Soldering Terne coated stainless?

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

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

ruby fluid or paste

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

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?

For galvanized.
Muriatic acid, 60/40 solder.

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.

That would be called brazing.


For galvanized.
Muriatic acid, 60/40 solder.[/quote]

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

Do you really need to post this link on every single thread ? It was a little bit funny I will admit.

Hey Dennis, I drove to Follansbee’s plant,only 1hr, they say to use: laq.thinner-97%tin solder-zinc choloride for the flux…picked up the materials will give them a try tomorrow…thanks again. ron- slateworks rfg.

Spell Check: Zinc Chloride
