Brass to Stainless

byumetalman · Fri May 26, 2017 5:39 pm

Hey Everyone. I have been tasked with welding a floor mounted door stop to a stainless steel plate. The problem is that the door stop seems to be coated brass or bronze (found out the hard way)? I am not exactly sure how to do this. I tried using a tig rod we have called arc braze 157 t. We have used this on cast repairs and it works for that but not this. I then decided to silver solder it which works but is taking longer than anticipated. The ss plate is 3"x 4" x .120" and the base of the door stop is about .25". I will try and get some pics, but any advice would be great. Thanks

it seems you got the job done, or are there more? If so how many?

19 more to go.

Use a silver braze rod or wire that's 45% silver or higher. I've tiged on several brass and copper fittings to ss heat exchangers for refrigeration systems. The high silver will wet into the ss just before it does the brass. If it's heavy brass consider preheating it a little before you start.

I will try that. Can't remember what my silver braze is. I will check that though. The ss did wet before the brass. How much of a preheat? Brass and brazing are not my strong suit.

Too hot to touch. Some brass casting will give you pin holes matter how you braze it. If it does, and the holes bother you just grind them out a little bit and go back over them like you would with any other weld.

Josh, I think the brazing force is strong with you, you should post more of your work, I know I'd like to see it.

A lot of what I do is in places where you are in allowed to take pictures.

And for comeback purposes: I believe he means "are NOT allowed." I'm sorry I figured that I would take the opportunity

Yup that's what I meant. Thanks.

Are you preheating? Or just focusing your heat and dialing in your settings.

Took your advice and pre heated. It took a while to fine tune my flame and keep the flow right.

Nicely done!

Hey, byumetalman,

I work right next to Bayou Metal Supply's Slidell, LA location. That company name isn't the source of your username, is it?

No it is not. I work for a university in Utah.

Ah, Brigham Young...

You can see where Bayou Metal and byumetal seemed to match, I'm sure.

My mistake.

No worries. I did see that. Wouldn't mind visiting the bayou and meeting another forum member.

Those are looking pretty good. I like the third one from the left best.
