Guess the weld

[Ltbadd]

Thought I'd give this a shot if anyone is willing. I'll start by posting a picture of a weld, you have to guess the process (and filler if applicable) and if possible the base metal(s). The winner can then post another photo, and so the game continues.

copper tube, brass fittings and silver braze...Bob

That's not a weld. Silphos braze, copper to brass.

Brazing (B)

Brazing is "a group of welding processes which produces coalescence of materials by heating them to a suitable temperature and by using a filler metal, having a liquidus above 450^oC and below the solidus of the base materials. The filler metal is distributed between the closely fitted surfaces of the joint by capillary attraction." A braze is a very special form of weld, the base metal is theoretically not melted. There are seven popular different processes within the brazing group. The source of heat differs among the processes. Braze welding relates to welding processes using brass or bronze filler metal, where the filler metal is not distributed by capillary action.

Soldering (S)

Soldering is "a group of joining processes which produces coalescence of materials by heating them to a suitable temperature and by using a filler metal having a liquidus not exceeding 450 ^oC (840 ^oF) and below the solidus of the base materials. The filler metal is distributed between the closely fitted surfaces of the joint by capillary attraction." There are a number of different soldering processes and methods.



According to AWS, Brazing, Soldering, Resistance, Arc welding, ETC all fall into the category of "welding processes"

i would call that silver soldering. clean pipe ends put on flux then heat it enough so the silver solder gets sucked into the pipe and fitting.

After further research, I concede

concede what?

I work for a guy that refers to Silver soldering as Welding. It bugs the
crap out of me.
I think of welding as joining two like metals together with a filler of the same.
Brazing and soldering never fit into that category.

I ended up learning from your post that welding does not exclude soldering and brazing from the group of 'welding processes'

I learned something as well. And I cant get so irritated when the boss refers to silver soldering as 'welding'

I am a welder and welding has made me a better brazer and solderer. I can't say the same for those that know how to solder or braze exclusively..

30 years ago i was a union sheet metal worker in a large shop. Some days i welded and some days i soldered screen onto perforated weldments. Move ahead 30 years i now silver solder once or twice a week putting brass radiator necks onto steel tanks. I didn't think of it as welding but i have never read every welding book or pamphlet either, it was just part of my job...Bob

As the definition states, brazing and soldering is a "welding process". Without knowing how it's defined (a weld), one could easily presume it (a braze or solder)would be defined as a weld, at least I did.

Ok
Now that we're all on the same page.....I believe the ball was thrown in your court (to post a pic of the weld of your choice) for guessing the process correctly.
That is before we shook out all the particulars about process definition.

[Helios]

My understanding is, if the base metal melts and mixes with the filler, it's welding.

If not, it ain't.

Well AWS says if some part of it melts, it's a 'welding process", which is what the OP was requesting we guess.

Could be plastic (non-metallic)

Personally I don't have any peculiar weld process pictures I can post. I few years back I learned how to forge weld, and I have a feeling that would be a hard one to figure out.( if I had a picture to post)
