Hi, I was wondering if you can use propylene gas for this kind of brazing, as opposed to the acetylene torch that you appear to be handling. please correct me if I'm wrong about which fuel you're using.

@lingd8

I'm using acetylene. I've never used propane. You will just have to give it a try and see if it will do what you want it to do.

It will be slower than acetylene as it is not as hot.

You mention not being able to see. I hear that "tinmantech" has developed a special welding mask lens specific to this operation, that blocks the right wavelengths so as to prevent your corneas being burned out. Sounds cool. I'm curious about the strength of such a joint. I know you're an artist, I wonder whether copper wire would make a suitable brazing material for something structural, such as a bicycle or motorcycle frame. I heard certain brazing is stronger than mig/tig, such as aluminum...

@SoyBoySigh Thanks for the comment. I'll check the mask lens out.

I don't know what the strength factor would be using copper as the filler rod. Today there are so many metallurgical specific rods I'm sure there are filler rods far better than copper wire.

This would be especially true for bicycle and motorcycle frames where a minimum of rod is needed.

Hey George at 2:27 do you recall wich was with flux and without?

On the Left and on the Right?

Also, is this same process possible on Stainless?

Thanks!

@aaronfu2 The part on the left was done with flux.

I've never used the copper wire as a filler wire between two pieces of stainless.

Hey, great vid on metal brazing. I have been researching the past couple of years about metal sculpture so that I can get my style of work out of my head and your vids are a big help.I know asap I will be ordering your DVD, I can't wait.

Excellent vidio and advice, thanks .

@spelunkerd Why braze? I do metal sculpture so the bronze color makes a good contrast with other metals.

I'm not looking for exceptional strength.

Plus, I like to braze

Best plan is to know how to braze, silver solder, gas weld and electric weld. Then choose what's best for a specific application.

[spelunkerd]

When would you want to braze rather than just weld it? It seems as though welding would be faster, with a stronger bond, though i guess you don't have to heat is as much when you braze. I guess you would say that brazing works when metals are dissimilar, but are there other situation where brazing is preferable?
