Annealing
« on: October 17, 2018, 02:23:19 PM »
.I was working with a couple of highly trained (heating engineers) today and their pipe bender broke , we are in the middle of nowhere and have to get finished.They are getting jumpy coz they might have to work late.No problem I say we will anneal pipe and bend by hand.They both look at me like I am a space alien.To some of you it is simples but to others here is process you heat to a cherry red colour and drop into cold water.simples😏a great way to ressurect old copper head gaskets for re- use 😀😀

Copper doesn't have to be dropped into cold water after heating, but it's quicker than waiting for it to cool in air.

Interesting, never knew that it was the way I was taught but as in everything there are numerous ways of completing the same task😏

Dropping it in water helps to get some of the black sooty stuff off it after annealing

Moons back.
I started metal class at Forces brat school in Germany. The exercise was to cut out a disc of copper and then beat on a stake to create a bowl.
The teacher got us after every 1/2 hour to anneal (due to work hardening)and cool under tap but stated allowing to cool slowly was better as the annealing would be more uniform. It was only when I got home and mentioned this to my Dad that I discovered he had been trained as Copper-smith in RAF. Shows what you don't know about your own family!
