Soldering Terne coated stainless?


#1

What is the right type of flux and solder to use with TCS? Thanks, Ron


#2

Old TCS or New?

The new TCS has a tin/zinc coating. Use tin solder and rosin flux.

You can use 50/50,tin/lead, on the old style.

Make sure you clean the seams to be soldered. They have a factory finish coating. Laquer thinner works good.

Hi Dennis, New Tcs, just picked it up,Where can I find Tin solder? also should I use emery cloth before the laq.thinner or just the thinner to clean the seam ,I also will pre-tin the hemmed joints before I solder.I have liquid rosin flux is that okay?..Thanks for the info… Ron


#4

ruby fluid or paste


#5

No need for emery cloth.

I get my solder from either Oakland Metal Sales, or McMaster-Carr Supply. Both on the web.

liquid flux is fine

You might want to check with the TCS manufacturer to see if they have any other requirements.

Thanks-One more ? what % of Tin/lead – 50/50 or 63/37 ect… Ron


#7

Depends. If you are at all concerned with the lead environmental and litigation issue. Use 97% tin.

60/40 will be easier and make a stronger seam.

Be sure to allow for expansion joints if needed.

While on the subject of soldering. I need a couple of galvanized skylight flashings and was thinking about soldering them myself. I’ve got a plumbers torch for copper pipe and was wondering if I can use it instead of a soldering iron? Will the galvanized flashing material get damaged from a maap torch? What kind of solder and flux would be proper for galvanized and torch soldering?


#9

For galvanized.
Muriatic acid, 60/40 solder.


#10

we have always used well heated irons. a torch will most likley not make a good joint. It does take a bit of practice especially vertical soldering in the field.


#11

That would be called brazing.

Make sure you neutralize the muriatic afterwards, and it doesn’t hurt to spray it with WD40 once acid has been neutralized.
