How you go about it depends on what you are doing, I used to soft solder brass fittings into stainless header tanks using a oxy acetylene torch and a soft flame, you'll need some blowpipe solder type K and we used Bakers no. 3 soldering fluid flux applied with a small paste brush.
Sheet joints we used to use an old fashioned copper iron heated in a benchtop furnace, but it'll need to be a big one to get the heat into the job.

[optima21]

if you do end up silver soldering tenacity no. 5 flux will work

Take it somewhere and get it silver soldered, its a 10 minute job and would you cost more in getting set up to do it yourself than the job is worth.

Always good to have extra kit though

Plumbers blowtorch (mapp gas) plus the solder/ flux will probably set you back best part of £80.00) better of subbing the soldering out, until you get a job you can include/lay off some of the cost of a blowtorch against

Have a new tracpipe made up.
If the existing has failed, then it will continue to fail.

it didnt fail i broke it heavy handed!

who makes them up

 

[DrDeAtH]

Tracpipe can be made up by your own fair hand, unless it's carrying gas. Plenty of YouTube video on the subject.
