The jewelry laser spot welding machine utilizes 1064nm wavelength YAG laser technology, offering a single pulse energy of up to 90J and an adjustable spot size from 0.1-3.0mm. It supports non-destructive welding of highly reflective metals such as gold, silver, and platinum, with a heat-affected zone (HAZ) of less than 0.2mm, ensuring no oxidation or deformation on the jewelry surface. Integrating a high-definition CCD microscope observation system and an electronic light filter device, operators can clearly view welding details without wearing protective goggles. Coupled with an ergonomic design, it can complete over 500 precise welding tasks per day, boosting efficiency by 5 times compared to traditional methods. It is an innovative tool for jewelry repair, setting, and micro-engraving.

Applications
Precious metals: Gold (24K/18K), silver, platinum, titanium alloy, K gold.
YAG laser & xenon lamp
Employs a 1064nm wavelength laser with single pulse energy up to 50-110J, providing concentrated photon energy and a heat-affected zone of only 0.2-0.5mm, ideal for cold processing highly reflective metals like gold, silver, and platinum, preventing oxidation and deformation. The xenon lamp's trigger voltage is precisely controlled, with discharge energy fluctuation <3%, ensuring welding consistency and an electro-optical conversion efficiency ≥30%.
Touch screen
Features a high-definition LED touch screen that supports Chinese-English switching and real-time display of welding parameters for intuitive operation. It includes a built-in crosshair microscope with magnification ≥20x, allowing clear positioning of 0.1mm-level welds and preventing misoperation.
Automatic shading system
Automatically activates the shading hood during welding, with light transmittance <0.1%, preventing laser scattering from harming the eyes and complying with Class 1 safety standards.
Emergency stop button
When the emergency stop button is triggered, the laser output is cut off within <0.1 seconds, ensuring operational safety.
Can this precision welding machine weld plated precious metals (e.g., gold/silver plated jewelry)?
Yes, it can weld gold and silver plating. The heat-affected zone is ≤0.2mm, ensuring no damage to the plating layer.
What is the water change frequency for the built-in water tank of this Metal Craft Welding Machine?
It is recommended to change the water every 3 months, using distilled water or purified water.
Can the jewelry welder work continuously for long periods, or does it require breaks?
It supports 8 hours of continuous operation, with automatic power reduction for high-temperature protection.
What after-sales service and warranty policies are provided after purchasing the metal welder?
The entire machine comes with a one-year warranty; consumables such as lenses are not covered by the warranty.
What should be noted when it comes to jewelry soldering?
Before jewelry welding, ensure the metal material is thoroughly cleaned. Then, select the appropriate welding tools and master the welding technique. During welding, heat the welding material to its melting point and apply it to the surfaces of the two metals. After welding, the welded area should be polished to be smooth and seamless, ensuring the aesthetic appeal of the jewelry.
Why do you need a laser welder to weld your jewelry?
A jewelry laser welding machine is ideal for all traditional metals used in jewelry. It can weld precious metals, including sterling silver, K gold, palladium, titanium, and even platinum. Laser welding offers flexibility for welding platinum, which was once a very difficult metal to work with in jewelry. Furthermore, laser welding can join non-metal components like glass and porcelain with metal. Most importantly, standard or portable laser welding machines are even capable of welding jewelry parts of various shapes.
Can you provide welding parameters for welding platinum, gold, and silver with the welding equipment?
For 18K Gold Craft Welding:
Laser Current (Power): 15%
Pulse Width: 1.8 ms
Spot Size: 0.3 mm For Pure Gold Craft Welding
Laser Current: 46%
Pulse Width: 5.2 ms
Spot Size: 0.5 mm
Note: It is recommended to blacken the surface of the weld spot before welding (e.g., using a laser absorber or black marker pen) to enhance laser absorption, preventing unstable welding or energy waste caused by laser reflection.
