Laser micro welding puts a small, controlled heat input into thin walls, fine seams and heat-sensitive assemblies, producing low-distortion joints without filler.
Reach for laser when the joint is small, the metal is thin and heat has to stay tight.
Sealed tubes, housings and battery caps prone to burn-through. Heat sits along the joint line, not the surrounding wall.
Welds near electronics, plastics, set stones or heat-treated finishes. The narrow HAZ leaves adjacent features intact.
Autogenous edge-to-edge welds without wire or solder. Cleanup is short and polishing time drops.
Tight spot geometry and consistent penetration across a batch. Fits thermocouple tips, sensor pins and precision springs.
Laser is the wrong process when you need filler to bridge a gap or build up material. That work belongs to pulse arc / micro TIG. It's also not the pick for high-volume stacks of dissimilar-thickness sheet, where resistance spot is faster and more forgiving. If you only need to mark a serial or logo on the surface, laser marking is a different machine altogether.
See how this compares against the other processes for your material and volume.
Pick by part size, throughput and operator involvement.
| Benchtop | Fiber (fixed-station) | Handheld fiber | |
|---|---|---|---|
| Form factor | Enclosed cabinet + microscope | Fixed station cell | Portable head, umbilical |
| Operator | Manual, joystick-guided | Programmed or robot-fed | Trigger, hand-guided |
| Part size range | Very small to palm | Small to mid assemblies | Small to large frames |
| Throughput | Low to mid volume | Mid to high volume | Field, low to mid |
| Best-fit application | Repair, prototype, high-mix | Production seams and spots | Repair, retrofit, awkward parts |
| Automation | Manual only | Fixture & robot ready | Manual, limited automation |
| Footprint | Compact bench | Full cell | Movable, minimal fixed |
The spec lines that decide whether a machine fits your part.
That's a lot of variables. Send us your part and we'll come back with a recommended spec and a test weld.
Send my part for evaluation →Four steps we walk through with new buyers:
Material, thickness, weld type and existing tolerance. A photo plus a sentence beats a spec sheet.
We test-weld it, log parameters and photograph the cross-section.
Which family (benchtop, fiber, or handheld), which specs, which fixtures.
Run a small batch through our machine before you commit to the full order.
Post-shipment, an engineer stays on the account until your part parameters are locked in, whether that's a week of tuning or longer for tricky geometries.
Custom holders, indexed jigs and stage attachments matched to your part.
Lenses, nozzles, protective glass and electrodes available through our supply chain, so restock doesn't stall your line.
Remote onboarding for operators, with parameter walkthroughs and recorded sessions to replay.
Standard machine warranty, spec dependent. Extended plans available.
Test welds available before you place the order.
No obligation. Physical part or photograph.
Standard benchtop and fiber ship in a matter of weeks; custom cells longer. Exact bracket given with quote.
Deposit up front, balance before shipment. Trade references available for repeat accounts.
Implants, catheters and hermetic packaging.
See medical device welds →Framework repair and post soldering.
See dental lab welds →Wire buildup and detail restoration.
See mold and die welds →Hinge welds on titanium and stainless frames.
See eyewear welds →Send us the part. We test-weld, log parameters and return them before you commit to a machine.
Laser, pulse arc / micro TIG, resistance spot and laser marking, through one account.
For dealers who need their brand on the equipment, we scope private-label lots.
Operator manuals, parameter sheets and video walkthroughs with every machine.
If evaluation shows your part is better served by a different process, even one we don't sell, we tell you. We'd rather lose the order than sell the wrong machine.
You don't get handed off after shipment. We stay with your operator until the parameters for your part are set. Otherwise we haven't done the job.
Optical elements, protective glass, electrodes and consumables are available through our supply chain, so downtime after year one doesn't drag on.
Typical envelope for pulsed benchtop is 0.05–1.5 mm; fiber CW extends thicker. Actual limit depends on material and joint geometry, so we recommend a sample test before committing to a spec.
Yes for many combinations. Stainless-to-nickel and stainless-to-titanium are common; reflectivity and melting-point differences shape what works. Send the specific pair and thicknesses and we'll test-weld and report back.
Argon is baseline for most stainless work; titanium needs full puddle coverage plus cool-down protection to avoid oxide color; copper often benefits from helium blends. The shielding gas guide walks the setup metal by metal.
Depends on cosmetic and functional requirements. Low-HAZ laser welds are usually clean enough that light passivation or brush polishing is all that's needed; visible seams on cosmetic parts may still need media finishing.
Laser fits when you don't need filler and want minimum distortion; pulse arc fits when you need to add material or bridge a gap. For an assisted comparison across all four processes, see How to Choose.
We test-weld your actual part and return parameters, a cross-section photo and a process recommendation before you commit to a machine.
