A leak in the bathroom, a copper pipe to be soldered: crack out the blowtorch and you're all set! Brazing, soldering, copper, silver, surface stripper, welding screens... Follow the guide to get you up to scratch!

Important features

  • Soft soldering
  • Hard soldering (brazing)
  • Copper brazing
  • Silver brazing

What's a welding screen for?

ManoMano
If you're welding near a painted wall, a semi-rigid heat shield is required to cover the surrounding area and protect it from the torch flame.

The heat shield won't be asbestos or ceramic, you can count on that!

Heat shields are also known by various other names, such as thermal screen or flame guard.

Which type of rod for which use?

ManoMano

Different types of filler metal for different applications

  • Soft soldering (under 450°): uses silver / tin alloy rods.

For soldering copper pipes: joint is achieved via capillary action.

  • Hard soldering or brazing over 450°: alloy of brass, copper and a small amount of zinc. Potential for soldering fine metal sheet.

Possibility of brazing thin sheets.

  • Copper brazing: Copper and phosphorus / brass alloy; less expensive types of welding rods usable at melting temperatures of 900–1200° require an oxygen-acetylene torch or one running on propane as plumbers use.
  • Silver brazing: Silver / copper phosphorus alloy required for gas piping.

Which stripper (or flux) for which use?

ManoMano
Before any welding task, surfaces have to be stripped - according to the type of welding:

  • Liquid stripper - to be brushed onto the welding surfaces;
  • Powder flux - the welding rod is heated slightly and dipped in the pot of powder before starting the weld;
  • Welding paste - spread on the welding surfaces and rod.
 
There's a whole range of flows suited to different metals and welding types.

Problems with your torch?...

ManoMano
For various reasons the nozzle of your blowtorch may become dirty. In these cases we use a handy little gadget - a blowtorch reamer. Designed just like a Swiss army knife, a dozen calibrated rods of different thicknesses and a file let you clean the nozzle. Why not keep it in your pocket for easy access!

Am I all ready to get started?

Once the surrounding area is protected, you've chosen your filler metal, stripped the welding surfaces and your nozzle is spick and span, you can get welding!

I was trained as a pipe worker and welder and worked in the industry for 15 years, going all over the UK for large-scale projects. When I decided it was time to stay closer to home - to have time for my own DIY - I took over a local metal shop and eventually went on to become head of a professional engineering firm.

I'm retired now, but I haven't stopped working with my hands. I recently built my own metalwork studio at home - a lifelong dream! I use my welding skills to make sculptures and bespoke furniture. With my studio, I managed to find a piece of paradise where I can let my imagination run wild.

I also love going around to local auctions and boot sales. I always find some interesting old object or tools that I can add to my collection or transform into works of art.

Now that I have the time, I've turned my hand to decorating, painting on canvas and gardening. I'm always developing new technologies and tools to bring my ideas to life. And I'm always happy to give others advice on how they can make their dreams a reality, too!
