Solder for steel
« on: November 17, 2014, 11:28:06 AM »
Hi

I have a Williams Models wagon kit that I will be starting shortly and that will require me to solder steel - something I have not tried before

Can you please suggest a solder suitable for soldering steel - I intend to use Carrs green flux and a 80w soldering iron

Can you please suggest a specific brand and spec if possible

I am going to Warley at the weekend so a model specific solder will be ok if you think it's something I could find at that show

Others will have to advise you what they use (and how they do it) Rob.

The last lot I did, I brazed but silver solder would be similar. I did soft solder some a while ago but still used a small torch to do it. For mild steel I think Carrs 'Green' should do the job OK.

The other thing that I used (but may not work in your case) was two small 'angle' plates cut from scrap steel and tapped to take holding screws. They kept the pieces at right angles whilst I was soldering - but I had plenty of heat. An alternative would be a simple wooden jig (two pieces screwed together to give a right angle) to hold things in place, which would get 'singed' but not draw the heat away too much...

Regards,

IanT

Rob,

I use Carr's green flux and used their "224" solder on my Cliff Barker stainless steel pointwork (with a microflame butane torch) but I believe Carr's 224 is no longer available (wasn't last time I looked at their website).

In the past I have used Templer's Telux flux and Fry's "Powerflow 99c" lead free solder for mild steel to brass (e.g. footplates on GRS loco kits).

Regards,
John

No idea what make of solder I use, but something like this should do the job,

Being a luddite, I don't trust lead-free solders and can't see the pint of them.

Your 80W iron will be more than sufficient and with that flux the solder should rum like water - perfect.

Mike - have you cracked the Christmas sherry open already??
Or maybe sampling the ingredients whilst making the Christmas puds? ;D

Hello Rob and All

If you are soldering the white metal springs to the W irons . My method is to tin the W irons with ordinary solder first and the flux that comes in a yellow tub  ( I use a 75 watt iron ) and then use low melt solder and phosferic ( liquid flux ) for the white metal bits .
