Irun lazer welding macines that lazerweld gold wire into jewelry chain but cannot lazer silver wire as the lazer reflects off the material. is there a process that can turn silver black or grey ? if i take a black magic marker and coler the section to be lazered it works. we run wire in volume so i need something to do about 800 grams of .012 wire at one time
You should know every trick in the book, not every body runs wire welding machines or even knows what one does. There are a bunch of things that will color wire, but you might not get the color off. Ferric Chloride, steel ink, liver something? I know the steel ink will come off, the ferric chloride might not, also a potent acid. Used in copper etching. And the liver ? I can't remember what it is called, but it is used to patina silver jewelry. Hope this helps.
Testimonial: "appreciate the feedback. itried the steel ink but the problem is getting it to cover every spot on wire .if it hits an uncovered spot it wont lazer. "
