Silver soldering! How to join thin wall tube and fittings, repair patches and more!

In this video we look at an age old metal joining technique with some Silverflo 55. We join thick to thin steel components, and cover a hole with a small patch that we manufacture from scratch.
We also talk about flux, how to mix, what to look for and generally how to join components.

Good video , very informative 👍🏻

Thank you, glad to hear you found it useful!

I think you need to do a joint project with Snowball Engineering... Yorkshire farication meet up!

Definitely cut from the same cloth! His workshop is far superior to mine though although I’d say I’m slightly warmer in my cosy garage…

Silver solder makes a really solid joint, just a little bit less strength than brazing. It is impressive that you have 55% silver solder, mine is only 25% and it needs a lot of heat to melt, but I only use it for electronics that need to have some physical strength.

It certainly does, a perfect solution for this job. Not too much heat and almost as strong as a weld. I don’t have vast quantities, but they last such a long time a couple of short lengths will likely last me a lifetime! 55% is a great choice for general applications, not the cheapest but it’s really easy to work with. The solder melts at around 650 degrees c, so a dull red colour with most steels, the flux is 600 after checking. No point risking the integrity of the part with welding when this is much more suitable! Hope you enjoyed and thank you for the comment 👍
