The DPH-SS Series Jewelry Laser Welding Machine is a cutting-edge precision tool engineered for the jewelry manufacturing and repair industry. Adopting advanced Nd:YAG pulsed laser technology (1064nm wavelength) with maximum power options of 150W and 200W, this machine integrates imported ceramic focusing cavities, dedicated cooling systems, and high-precision microscope & CCD positioning systems. It is specifically designed for micro-welding tasks, enabling seamless welding, hole-filling, and spot-welding of precious metals and alloys. With adjustable parameters (pulse width, frequency, spot size), the DPH-SS series ensures minimal deformation, high weld strength, and eco-friendly operation—making it an indispensable asset for jewelry artisans and manufacturers.
Equipped with 150W/200W water-cooled/air-cooled Nd:YAG lasers, the machine delivers efficient spot soldering for gold, platinum, and silver jewelry. The minimal heat-affected zone (HAZ) eliminates deformation, preserving the original shape and luster of delicate pieces.
The integrated micro-positioning system (microscope + CCD camera) allows for accurate targeting of pinholes, loose claws, and sand holes. Weld strength is close to the base material, ensuring durable and invisible repairs.
Available in desktop and industrial models, the machine caters to diverse production needs. Imported core components guarantee a long lifespan, while factory warranty coverage provides peace of mind for long-term use.
Without the need for harmful chemicals or excessive energy consumption, the machine operates sustainably. Its high efficiency reduces production time, lowering overall manufacturing costs.
