above is air. This air pushes the water out of the bladder when the water pressure drops. Basically it maintains water flow when the pipe to the house can't support the demand.
Anyway the rubber washer(bladder) has distorted and so it wont seal. A new bladder is £300 + vat. So I am trying to find a different solution. It is only the air that is leaking or should I say weeping. It runs at about 35psi and I am losing about 0.5psi over 3 or 4 days.
So if I can get the washers welded/brazed/ or soft soldered the leak will be fixed and it will save me money.

Hope that explains it a bit better?

But wont welding/heat melt the bladder?

Yes but I can remove bladder

id go for a good plumbers solder and a propane torch, or a bit of brazing rod, both should work
