Explore our core selection of fiber laser welders, mold remediation systems, and pulsed surface treatment units configured with industrial-grade beam delivery optics and continuous-wave stability.
A rigorous metallurgical overview of high-brightness fiber lasers, keyhole plasma dynamics, and precision thermal control systems engineered since 2010 by Shenzhen Youmir Laser Technology Co., Ltd.
Single-mode and optimized multi-mode fiber sources produce pristine Gaussian power distributions. The ultra-narrow focal spot delivers power densities exceeding 10⁶ W/cm², initiating immediate keyhole vapor capillaries in refractory and conductive alloys.
Our dual-galvanometer wobble heads oscillate the focused laser beam across adjustable geometric vectors up to 300 Hz. This eliminates the necessity of strict seam fit-up tolerances and enables crack-free bridging on irregular joints.
Thermodynamic stability is vital for coherent fiber delivery. Every machine integrates a closed-circuit refrigeration system with dual proportional valves, maintaining the optical resonator at 25°C ±0.5°C and the QBH output head at 30°C.
Unlike third-party equipment brokers who source off-the-shelf components without cohesive firmware matching, Youmir Laser executes 100% in-house engineering across optical collation paths, DSP control boards, kinematics firmware, and water-circuit manifolds in Shenzhen. This vertical integration guarantees long-term component interchangeability, exact parameter repeatability, and firmware-level diagnostics for foreign OEM brands.
Harnessing the world's most concentrated photonics industrial cluster in Shenzhen and Guangdong, Youmir delivers Tier-1 component integration, 35–45% procurement cost advantages, and rapid custom turnaround times.
Our headquarters in Guangming District, Shenzhen, situates our engineers within a 20-mile radius of raw quartz glass fabricators, precision CNC gantry mills, galvanometer motor manufacturers, and semiconductor packaging plants. This ultra-dense supply cluster collapses prototype-to-production cycles from months to days.
By eliminating overseas middleman markup, third-party distribution fees, and unnecessary licensing surcharges, our quotes deliver genuine factory-direct ROI. Overseas procurement teams acquire industrial-grade 1500W to 3000W fiber systems at 40% lower capital outlay compared to Western-assembled brands with identical core components.
Every laser welding, cleaning, and cutting machine undergoes a mandatory 72-hour continuous laser emission burn-in test at 100% duty cycle, high-temperature environmental chamber stress tests, beam profile coaxiality alignment, and helium-leak pressure checks before crating in export-grade treated timber cases.
The industrial joining paradigm is shifting rapidly toward multi-wavelength hybrid lasers, real-time closed-loop optical intelligence, and ultra-high-frequency scanning heads. Here is how Youmir engineering stays ahead of the technical curve.
Reflective metals such as pure copper (C10100/C11000) and gold absorb less than 5% of traditional 1070nm infrared radiation at room temperature, causing extreme back-reflection hazards and erratic spatter. Our R&D engineering incorporates 450nm blue semiconductor laser diodes coaxially combined with high-brightness fiber lasers. The blue wavelength boasts an absorption rate exceeding 40% in solid copper, heating the substrate to liquid phase instantly, while the infrared beam sustains deep-penetration keyhole geometry without spatter.
Conventional laser welding relies on post-process non-destructive testing (NDT), which inflates scrap rates during high-speed batch manufacturing. Youmir's automation roadmap integrates coaxial CMOS pyrometry and photodiode spectrometers directly into the optical head. Using deep-learning convolutional neural networks (CNNs), the machine monitors thermal radiation intensity, plasma plume luminance, and optical reflectivity at 10,000 samples per second.
Engineered to resolve thermal deformation, brittle intermetallic phase formations, and oxidation across demanding sectors from aerospace components to medical instruments.
Laser welding of prismatic cell battery terminals, aluminum side plates (3003/6061 series), and copper tab matrices. High-frequency beam oscillations suppress intermetallic compound (IMC) thickness below 10μm, ensuring low electrical contact resistance and superior mechanical shear strength.
