Jewelry laser welding machine

A jewelry laser welding machine (jewelry spot welding machine) is a high-precision device designed specifically for jewelry, watches, and precision metal processing. It utilizes high-energy laser pulses to achieve instantaneous melting and welding. It features a small heat-affected zone, aesthetically pleasing welds, and no deformation. It is widely used for filling holes, connecting prongs, and repairing seams in gold, silver, platinum, and other karat gold jewelry. It is typically equipped with a microscope for auxiliary positioning.

Typical Applications

1. Spot welding and filling of pinholes in gold and silver jewelry

2. Repairing cracks and breaks in rings and necklaces

3. Securely connecting prongs in jewelry settings

4. Connecting eyeglass frames and other delicate parts

This equipment not only improves the efficiency and precision of jewelry processing, but is also particularly suitable for the customization and repair of high-value, exquisite jewelry.

control system.

Welding control system

This multi-functional welding machine combines welding, cutting, cleaning, and rust removal in one unit. It features an integrated full-touchscreen interface with a sensitive touchscreen and intelligent control system for convenient and quick operation. Touchscreen operation allows for easy adjustment of laser power, weld width, welding frequency, welding type, and language settings..

Laser Welding System
Microscope

Main configuration.

Microscope system

The microscope system is an essential component of a jewelry laser welding machine. It allows operators to clearly observe extremely small welding areas, ensuring precise positioning and high-quality welding results. Since jewelry pieces such as rings, chains, prongs, and small metal parts require micro-level accuracy, the microscope helps technicians perform delicate welding operations that are difficult to achieve with the naked eye.

During the welding process, the operator views the workpiece through the microscope while controlling the laser pulse with a foot pedal. The optical system is designed so that the microscope viewing axis is aligned with the laser beam, meaning the point you see through the microscope is exactly where the laser is applied. This coaxial design ensures accurate targeting and consistent welding quality.

1、High-Precision Optical Observation

Jewelry laser welders are typically equipped with a 10× binocular microscope, which provides a clear and magnified view of the welding area. This allows operators to detect tiny cracks, gaps, or defects in precious metal jewelry such as gold, silver, platinum, and titanium.

2、Binocular Design for Comfortable Operation

The binocular structure offers a natural stereoscopic view, helping operators judge depth and welding position more accurately. It also reduces eye fatigue during long working sessions, making it suitable for jewelry workshops and repair studios.

3、Adjustable Focus and Viewing Distance

The microscope system usually features adjustable focus and working distance. Operators can easily adapt the focus to different jewelry sizes and shapes, ensuring clear visibility of intricate parts such as prongs, clasps, or thin chains.

4、High-Quality Optical Lenses

Professional optical lenses with high light transmission deliver bright and sharp images. This ensures that even very small welding points remain clearly visible, allowing precise and controlled welding.

5、Optional CCD Camera System

Optional CCD camera and display screen. This allows the microscope image to be shown on a monitor, which is helpful for training, demonstrations, and long working hours.

YAG laser

Main configuration.

Nd:YAG laser

A laser is a laser that uses Nd:YAG (neodymium-doped yttrium aluminum garnet) crystal as the working medium. Energy is typically supplied to the laser crystal via a xenon lamp or semiconductor pump, causing stimulated emission of neodymium ions within the crystal, thus generating laser output. In pulsed mode, the laser releases high-energy pulses in an extremely short time, causing localized, instantaneous melting of the material, making it ideal for precision machining.

Main configuration.

water chiller

Featuring an integrated design, it offers two temperature control modes and various settings and fault display functions. The dual independent temperature control modes can meet the different cooling requirements of the laser and welding head, simultaneously cooling both the laser and optical components. It also boasts multiple alarm protection functions, such as compressor delay protection, overcurrent protection, water flow alarm, and over/under temperature alarms.
