Brazing Ss

[spg]

I've managed to crack one of the welds on my RH stainless tank (tring to bend the seems out to fit round / clear the two back down tubes)

Anybody out there got any experiance of brazing / silver soldiering on stainless steel.

[Guest Kieran]

It would be easy enough to simply tig it.

 

If you have acces to a tig I suppose....

I had a similar problem and took mine to a local stainless fabricator who did it for around a fiver. Their main concern is if the tank has had fuel in it Health and Safety issues and regs. come into play.

spg,

 

I have silver soldered other types of stainless before and it works ok.... you need decent quality solder and flux tho'

 

There is a 'soft' silver solder paste available that will work and needs a lot less heat, [a bit of pre-heat to tank and large soldering iron...] but it is expensive!!

 

Like the other Guys say rewelding with TIG is probably the best answer

 

Another possibility is the POR 15 fuel tank kit... basically a paint type coating for the inside of the tank, vintage and classic Guys use it a bit I think... no idea what its like tho'

ive had a go, need good flux and you can get brazing rods and torch from b&q. good results so far...?

[spg]

Guys love to buy a tig set but can't justify for a small hole, They cost a load of beer tokens.

Bloke did you use standard brazing rod

[Guest bloke]

b&q do a flux coated silver solder. need to use seperate flux on the ss aswell

 

care needed as the heat can distort the metal but if i did it ne1 could - brazed a swirl pot to the bottom of my tank and it seems ok - also brazed the cwing brackets together...

 

drop me a line if you want to discuss further

[spg]

Cheers Bloke I'll give it a go.

Like the swirl pot idea.

[Guest Jim Poole]

I did the same. Silver soldered an outlet to the bottom and vent to the top of my RH tank. I used the blue coloured flux 'silver solder' from B&Q and a MAPP gas torch. The tank distorted a bit when heated but when it cooled it returned back to shape. Was dead easy.

[Guest Russler]

where are you, if it helps I have a TIG welder.

[spg]

Cheers Russler but i'm in South Manchester

[Guest Russler]

offer stands if you are down this way sometime

[spg]

Bloke

What did you use for a swirl pot, Do you have any pics

 

Cheers

[Guest bloke]

spg, have mailed you

[Guest mickmellors]

Steve (SPG) - I have just checked your profile and you dont say where in the country you are so I am not sure if I am near enough to help you.

 

If the tank has not had petrol in it you should not have too much trouble finding a local garage or small engineering workshop/unit with a tig set.

 

If it has had petrol in - please give 24 hours notice before you start welding so I can listen out for the bang !!!!!!
