Repairing an emerald and diamond bracelet using laser technology

|Piece of broken top rail attached to center head is beveled to make a channel to laser full with gold wire. The joint is tacked with laser on bottom.|
|The entire joint is welded from one side without adding wire, at the bottom of the bevel to achieve full penetration with the weld. The next weld seam will include added wire to start filling the channel. Additional weld joints with wire will be added with the laser until the original thickness of the joint is achieved.|
|The back of the joint has one layer of weld added because the bevel was cut on the other side of the joint where it had easier access for filling, trimming, and polishing. After the one layer is added the beam is widened and the joint is smoothed out and polished with the laser in the hard to reach area.|
|Now that the joint is completely filled the outside seam is now smoothed and polished with the laser.|

|Completed repair. The bracelet is left with slight wear still apparent so not to ruin the antique appeal.|
|Broken pieces of matching emerald and diamond earring. The broken post shows where the old solder joint failed.|
|Solder is ground offand a deep "V" is ground on the end to be filled with solid wire during laser welding. With the "V" coming to a point, the seam can be welded with full penetration from one side and can be verifiedvisually.|
|Old post is tacked in place with the laser. After correct position is verified and any adjustments made the other side of the joint is inspected to verified full laserpenetration. The joint is now welded from both sides assuring full penetration in a solid joint.|
