Laser dross removal seems more difficult if delayed

June 30, 2013

Q. Hi,

I have an ultrasonic pickling process to remove laser cut dross from spiral cut tubes.

I have noticed that if parts are left queuing for longer than normal prior to pickling it can be more difficult to remove the dross.
I would be interested from a metallurgical point of view what happens dross with time
which makes it more difficult to remove?
