Hebei Juliang Technology Co., Ltd. is one of the leading manufacturers and suppliers of 1500w‑3000w factory direct water in China. Please feel free to buy CE approved machinery made in China here from our factory. All customized machines are with high quality and competitive price.

The handheld water-cooled laser welding machine is specially designed for metal processing scenarios. It relies on a circulating water cooling system for heat dissipation, enabling long-term uninterrupted welding. This effectively addresses the issues of high temperature overheating and power attenuation of the equipment, making it suitable for high-intensity batch production in factories. The entire machine is equipped with a lightweight handheld welding gun, allowing for flexible movement. It can handle large pieces, corners, and irregular workpieces with ease. The entry-level threshold is low, and ordinary personnel can operate it with simple training without relying on experienced welders.
The equipment is compatible with various materials such as stainless steel, carbon steel, aluminum alloy, and galvanized sheet. Both sheet materials and pipe materials can be welded. The welding heat input is small, resulting in less workpiece deformation. The weld seam is clean and firm, significantly reducing subsequent processing such as grinding and polishing. The equipment is easy to maintain in the long term, with low-cost wear parts and controllable overall operating costs. It is widely used in sheet metal manufacturing, hardware products, door and window guardrails, and kitchen and bathroom pipe fittings processing. It has stable and reliable performance and is a practical equipment for upgrading welding processes in small and medium-sized factories.

500W-3000W Factory Direct Water-Cooled Handheld Laser Welder
Why does your shop still rely on grinding wheels after every weld?
If you spend more time sanding down beads and straightening bent metal than you do actual welding, you're not alone. A lot of workshops struggle with this. This handheld laser welder is a water-cooled fiber laser system running from 1500W up to 3000W. Instead of heating up a massive area around the joint, it delivers a tightly focused beam that melts metal in a split second. This means your thin stainless or aluminum sheets stay flat, and the weld looks clean enough that you can skip the grinding station entirely. We built this Compact Air-Cooled Laser Welding Machine specifically for shops that need to move quickly between different jobs without re-tuning a complex machine every time.

How we handle stainless and aluminum without the burn-through

Material selection is about matching the heat to the metal's behavior. Take stainless steel-it's notorious for warping and discoloration when you use traditional TIG or MIG. With our 1500W-3000W power options, you can dial in a pulse that lays down a bead with a perfect silver finish. It looks like it came out of a high-end fabrication shop, not a repair bay.

Aluminum is a different beast. It reflects nearly all visible light, which can damage the optics if the focus isn't right. We solved this by fitting a WSX LCN03A welding head with adjustable focus. It allows the operator to shrink the focal point until it penetrates the aluminum surface instead of bouncing off. It's the difference between a porous, weak joint and a solid, full-penetration weld.

A Real-World Payoff: Solving the "Heat Warp" Issue

We recently worked with a manufacturer that builds metal enclosures for industrial electronics. They were using MIG welding on 1.5mm galvanized steel boxes. The heat was so intense that the panels would bow, ruining the tight tolerances needed for their hinges. They scraped about 15% of their production.

We brought our 1500W model into their workshop for a trial. By reducing the heat input to a fraction of what MIG requires, the panels stayed perfectly flat. We didn't even need clamping jigs for most joints. On top of that, the galvanized coating near the weld didn't burn off, so they stopped worrying about rust spots. Their scrap rate dropped to under 3%. This wasn't a lab demo; it was a direct fix for a production bottleneck.

Installation, Maintenance & Production Flow

Setting this up is straightforward. You connect the water chiller, plug in the gas supply, and calibrate the laser head. It takes about 2 hours for the initial setup, and we provide free remote video support from our engineers during that time.

Important maintenance note: The protective lens and gas nozzle are wear items. You'll replace them every couple of weeks depending on how much you weld. Running with a scratched lens is the fastest way to ruin weld quality. Keep spares in your tool cabinet. If a system fault occurs, our team is available 24/7 to guide you through diagnostics and parts replacement.

How the machine is built (Juliang's production line):

Raw Material: High-tensile steel for the chassis.

Frame Welding: Precision jig construction.

Stress Relief: Heat treatment to prevent warping.

Machining: Using our own gantry mills for flatness.

Assembly: Integrating the laser source and cooling system.

Burn-in Testing: We run every unit at full power for hours before shipping.

Packing: Seaworthy wooden crates for international delivery.

. How does water-cooling actually improve the weld quality?
It keeps the laser source at a stable temperature. If the laser overheats, the beam focus drifts, resulting in inconsistent penetration along a long seam. The water cooling removes the heat constantly, so the power output remains exactly the same from the start of the weld to the end, guaranteeing a uniform bead profile.

2. What gas do I need for this machine?
You'll need a shielding gas cylinder. For most stainless and carbon steel applications, pure Argon or an Argon mix is standard. For aluminum, you often need a higher flow rate. The gas protects the molten pool from oxidation, which is what causes that black, crusty look on poor welds.

3. Can this weld dissimilar metals, like stainless to mild steel?
Yes, it can, but you have to adjust the settings and use a specific filler rod (like a nickel-based wire). However, we have to be honest: it's not always a perfect match. You need to test the joint carefully, as the different melting points can create brittle spots if the mix isn't right.

4. How long does it take to train a worker to use it?
If the operator is already experienced with TIG welding, they usually pick it up within 2 to 3 days of practice. The hardest part is getting the travel speed right. We provide video training during installation to speed this up.

5. What if the machine breaks during shipping?
We do very thorough burn-in testing before packing, so failure is rare. If something does happen, we diagnose it via video first. If a component is defective, we ship a replacement part quickly. For major issues, we offer a return-to-factory repair service covered under our warranty.
