Product Overview
The jewelry laser spot welder is a high-precision laser welding system designed specifically for the intricate processing of gold and silver jewelry. Featuring a compact, space-efficient design, it is perfectly suited for the limited workspaces found in jewelry workshops and manufacturing facilities. The equipment excels in precision micro-welding and seamless repair, enabling efficient tasks such as fixing bubbles, filling holes, repairing gaps, and spot-welding setting prongs. The laser spot size is fully adjustable, ensuring a minimal heat-affected zone; the resulting welds are smooth, refined, and aesthetically pleasing, requiring no complex post-processing. With precise positioning, the system ensures no damage to surrounding gemstones, plated surfaces, or the base material, preserving the original quality and texture of the jewelry. It is the premier choice for jewelry refurbishment, repair, and custom fabrication.

Core Advantages
1. Proprietary High-Performance Laser Power Supply for Low-Heat Micro-Welding: Equipped with a self-developed, high-performance laser power supply, the system delivers stable, high-energy pulses. It achieves precise welding even at low power settings, resulting in a minimal heat-affected zone. The workpiece remains cool during the process, effectively preventing the deformation or discoloration of precious metals.
2. Automatic Light-Shielding System for Operator Safety: The unit comes standard with an automatic light-shielding system that activates the moment welding begins. This protects the operator’s eyes from intense light, ensuring a safe, compliant working environment suitable for long-term, routine production.
3. Filler-Free Welding: Efficient, Eco-Friendly, and High-Yield: No additional filler material is required. The process offers high welding speeds, strong bond points, and dense, reliable seams. Workpiece deformation is kept to an absolute minimum, with no contamination, oxidation, or blackening at the weld points. The superior finish significantly reduces the need for subsequent grinding or polishing, making the process both highly efficient and environmentally friendly. 4. Imported Laser Cavity – Stable, Durable, and Maintenance-Free: Equipped with a ceramic laser cavity imported from the UK, featuring excellent light transmission and high focusing precision, ensuring high-performance and highly stable operation. The system supports 24-hour continuous operation with exceptional stability and requires no maintenance for up to 10,000 hours, significantly reducing operational and maintenance costs.
5. Proprietary Crystal Cooling Technology – Lowering Operating Costs: Features a unique YAG crystal cooling system that optimizes laser beam quality, extends the service life of the xenon lamp, and reduces the frequency of replacing consumable parts—delivering superior cost-effectiveness over long-term use.
6. Highly Adjustable Parameters for Diverse Applications: Key parameters—such as energy, pulse width, frequency, and spot size—can be precisely adjusted across a wide range, enabling a variety of high-precision welding results. The control lever, housed within a sealed cavity, offers an intuitive and efficient adjustment experience, allowing even beginners to get started quickly.
