It looks great. What is the type of Flux did he use?

I mean (WTF)... what the flux?

Thanks! He did not use any flux. This has been welded, not soldered or brazed.

Weld done!

Ha ha! Thanks, he really did an incredible job.

I found a YouTube sample of the method used. It’s like looking into a microscope with crosshairs on the area you wish to weld. A silicon bronze was used for the rod material on the cymbal.

O.K. so there you are. Flux was used and it was silicone bronze.

You can't just melt the bronze from around the edges of the crack and then hope that it will somehow just magically join the edges together. You need some flux. It ain't gonna happen any other way. Hence the reason why I asked question in the first place.

I don’t think you understand that flux is used as a cleaning or purifying agent. For instance when soldering, flux is typically smeared on first with a small brush (it’s kind of like vasoline or paste consistency) torch heated and then the solder is applied to join and seal the item. Flux paste is used in soldering or brazing.

The silicon bronze, I believe is the welding rod material being fed in which is melted into the area to be welded together. A laser melted it in this case.

I’m not a welder or metallurgist but to my understanding, flux is like a paste applied before soldering or brazing.

I'd did some reading on this subject and you are completely correct sir.

The use of flux for welding is only a temporary requirement. In the not too distant future welders will all use flux capacitors powered by a Mr. Fusion. I assume they will have to accelerate their welding rigs to exactly 88 mph before the weld will stick...

You’re about 1.21 Gigawatts off on that equation but good for a laugh.
