Engineered for extreme duty cycles, minimal heat affect zones (HAZ), and structural seam integrity. Explore our initial series of specialized QCW, mold repair, and continuous fiber workstations.
As precision metal fabrication shifts from conventional arc processes (MIG/TIG) toward high-power density photonic welding, modern industrial manufacturers require custom architectures tailored to metallurgical constraints, thermal expansion gradients, and automated cycle times.
Pioneering fiber laser development since 2010
Tier-1 production facilities across 50+ countries
Outperforming conventional TIG on light alloys
Ultra-concentrated energy, zero thermal warping
Industrial fiber lasers provide energy density exceeding 106 W/cm2, instantly vaporizing metal to establish a vapor capillary (keyhole). This allows high aspect ratio welds with deep penetration and narrow seam widths, cutting total energy input by 80% compared to traditional resistance or arc techniques.
Modern custom welding heads utilize dual-axis high-speed galvanometer mirrors to generate circular, sinusoidal, and figure-eight beam oscillation patterns. This dynamic stirring of the melt pool effectively bridges gaps up to 1.5mm, degasses hydrogen to prevent porosity, and widens the joint bond strength.
Youmir Laser’s proprietary pulse control shapes laser output ramps down to millisecond increments. This avoids brittle intermetallic compound (IMC) formation when joining highly divergent metals such as copper-to-aluminum in EV pouch cells or titanium-to-stainless steel in aerospace sensors.
From heavy automotive press lines to micro-precision medical devices, our custom laser welding equipment delivers targeted metallurgical advantages across rigorous global industrial environments.
Wobble-assisted fiber lasers weld battery module busbars, cylindrical cell tabs, and electric motor hairpin stators with sub-milliohm electrical resistance. Rapid cycle speeds eliminate copper spatter while maintaining high shear and tensile strength against vibration fatigue.
Our specialized boom and cantilever mold systems deposit matching H13, P20, and NAK80 tool steels directly into micro-cracks, chipped parting lines, and worn cavities without thermal annealing. The mold base retains original hardness without sinking or post-weld stress relieving.
QCW pulsed laser welders execute micro-seams on 316LVM medical stainless, nitinol stents, and titanium pacemaker housings. Seams remain hermetically sealed under helium leak testing (rate < 1×10-9 mbar·L/s) while preserving biological passivation surfaces.
Microscope-integrated benchtop and vertical systems allow artisans to re-tip prongs right beside heat-sensitive emeralds or diamonds without unsetting stones. High-frequency pulsing melts 18K/24K gold, 925 silver, and platinum without surface oxidation or porosity.
Handheld and automated CW machines join kitchen sinks, commercial HVAC ductwork, and architectural facade panels. With continuous inert gas coverage, seams achieve an Ra < 0.4μm finish, eliminating 90% of traditional secondary grinding and polishing labor.
Hermetic sealing of thin-walled Inconel 718 and Hastelloy engine thermocouples, exhaust ducting, and fuel lines. Deep penetration with minimal metallurgical dilution retains base metal creep resistance and high-temperature stress capability.
As industry 4.0 interconnectivity and zero-defect quality mandates redefine industrial manufacturing, Youmir Laser invests aggressively in closed-loop photonic architectures.
Integrating Optical Coherence Tomography (OCT) coaxially through the beam delivery head to scan the melt pool keyhole in real-time at 50 kHz. This yields micron-accurate depth data and adaptive seam tracking, automatically compensating for work piece gaps on high-speed robotic production lines.
Infrared (1064nm) lasers suffer high initial reflectivity when processing pure copper and gold (up to 95% reflected). Our dual-beam hybrid engine combines a 450nm high-absorption blue diode laser to melt the substrate with an IR fiber laser to achieve deep, spatter-free penetration.
Coaxial photodiodes capture plasma emission spectra and sound emission signatures during keyhole formation. Embedded machine learning inferencing models detect false welds, spatter explosions, and cracks instantly, stamping an individual digital birth certificate on every manufactured joint.
Every CNC workstation and multi-axis gantry is equipped with secure MQTT/OPC-UA interfaces for ERP synchronization. Real-time logging of optical degradation, chiller pressures, and shielding gas flow allows preventative maintenance before costly line stoppages occur.

Youmir Laser operates from Guangming District, Shenzhen—the global epicenter of precision optoelectronics. Our direct factory infrastructure delivers unmatched economic efficiency and engineering agility.
Rather than acting merely as an integrator, Youmir Laser designs its own proprietary optical paths, beam shaping collimators, wobble controller software, and heavy-duty gantry mechanics in-house. This gives international distributors absolute direct access to source engineers without middleman margins.
Surrounded by a dense, tier-1 supply ecosystem of precision CNC machine builders, semiconductor diode producers, and optical glass coating labs in Shenzhen and Dongguan, we assemble, stress-test, and ship custom configurations in a fraction of Western lead times.
Every machine undergoes non-stop 72-hour cyclic endurance stress testing under peak thermal loads before crating. Beam profile quality (M2 factor), optical transmission loss, and chillers are calibrated under ISO 9001 certified protocols for guaranteed out-of-the-box reliability.
Exporting to over 50 nations across Europe, North America, Southeast Asia, and Latin America, Youmir Laser machines are architected to meet rigorous international statutory safety regulations.
Our laser equipment complies with EU Machinery Directive 2006/42/EC, EN 60825-1 (Laser Safety), and US FDA CDRH 21 CFR 1040.10. Safety circuits incorporate dual-channel emergency stop interlocks, protective optical OD6+ observation windows, and automatic electrical beam dump shutters.
Our engineering command center in Shenzhen and regional partners in North America, Europe, Thailand, and Malaysia provide 24/7 multilingual technical triage. We provide cloud diagnostics, parameter guidance, and full on-site installation and operator safety training.
To eliminate costly shop floor downtime, Youmir maintains buffer stock of protective quartz windows, copper nozzles, collimating optics, and wire-feed liners with rapid air-courier dispatch worldwide, alongside guaranteed 10-year component availability.
