How to Prevent Burn-Through When Laser Welding Jewelry
Burn-through is a common challenge in jewelry laser welding, especially when repairing thin gold chains, delicate ring sections, fine prongs, and other small precious-metal components. It occurs when excessive laser energy melts through the workpiece instead of creating a controlled weld. For je...Read more -
Laser Welding Frequency for Gold Jewelry
Laser welding frequency is an important parameter in gold jewelry repair and manufacturing. It determines how many laser pulses are delivered per second, influencing heat accumulation, weld consistency, and the appearance of the finished joint. When repairing gold rings, chains, prongs, and o...Read more -
How Spot Size Affects Jewelry Laser Welding
Spot size is an important parameter in jewelry laser welding because it determines how concentrated the laser energy is on the workpiece. Choosing the right spot size helps jewelers control weld depth, minimize heat damage, and achieve clean, precise repairs on gold, silver, platinum, and other ...Read more -
How to Set Laser Power for Jewelry Welding
Laser power is one of the most important parameters in jewelry laser welding. The correct setting helps jewelers repair broken gold chains, close ring cracks, rebuild worn prongs, and weld delicate silver or platinum components with greater precision. However, there is no single laser power sett...Read more -
Laser Welding Parameters for Platinum Jewelry: A Practical Guide
Laser welding platinum jewelry requires precise control of pulse energy, pulse duration, spot diameter, and frequency. Although platinum has a high melting point, its relatively low thermal diffusivity makes it particularly suitable for localized laser welding when the correct parameters are use...Read more -
Laser Welding Parameters for Silver Jewelry
Laser welding silver jewelry requires precise control of pulse energy, pulse duration, spot size, and frequency. Compared with gold, silver presents unique welding challenges due to its high thermal conductivity and reflectivity. Incorrect settings can lead to incomplete fusion, excessive heat l...Read more -
Jewelry Laser Welding Parameters for Gold: A Practical Guide

How to Reduce Heat-Affected Zones in Mold Laser Welding
Heat control is one of the most important factors in mold laser welding. Injection molds often contain sharp edges, fine cavities, parting lines, inserts, and precision surfaces where excessive heat can cause distortion, discoloration, cracking, or dimensional changes. A pulsed YAG mold laser we...Read more -
Laser Mold Welding Before Polishing: What Happens After Repair?
Laser welding is often only the repair stage of injection mold restoration. After a damaged area has been rebuilt with laser welding, the mold usually still needs machining, grinding, polishing, and dimensional inspection before it can return to production. Understanding what happens after laser...Read more -
How to Repair EDM Damage on Injection Molds with Laser Welding
Electrical discharge machining (EDM) is widely used to produce complex cavities, ribs, sharp corners, and fine details in injection molds.
