Handheld Fiber Laser Welding Machine

This is a handheld fiber laser welding machine that ditches the water chiller. Instead of circulating coolant through a bulky tank, it uses forced-air heat dissipation to keep the laser source at operating temperature. The whole thing rolls around on casters and plugs into a standard wall outlet. We built it for fabricators who don't want to wrestle with a hundred-kilo stationary unit every time the job moves three meters to the left.

The handheld head itself is light-around 650 grams-so you're not nursing a sore forearm after a morning of seam welding. The fiber cable gives you ten meters of reach, which means you can tuck the main cabinet against a wall and still work on large assemblies without dragging the whole machine around.

Why Air Cooling Makes Sense for Most Shops

We get asked this a lot. Water-cooled systems have been the default for years, and they're not going away. But here's what pushed us toward air cooling: we kept hearing from customers who were tired of winterizing their equipment. One guy in a northern state called us after a chiller line froze and cracked-cost him three days of downtime and a expensive repair bill. That's the kind of problem air cooling sidesteps entirely.

The trade-off is the duty cycle. Air-cooled units can't sustain maximum power for hours on end the way heavy water-cooled industrial systems can. That's a real limitation, and we're upfront about it. If you're running a full production line that welds non-stop across three shifts, you probably want a chiller. But for job shops, maintenance departments, and fabricators who weld in bursts-say, fifteen minutes of welding, then fixturing and measuring-the air-cooled setup handles the workload just fine.

We've also noticed the air-cooled machine holds up better in hot environments. When the shop temperature hits 40°C, a water-cooled unit's radiator struggles to dump heat efficiently. The air-cooled design, with its larger fin array and direct airflow, actually handles high ambient temperatures more consistently

Quality Control – How We Test Before Shipping

Each unit goes through a standard sequence before it leaves our facility. We don't spot-check; we test every machine.

Optical alignment – The beam path is calibrated using a high-precision collimator to confirm energy delivery is consistent across the full operating range. This is the step that separates a reliable laser from a frustrating one.

Power calibration – We verify actual output at the nozzle matches the set power across the adjustment range. Laser power meters provide the measurement, not guesswork.

Burn-in run – The machine operates at rated power for two hours to verify thermal stability and cooling performance. The temperature sensors log data throughout.

Weld sample test – We weld a standard coupon of 304 stainless, check penetration depth, bead consistency, and inspect for porosity or undercut.

Wire feeder test – Feed consistency is verified at different feed rates to ensure smooth delivery.

Safety system check – Emergency stop, safety interlock, and temperature warnings are confirmed functional.

The unit gets packed with high-density foam in an ISPM-15 certified crate. International shipments are inspected and strapped accordingly.

About Hebei Juliang Technology

We started in CNC cutting back in 2014-portable plasma cutters, gantry systems, pipe cutters. Laser welding came later, around 2020, after we invested in R&D and filed several patents [citation:document]. The company has grown through three facility expansions, the latest in 2025, to accommodate production capacity for laser welding and cutting equipment.

We're registered as a high-tech enterprise in Hebei Province, classified as a specialized and innovative small-to-medium enterprise, and we hold CE certification for our export models [citation:document]. Our sales network covers domestic manufacturing and international markets-Southeast Asia, Russia, Africa, Europe, and the Americas.

That history matters because it means we've been through the learning curve. Early laser products had issues we've since addressed through design revisions and supplier changes. The current generation reflects that accumulated experience.

Frequently Asked Questions

What's the real difference between air-cooled and water-cooled laser welders?

Air-cooled units use fans and heat sinks to dissipate heat-they're lighter, simpler, and don't freeze in winter. Water-cooled systems have a chiller and coolant loop, which adds weight and maintenance but supports longer continuous operation. Choose air-cooled for portability and convenience; choose water-cooled for 24/7 production.

How long does the laser source last before needing replacement?

The fiber laser module is rated for 80,000 to 100,000 hours. That's under standard operating conditions with regular lens cleaning and proper power management. Most users will never reach that limit-it's effectively the life of the machine.

Can I weld reflective metals like aluminum or copper without extra equipment?

Aluminum can be done with the standard head but works much better with the wobble oscillation option. Copper is more challenging-absorption is lower, so you need slower speeds and might want a 1500W or higher power unit.

What's included in the 1-year warranty?

The machine (excluding consumables like nozzles, lenses, and feed tubes) is covered for one year. The laser source is covered for two years. Warranty covers manufacturing defects, not damage from misuse or wear items.
