Smelting And Casting Equipment Manufacturing Expert
Tospmelt mini laser welding machine is a compact, high-precision device designed for welding noble metals in the jewelry industry.
Using a focused and amplified light beam, it produces solid, invisible welds within seconds. The laser beam’s intensity and focus can be precisely controlled by the operator.
When repairing or adding metal, the machine welds the same noble alloy with localized heat, ensuring seamless joints without discoloration.
Tospmelt jewelry laser welder is capable of welding base metals, karat gold, sterling silver, palladium, platinum, and more.
Its compact design allows continuous welding while holding delicate precious metal pieces by hand. Compared to traditional soldering, laser welding is faster, cleaner, and more cost-effective for both manufacturing and repair applications.
Tospmelt jewelry laser welding machine delivers high welding precision and control, allowing users to weld even the smallest and most delicate parts without damage.
Capable of handling complex joints and hard-to-reach areas, the mini laser welder enables welding of dissimilar metals that are difficult for traditional methods.
With a low heat input (≤5KW), the machine minimizes component distortion, making it ideal for precious metal repair and fabrication.
Tospmelt mini laser welder supports continuous and repeated welding, offering faster and cleaner results than conventional techniques.
It produces high-strength welds without the need for filler material, ensuring excellent weld quality — even suitable for medical-grade applications.
Equipped with dual cooling systems (water + air cooling), it enhances welding efficiency and extends machine lifespan.
Its compact, portable design makes it a popular choice across jewelry, medical, electronics, and automotive industries.
The welder features an imported ceramic condenser cavity, offering high resistance to corrosion and heat, with a service life of up to 8–10 years.
Integrated microscope and camera systems allow precise targeting and positioning of metal parts, ensuring accurate results every time.

How To Test The Purity Of Your Gold?
Yes, laser welding can achieve joint strengths comparable to, or even exceeding, MIG and arc welding in many applications.
·Precision and control: Laser welding offers a highly focused heat source, resulting in deep, narrow welds with minimal distortion.
·Smaller heat-affected zone (HAZ): Compared to MIG and arc welding, laser welding causes less thermal impact, preserving the base metal’s strength.
·Material adaptability: While MIG and arc welding are widely used for structural applications, laser welding excels in fine, high-precision welding where clean seams and minimal rework are important.
The choice between welding methods ultimately depends on application, material type, and production scale.
Yes, laser welding often uses shielding gas such as argon or nitrogen to protect the molten pool from oxidation and contamination. Although laser welding is a non-contact process, shielding gas helps achieve better weld quality, especially when working with reactive metals like aluminum or titanium. In some high-vacuum laser welding setups, shielding gas may not be required. Proper gas use improves weld clarity, consistency, and durability.
The weldable thickness depends on the laser power, material type, and beam quality. Generally:
·Low-power lasers (e.g., 100–200W) weld up to 0.5–1.5mm thickness.
·High-power lasers (e.g., >1000W) can weld up to 6mm or more in metals like stainless steel or mild steel.
Thicker sections may require multiple passes or are better suited to arc welding techniques. Always refer to machine specifications or test samples for precise results.
Laser welding is safe when proper precautions are followed.
·Laser radiation: Always wear certified laser safety goggles rated for your machine’s wavelength.
·Fume extraction: Use proper ventilation or fume extractors, especially when welding coated or alloyed metals.
·Protective barriers: Use enclosures or shields to prevent accidental laser exposure.
·Electrical and fire safety: Maintain safe handling of high-voltage systems and keep flammable items away.
·Operators must be trained and follow standard operating procedures. PPE, signage, and emergency shutdown features are essential.