Our boom and cantilever mold welders allow micro-wire deposition directly onto worn edges of H13, P20, and NAK80 injection tool steels. The focused pulse delivers metallurgical fusion without preheating, completely preventing edge sink, micro-cracking, or base-metal tempering.
Hermetic seam joining of thin-gauge Grade 5 Titanium (Ti-6Al-4V) and Inconel 718 nickel superalloys. Equipped with specialized trailing gas nozzles, our fiber welders maintain oxygen and nitrogen contamination levels below critical thresholds, preventing embrittlement.
Specialized 60W to 200W desktop YAG and QCW laser welders designed for platinum, 18K/24K gold, and 925 sterling silver repair. Stereomicroscope crosshair optics and sub-0.1mm micro-spots allow prong re-tipping directly adjacent to sensitive gemstones without heat shock.
Continuous seam welding of 304 and 316L stainless piping, hygienic tanks, and dairy enclosures. The smooth, oxide-free weld bead meets ASTM A380 criteria, eliminating the expensive post-weld pickling, chemical passivating, or abrasive grinding required by TIG welding.
Zero-spatter hermetic sealing of titanium pacemaker enclosures, endoscopic surgical scissors, and biocompatible implantable electronics. Closed-loop pulse shaping prevents thermal shock to internal silicon sensors and micro-circuit boards.

In-depth technical answers addressing power sizing, metal reflectivity, wire feeding kinematics, and global logistics directly from our chief optical engineers.
Laser power determines both depth of penetration and welding speed. For stainless steel, carbon steel, and galvanized metal: 1000W executes high-speed butt welds up to 3.0mm; 1500W is our most popular all-round model for general fabrication up to 4.5mm single-pass; 2000W extends penetration to 6.0mm with full root fusion; while 3000W penetrates up to 8.0mm in steel and up to 5.0mm in demanding, heat-dissipating aluminum alloys (5000/6000 series). Send your drawings and thickness specs to our Shenzhen application laboratory for free empirical weld cross-section testing.
Traditional fixed-spot fiber lasers require joint gaps under 0.1mm to avoid burn-through. Youmir systems utilize active dual-galvanometer wobble heads that oscillate the focused beam in adjustable patterns (line, circle, figure-8) from 0.2mm to 5.0mm wide. Combined with our microprocessor-controlled automatic wire feeder, the system easily bridges fit-up gaps up to 1.5mm to 2.5mm without sacrificing seam strength or visual aesthetics.
Shielding gas selection is determined by chemical affinity and surface requirements. Argon (>99.99% purity) is recommended for titanium, aluminum alloys, and high-spec carbon steel because its heavy atomic mass blankets the molten pool completely and prevents oxidation. Nitrogen is ideal for 300-series austenitic stainless steel; it acts as an austenite stabilizer, preserves corrosion resistance, and produces a bright, silver weld bead. Never use CO2 in fiber laser welding, as the intense beam will ionize the gas into carbon deposits and unstable plasma.
Our solid-state fiber laser sources have an MTBF (Mean Time Between Failures) rating exceeding 100,000 operational hours with zero scheduled maintenance. The only recurring wear items are the inexpensive protective quartz cover lenses (which protect the collimator and focus optics from spatter and cost roughly $3–$5 each) and the copper gas nozzles. A typical busy fabrication shop consumes 2 to 4 protective lenses and 1 to 2 nozzles per machine per month.
Yes. Beyond handheld machines, Youmir's automation engineering division manufactures 3-axis to 6-axis Cartesian CNC tables, boom-style mold repair gantries, and turnkey 6-axis robotic arm welding cells (interfaced with Fanuc, KUKA, ABB, or Yaskawa). We develop the complete kinematic PLC architecture, safety light curtains, pneumatic clamping fixtures, and automated wire feeding systems for batch industrial lines.
Standard lead time for handheld models is 3 to 7 working days; custom automated or boom systems require 12 to 20 days.
