Explore our flagship configurations engineered for continuous duty, structural integrity, and micrometric joint control across stainless steel, aluminum, brass, and structural alloys.
Operating at a continuous wave (CW) wavelength of 1070 nm ± 10 nm, the 1500-watt fiber laser architecture achieves energy density profiles exceeding 1.2 × 10⁶ W/cm². This fundamentally transforms metal joining through keyhole mode welding, eliminating thermal deformation and micro-cracking.
Situated in the heart of the Guangdong-Hong Kong-Macao Greater Bay Area photonics cluster, our Shenzhen manufacturing facility leverages vertically integrated supply chains. By sourcing fiber cores, collimators, and specialized Peltier cooling components directly with zero regional freight latency, we achieve up to 38% cost efficiency without compromising on military-grade component selection.
Unlike fixed-spot fiber heads, the Youmir Light Weld 1500 system integrates dual-axis galvanometric oscillation (wobble). With customizable wobble widths from 0.5 mm to 5.0 mm at frequencies up to 300 Hz, operators bridge loose seam gaps up to 2.5 mm with automatic wire feeding, drastically relaxing mechanical tolerances on CNC-sheared and stamped parts.
Every laser source and integrated chiller undergoes a non-stop 72-hour thermal stress test and optical power stability audit prior to crating. Beam drift is strictly constrained to < 1.5% RMS under maximum load cycles, ensuring out-of-the-crate reliability for automotive tier-1 and aerospace contract fabrication plants across the globe.
Global procurement teams demand unvarnished cost transparency. Below is our baseline factory-gate price schedule (FOB Shenzhen / CIF Global Hubs), illustrating standard industrial configurations, distributor volume tiers, and custom turnkey automation additions.

TIG welding demands certified master welders commanding $35–$55/hr in North America and Western Europe. Because the Light Weld 1500 utilizes pre-programmed process parameter libraries, operators achieve certified code-quality butt and corner welds with less than 2 hours of baseline training, slashing specialized labor overhead by up to 65%.
High-efficiency fiber lasers convert wall-plug AC power into optical beam energy at over 35% electrical-to-optical efficiency (compared to 15–20% for conventional TIG/MIG power sources). Utilizing argon or nitrogen shielding at lower flow rates (12–15 L/min), production facilities report electrical energy savings averaging $1,400 per machine per shift-year.
Factoring in 400% faster joint completion speeds, near-complete eradication of post-weld abrasive flap-disc grinding, and zero rework scrap on thin-gauge enclosures, mid-sized fabricators calculate full capital amortization (Capex recovery) within 3.2 to 5.8 months of steady shop floor operation.
Understanding the interplay between laser irradiance, welding travel speed, and shielding gas kinetics is crucial for preventing porosity, undercut, and metallurgical degradation in critical load-bearing assemblies.

