Spot Welding Machine for Jewellery

In the world of fine jewellery, every weld affects both value and beauty. Whether crafting rings, necklaces, and earrings, or performing repairs, hole filling, and prong setting, a high-quality spot welding machine for jewellery is indispensable for jewelers and artisans.

A spot welding machine for jewellery is a precision device specifically designed for metal joining in the jewellery industry, capable of welding all common precious metals including gold, silver, platinum, palladium, titanium, and their alloys. Its core advantages-minimal heat-affected zone, precise and aesthetic welds, and the ability to work near gemstones without damage-have made it essential in jewellery manufacturing, repair, and precision micro-component welding.

Precise Parameter Control for Consistent Joint Strength
Stainless steel spot welding is sensitive to welding current and time. For SUS301L stainless steel, studies show optimal mechanical properties at 8.0kA welding current, 150ms welding time, and 0.35MPa electrode pressure. Our machines feature high-precision control systems for consistent nugget size and strength.

Nugget Size Determines Strength - Scientifically Validated
Research shows that the tensile shear load of stainless steel spot-welded joints is closely related to nugget size. For dissimilar ferritic-martensitic stainless steel welding at 8kA, peak nugget size of 5.6mm corresponds to maximum tensile shear load of 5.6kN. Joint failure follows the pull-out mode along the HAZ with plastic deformation, ensuring structural safety.

Indentation-Free Spot Welding - Eliminating Post-Processing
For unpainted stainless steel appearance parts, we offer indentation-free resistance spot welding using tiny stainless steel balls as intermediate filler between sheets. Research confirms surface indentation depth less than 1% of sheet thickness - virtually invisible to the naked eye, eliminating the need for grinding.

Broad Precious Metal Compatibility
Supports gold, silver, platinum, palladium, titanium, and their alloys, as well as stainless steel, copper, brass, and more. Select models handle white gold, platinum, and other challenging alloys.

Microscope Precision - Intuitive Operation
Equipped with 10x magnification microscope or CCD display, weld positions are clearly visible with positioning accuracy to 0.02mm. Automatic beam shielding protects the operator's eyes.

24/7 Continuous Operation - Stable and Reliable
Ceramic pumping chambers offer corrosion resistance, high temperature tolerance, and high photoelectric conversion efficiency-supporting 24-hour continuous operation.
