Initial Attachment: Begin by attaching one side of the new gold section to the existing ring shank using a low power setting on the laser welder [00:28].
Second Side Attachment: Join the other side of the new section to the shank, ensuring a close and even fit [00:56].
Use pliers to adjust and align the levels if necessary [01:11].
Infilling: Use 9 karat gold wire to infill the gap between the new section and the shank [01:30].
Pay close attention to avoid creating any pockets, as these can weaken the joint [02:19].
If a pocket is suspected, file the area and refill it [02:40].
Material Addition: Add material until it slightly exceeds the surface level of the ring [02:55].
Ensure the sides maintain the correct shank thickness by adding material as needed [03:34].
Inside Treatment: Use the laser to treat the inside of the ring, adding more material if necessary to ensure a smooth and strong join [03:53].
Smoothing: Slightly increase the laser spot size to smooth the surface of the added material, creating a seamless finish [04:18].
Strength Test: Test the strength of the join by gently tapping the ring, demonstrating the durability of the laser weld [04:38].
Final Check: Observe the integrity of the join after resizing, noting that it remains strong without the need for annealing [05:11].

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].

M4 Airpockets
In this video, we cover a crucial tip to avoid weakening your work when welding. One of the most important things to remember is not to leave a "pocket"—a small gap formed as you melt the material. If you move past it without properly filling it in, it can create a weak point that may eventually ...

Laser vs flame
Using a laser welder instead of a flame for jewellery because it offers greater precision and control, reducing the risk of damaging delicate pieces and gemtones. Laser welding also produces cleaner welds, requiring less polishing and post-weld cleaning.
