I spotted this in a welding forum.....it got me thinking... a big problem welding cymbals is when you heat the metal brass and alloy mix it becomes brittle as the molecules in the metal change...
the big problem welding cymbals is also they are normally not one type of metal they are a combination of many Brass,Tin, copper, zinc. phosphorus, bronze (bell metal), nickel bronze, manganese,silicon, aluminium bronzes, silver,gold

I was giving some thought of how to bind two metals together without using any heat or welding wires/rods and an idea struck me. Seeing that the atoms are similar to each other why not excite them using a frequency that would be applied to make them energetic enough to just bond together? If a sound frequency could be found that could make the atoms so energetic couldn't this actually be done? Just a thought, what's your thinking along this line?

Sonic fusing is a common way to join plastics. They probably do it for metals too, but metals do this naturally. Perfectly clean metals will fuse to each other instantly.

Any kind of energy that will heat the metal up will work. Sound energy is as good as anything. "energetic" is the same as heat.

Microwaves?

So why not use electromagnets to attach the device onto the pieces that need to be fused together and leave it without anyone around it until its done with its job?

Sonic welding has been done on aluminum since the 1960's. They have also tried it for steel, although you need to heat it up a certain degree.

It shows much promise. You might be able to clear a free surface by abrading in oil or a nonreactive liquid, then applying ultrasound to assist the free energy spontaneous bonding in metals.

I maintain that metal will weld with each other with no added heat if the mating surfaces are perfect, and there is no oxidation. I used to work at a company that produced a cold-welded material for dental fillings. The material was just a kind of metal with a coating of copper. It's easy to remove the oxidation from the copper with an activating solution, after which the metal particles naturally weld to each other.

A film of oxidation or foreign material is the only reason metals don't weld to each other when touching.


It's easier to do for low- metals like dental amalgams, solder, tin, aluminum, and even brass, but much harder to do for other metals such as iron and titanium.

You have to heat close to the creep temperature (roughly ) to successfully use ultrasound welding on them. Solder creeps at room temperature, and aluminum can creep at around the boiling point of water.

I was thinking more on the level of molecular steel. We used it in power houses to patch up boiler leaks. Kind of an epoxy based mixture and applied the same way.

I've never tried it with brass due to the oxidation that can cause corrosion. I'm no metals specialist but I do know my science of electrons.

Tis logical, and if it ain't logical it won't work.

Welding is an art in itself and takes many years to accomplish. I've also been to the TWA training academy to learn avionics, aluminum is another animal I learned about. Another industrial art that I would leave for the experts.

Drumming is an art made from love and it's not complicated when you put your mind into it.

K.I.S.S.

There would be great profit to made if it is made possible not just the repairs of cymbals but also for the construction industry...in general.
You would also have to look at if the repair would be commercially viable and not cost more to repair then the product....

Another option would be to recycle cracked cymbals have a scrapage scheme. so when you go to buy a replacement cymbal you hand your old cymbal over and get a discount on the new cymbal....and its just melted back down. Wwith the supplier of the new cymbal....

I have seen cymbals welded by conventional means and its very hit or miss.
The softer metal melts and creeps the hard metal absorbs the heats and you gets runs blow holes and hard glass like smelt that becomes brittle.

Therefore the integrity of the cymbal is lost....Its weighing up the cons...i guess.
The sound waves got me thinking tho......

[Tainojim]

If some people really care about the environment and want to save a few bucks on a cracked cymbal, then it should be taken to a scrap metal yard, get their few bucks and invest it into a new one.

In this manner we can all save the world and save money at the same time. Brass is worth a pretty penny in the recycling industry.

So for those drummers, unless your looking for that certain sound to be creative, stop doing this, and continue doing this .

Tainojim i think we should start a new revolution get the manufactures to recycle and give its customers the hard cash back.....lets start a global save the planet cymbal re-cycle program...

[Tainojim]

Sounds like a great idea, BUT as we all know Industries are only interested in making a fast buck through cheap labor and using cheap materials. The industries would have to put out more money to even start a program like that. It's not feasible for them. And they really don't care.

We can talk about this till we're blue in the face. The bottom line here is that there is still a way to recycle the brass without breaking our ass.

Besides the scrap at the places , the more metals they get, the more jobs can be created and that's a big plus all around. This also give the homeless an little opportunity to make a couple of bucks.

It's a great idea though.

[Pyrochazm]

I rea rlly dig the idea, having just cracked a cymbal meself. But I think it would end up being a lot cheaper just replacing it.

Scrap it dude and get a few bucks for it......................
