High Welding Precision The laser spot enables precise focusing and can achieve 0.1mm-level micro-area welding, ideal for repairing ultra-fine parts such as jewelry prongs, tiny cracks, and pinholes.

Minimal Heat-Affected Zone Only the welding spot is locally melted, with no deformation or discoloration to the surrounding base metal — effectively protecting fragile inlaid accessories like diamonds, gemstones, and pearls.

Attractive & Durable Weld Spots Smooth weld seams and tiny weld spots mean minimal post-weld grinding and polishing is required, reducing production steps, improving processing efficiency, and preserving the aesthetic finish of jewelry pieces.

Easy Operation A digital parameter adjustment panel allows one-click control of pulse width, energy, and frequency. Built-in memory storage for frequently used welding parameters means even novice operators can master the machine quickly.

Wide Material Compatibility Capable of welding gold, silver, platinum, palladium, copper and their alloys, as well as small metal fittings made of stainless steel and titanium alloy.

• Jewelry Repair — Pinhole mending, crack welding, prong restoration, broken chain splicing, and ring resizing welding for worn jewelry
• Custom Jewelry Making — Precise welding for personalized, custom pieces, meeting the needs of niche and special-shaped designs
• Precision Welding for Related Products — Welding of micro heat-sensitive parts such as precious metal watch components, small precious metal crafts, and denture bases

Frequently Asked Questions 

Q1: What metals can this jewelry spot welder work with? A: The machine is compatible with gold, silver, platinum, palladium, copper, and their alloys, as well as small stainless steel and titanium alloy fittings — covering the vast majority of materials used in fine jewelry manufacturing and repair.

Q2: Will laser spot welding damage gemstones or pearls set in the jewelry piece? A: No. Because the heat-affected zone is extremely small and heat is tightly localized to the weld spot, surrounding materials — including diamonds, gemstones, and pearls — remain unaffected by heat or discoloration, making it safe for repairing set jewelry.

Q3: What does the CCD system do, and why is it useful? A: The CCD large-screen imaging system magnifies the work area on a monitor, allowing the operator to see fine details clearly and position the laser spot with high accuracy (±0.02mm). This is especially valuable for micro-repairs like prong tips, hairline cracks, and pinholes.

Q4: Is this machine suitable for a small repair shop, or only large factories? A: Both. The cabinet-type CCD design is common in jewelry manufacturing factories for high-volume production, but its intuitive digital controls and parameter memory function also make it practical and efficient for small to mid-sized jewelry repair shops.

Q5: How much training does an operator need? A: The machine features a digital control panel with one-click adjustment of pulse width, energy, and frequency, plus a memory function for saved settings. Most operators can become proficient after a short training period, even without prior laser welding experience.

Q6: What is the positioning accuracy and welding precision of this machine? A: The machine offers positioning accuracy of ±0.02mm and can perform 0.1mm-level micro-area welding, meeting the demands of fine jewelry repair such as prong restoration and pinhole mending.

Q7: Does the weld spot need extensive polishing afterward? A: No. The machine produces smooth, tiny weld spots that require minimal post-weld grinding and polishing, which reduces production time and helps preserve the original finish and aesthetic of the jewelry piece.

Q8: What is the power supply requirement, and what laser source does it use? A: The machine runs on a 220V/50Hz/30A power supply and uses an ND:YAG laser source with a maximum power of 300W and pulse energy of 160-180mJ.

Q9: What warranty is provided on the machine? A: Core components are covered by a 2-year warranty, giving buyers confidence in long-term reliability for daily production or repair-shop use.

Q10: Can this machine be used for applications beyond jewelry, such as watch parts or small crafts? A: Yes. Beyond jewelry manufacturing and repair, the machine is also suitable for precision welding of micro heat-sensitive parts, including precious metal watch accessories, small precious metal crafts, and denture bases.