Because energy is applied in a micron-focused beam, heat input per unit length (Joules/mm) is up to 80% lower than MIG welding. Ultra-thin sheet metal components remain perfectly flat, eliminating secondary hammer straightening.
Food, medical, and semiconductor piping assemblies achieve fully penetrated, mirror-smooth internal roots without oxidation crevices, passing stringent helium mass-spectrometer leak tests with zero reject rates.
The system easily bridges dissimilar metallurgical couples—such as copper to aluminum in EV battery busbars, or stainless steel to carbon steel in architectural railings—preventing brittle intermetallic phases.
By switching the optical nozzle and triggering our high-frequency pulse cleaning mode, operators clean oxidation layers, rust, and spatter before and after welding using the exact same hand torch.
Across more than 50 export countries, Shenzhen Youmir Laser systems have proven their reliability in demanding localized operating environments, from high-humidity coastal shipyards to sub-zero Nordic sheet fabrication facilities.
Scenario: EV battery pack enclosures, high-current copper-aluminum busbar bridges, aluminum battery trays, and exhaust silencer assemblies.
Solution: The Light Weld 1500 delivers deep, spatter-free penetration without piercing thin cell jackets, achieving 100% electrical conductivity integrity and shock-resistant weld beads.
Scenario: Architectural balustrades, commercial elevator car panels, stainless kitchen sinks, and luxury retail fixtures.
Solution: Mirror-finish and brushed hairline stainless surfaces require zero grinding or abrasive blending post-weld. Weld beads remain silvery-white and ductile, preserving premium surface aesthetics.
Scenario: Plastic injection parting line chips, stamping die edge fractures, and casting pinhole repair.
Solution: Combined with our micro-wire feeder and specialized boom configurations, tool rooms restore hardened H13 and P20 tool steel surfaces with zero base-metal thermal sink or micro-annealing.
A precision electrical enclosure shop in Ohio transitioned from 6 TIG workstations to 2 Youmir Custom Light Weld 1500 units. Welding cycle times on 16-gauge NEMA 4X 304 stainless cabinets dropped from 22 minutes per cabinet to just 4.5 minutes. Secondary deburring and chemical pickling paste steps were completely eliminated, resulting in an audited annual labor and consumable savings of $142,000 across their first full fiscal operating cycle.
Procuring industrial laser machinery directly from China requires strict adherence to international safety directives and electrical codes. Here is how Youmir Laser guarantees plug-and-play compliance worldwide.
Integrated multi-level safety interlocks including dual-channel contact grounding loops (laser fires only when torch nozzle makes electrical contact with workpiece), emergency stop circuits, fiber break detection, and key-switch administrative lockouts compliant with EN 60825-1 and FDA CDRH 21 CFR standards.
Equipped with universal dual-frequency industrial power architectures: Single-phase 220V ± 10% (50/60Hz) or optional stepped three-phase 380V/480V for heavy European and US factory environments. Premium Schneider or Omron switchgear prevents voltage dips from tripping chiller compressors.
Every shipment is treated with vacuum-sealed anti-moisture barrier film, heavy desiccant packs, and crated inside fumigated ISPM-15 compliant sea-freight wooden cases with reinforced shock indicators. Torches and fiber conduits are immobilized on vibration-dampening cradles to prevent optical core fracture.

For stainless steel and mild carbon steel, a 1500W system achieves full-penetration keyhole butt welds up to 4.0 mm in a single pass with dual-sided shielding and proper edge fit-up. In structural aluminum (which exhibits higher optical reflectance and thermal conductivity), single-pass capability tops out at 2.5 mm – 3.0 mm. Thicker sections (up to 6.0 mm) can be joined via double-V bevels or multi-pass wire-fed techniques.
While air-cooled systems offer lighter cart weight and reduced footprint, water-cooled architectures remain the gold standard for continuous industrial manufacturing. Our dual-circuit refrigerated water chiller independently regulates laser cavity temperature and optical head optics, maintaining continuous 100% duty cycle operation even in ambient shop conditions exceeding 40°C (104°F) without thermal de-rating.
The primary consumables are protective focus cover glasses (lenses), brass wire-feeder guide nozzles, and wire feeder drive rollers. A typical protective lens lasts 150 to 300 welding hours depending on cleanliness, shielding gas purity, and spatter control. Youmir equips every machine with a 1-year bulk consumable starter pack to guarantee uninterrupted operation.
Yes. Our fiber laser sources are engineered with built-in 5-stage back-reflection isolators that absorb reflected photons without damaging laser diodes. Coupled with our wobble beam oscillation, the initial surface reflectivity barrier is breached instantly, enabling consistent fusion on brass (up to 2.0 mm) and pure copper (up to 1.5 mm).
Pure industrial argon (≥ 99.99%) is the universal choice for stainless steel, carbon steel, and aluminum. For stainless steel where root discoloration must be eliminated at high travel speeds, high-purity nitrogen (99.999%) can also be utilized. Typical torch consumption ranges between 12 and 18 liters per minute (L/min) under active trigger operation.
We provide a 2-year core warranty on the fiber laser source and 1-year comprehensive machine warranty. Overseas buyers receive 24/7 direct video technical diagnosis from Shenzhen engineering specialists. Replacement modules are dispatched via DHL/FedEx priority air freight within 24 hours of ticket logging, backed by our growing network of regional distributor service centers.
