A Semsons Tech laser welding machine for jewellery repair and manufacturing. Short laser pulses melt the metal only at the joint you line up under the microscope.
✔ 200 W pulsed YAG, 1064 nm - up to 150 J in one pulse
✔ Weld spot 0.2 to 3.0 mm - prong tips to thicker joints
✔ 10x microscope with CCD - see the joint before you fire
✔ Heat stays at the joint - many repairs with the stones in place
✔ Chiller inside the cabinet - no separate unit beside it
✔ Single-phase 220 V - floor cabinet on castors

Joins gold, silver and platinum at the joint, without heating the whole piece.
A torch heats everything around a joint. On a set piece that often means taking the stones out, soldering, then setting them again. This machine welds with short pulses of laser light, aimed at a spot as small as 0.2 mm that you line up under a 10x microscope. The metal melts only at that spot and sets again within moments. Many workshops call it a laser soldering machine. It welds: the metal of the piece fuses to itself, with no solder in the joint.
The laser inside the cabinet gives out a pulse of infrared light at 1064 nm. The optics focus that pulse onto the joint you have lined up under the microscope. Each pulse lasts 0.1 to 20 milliseconds and carries up to 150 joules, which melts a small pool of metal at that spot. The pool closes the joint and sets again. Argon gas flows over the spot while the metal is molten, so the weld comes out bright instead of black.
| The job | What the laser does |
|---|---|
| Ring sizing | Closes the shank after sizing, often with the stones left in the head |
| Worn or broken prongs | Builds the prong tip back up in place |
| Chain and clasp repair | Joins a link or jump ring without heating the rest of the chain |
| Porosity in castings | Fills the pinhole with metal, ready to be finished flush |
| Worn or thin sections | Adds metal with filler wire where a piece has worn thin |
| Tacking parts together | Holds two parts in position before soldering or finishing |
After welding and polishing, an ultrasonic cleaner lifts polishing compound out of the setting.
| Question | Laser welding on this machine |
|---|---|
| How much of the piece gets hot? | Only a small area around the weld spot |
| Is there solder in the joint? | No. The metal of the piece fuses to itself |
| Do the stones have to come out? | Often not. Heat-sensitive stones still need distance or removal |
| How precise is it? | Weld spot from 0.2 mm, placed under a 10x microscope |
| Does the joint show after polishing? | The joint is the same metal, so there is no solder line of a different colour |
Keep the beam on the metal, never on a stone. Emerald, opal, pearl and treated stones are more sensitive to heat: weld further away from them at lower energy, or take them out first.
If you do not know the alloy of a piece that came in over the counter, check it on a gold testing machine first, then set the pulse for that metal.

Repair and manufacturing work where a torch would heat too much of the piece: ring sizing, re-tipping prongs, chain and clasp repair, filling porosity in castings and tacking parts together.
In the jewellery trade both names are used for this machine. Strictly, it welds: the laser melts the metal of the piece itself, so there is no solder in the joint.
Often, yes. The heat stays close to the weld spot, so many repairs are done with the stones in place. Keep the beam off the stone, and take heat-sensitive stones such as emerald, opal and pearl out, or weld further away from them at lower energy.
Gold in yellow, white and rose, silver, platinum and palladium. Silver needs more energy per pulse than gold for the same joint.
Yes, for a clean weld. The argon nozzle is built into the machine. You arrange the argon cylinder and regulator locally. The gas keeps air off the molten metal, so the weld stays bright.
Not for a tight joint, where the two edges melt into each other. For a gap or a worn section, feed a filler wire of the same metal into the spot as you pulse.
A single-phase 220 V, 50 Hz power point, an argon cylinder and floor space for the cabinet and the operator's seat. The chiller is inside the cabinet, so there is no separate cooling unit. The cabinet is on castors.
Yes. Our technician installs the machine at your workshop and trains your operator on site. See installation, training, spares and service.
It is an industrial laser. Nobody should run it before the on-site training, which covers eye protection and safe handling. Keep hands out of the beam path.
