Part 3 - Silver ring join

Timeline
Laser Settings and Preparation:
The video begins by establishing the appropriate power setting for the laser, emphasizing that silver requires more heat and technique than gold due to its heat conductivity \[00:26].
The laser's power is adjusted incrementally until the desired action is achieved, ensuring the spot size is minimized \[00:50].
Joining Process:
The process involves holding the joint in position and applying one or two initial laser shots to secure it \[01:07].
Additional wire is then offered into the groove, and the filling process begins, ensuring the material is melted in thoroughly to avoid air pockets \[01:57].
Technique and Flux:
A black marker pen is used as a flux to aid in the melting process, which significantly improves the melt quality, especially with silver \[02:43]. Adjustments to the laser power are made as needed, noting that a "splat" sound indicates the heat is too high \[03:40].
Surface Awareness:
The video highlights the importance of surface condition, explaining that shiny surfaces react differently to the laser compared to surfaces with carbon residue \[04:41].
Finishing Touches:
The joint is tidied up by increasing the spot size slightly \[05:22].
Any residue from the black marker is not a concern as it can be easily sanded and polished off \[05:36].
