What Can a Laser Welding Machine do in a Jewelry Store?

What is laser welding jewelry? Laser welding jewelry is a technique used in the jewelry industry to join metal pieces together. It involves the use of a laser beam to precisely melt and fuse metals, creating a strong and durable bond. The advantages of laser welding in jewelry include its precision, ability to work on various metals, and suitability for repairing or modifying intricate pieces. It is commonly used for tasks such as resizing rings, fixing prongs, and assembling complex designs.

Laser Welding for Jewelry Repair

Jewelry laser welding machines are primarily used for filling hole, spot welding of sand eyes, and repairing gold and silver jewelry. The laser spot welding process is a type of heat conduction, where the laser radiates and heats the surface of the workpiece. The surface heat then diffuses internally through heat conduction, and by controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulses, the workpiece melts, forming a specific molten pool. Due to its unique advantages, it has been successfully applied in the processing of gold and silver jewelry, as well as the welding of micro and small parts.

Adjusting Jewelry Size

Using a jewelry laser welding machine, rings can be easily adjusted to a slightly smaller or larger size.

Re-tilting Prongs and Repairing Settings

Prongs may become loose and often lose their grip on the tip of gemstones in rings. A jewelry laser welding machine can precisely locate the issues in the prongs and help them securely hold onto the gemstones. It can also assist in repairing the setting of ring prongs.

Reassembling Damaged Jewelry

Necklaces, bracelets, earrings, and other jewelry pieces can be easily repaired and reassembled. Whether due to wear, breakage, or other damage, the laser welding machine can finely and reliably restore jewelry, giving it a renewed appearance.

Custom Jewelries Design

Laser welding in the jewelry industry can achieve custom designs or modifying jewelry becomes easy. This allows for meeting customer requirements, whether it’s altering design patterns, adding decorative elements, or adjusting shapes.

Jewelry Laser Welding Machine Parameter Setting

– Laser Power

The appropriate power is selected according to the requirements of the welding material and the welding position. Typically, laser power for metal welding ranges from 40-300 watts. It is necessary to select the appropriate laser power and focal length. In general, the thinner the welding material, the less power and focal length is required.

– Pulse Frequency

Adjusts the number of pulses emitted by the laser beam in one second. Typically, the pulse frequency for welding metals ranges from 1-50 Hz. In general, materials with lower melting points require higher frequency laser pulses.

– Pulse Width

Adjusts the duration of each pulse of the laser beam. Typically, the pulse width for welding metals ranges from 0.1 to 20 milliseconds.

– Spot Size

Adjusts the focal spot size of the laser beam to accommodate different sized welding areas. Adjust the laser spot size and offset according to the shape and density of the weld joint to ensure a strong and beautiful weld joint.

Different jewelry materials and metal types may require different welding parameters. Therefore, it is best to refer to the instruction manual of the corresponding welding machine or go through training on the use of the machine and equipment, and make appropriate parameter adjustments and optimization in practice before carrying out the welding operation.
