Are cold shuts repairable and does anyone have examples?

[milandro]

I was discussing this with some people I know and I have researched this topic on the forum finding some very general information but not much in the manner of whether it is possible to deal with them.

I don't know much about forging but what I have seen on TV is that when attempting to make a blade with a damascus pattern, therefore putting together different types of steel, it is not uncommon to produce a cold shut if and when different metals react differently with temperatures that are too low and therefore they don't weld well together leaving a " crack" or rather an area where two parts aren't forged together.

Sometimes these cracks are deep and are through and through as in some combong krises.

Sometimes the crack is undeep and therefore it can be ground until one reaches solid metal .

But someone here talked about the possibility for the empu to either reforge the blade and trying to close the " crack" or to add metal ( this last procedure was frowned upon if I recall correctly).

Any experience? Any pictures of before and after that anyone is willing to share?


Thanks.


there is a thread

here there are some considerations about ANAK SUNGAI



I have seen krises called Anak Sungai offered for sale and some are clearly the product of a forging cold shut , the fact that the empu sells the blade anyway is supposed to show that he couldn't efficaciously deal with this and claims a special talismanic property to sell the blade anyway?
