With Rofin laser welder, you can actually weld really fine chain, working on individual links. Doing that the old way, jewelers would chop off part of the chain and solder it together again in a glob. The laser welder is so versatile and useful for fine repair work that it can be used to repair or restore vintage (antique) jewelry. With the laser new things can be done with metals that were impossible before. Pieces that weren't fixable before can be repaired with this. You can smooth things out and create textures and you can even solder two different metals together. Stuff that you were limited to before, now because of the technology, there may be no limit to what you can do.
