Explore our core compact laser welding series, engineered for high-integrity joint metallurgy, thermal zone limitation, and agile industrial workshop integration.
Analyzing key industrial market trends, metallurgical transition from traditional arc processes, and the engineering thermodynamics governing micro-laser fusion.
Traditional arc welding methods such as TIG and MIG introduce massive heat input into thin-gauge alloys, leading to severe angular distortion, oxidation, and micro-cracking. Custom laser mini welding machines concentrate coherent light into a focused spot size of 0.2 mm to 0.6 mm, yielding an energy density exceeding 106 W/cm2. The resultant keyhole weld geometry confines the Heat-Affected Zone (HAZ) to microscopic margins, preserving temper and eliminating post-weld straightening.
Global fabrication is transitioning from monolithic, centralized welding cells to agile, cellular manufacturing stations. As industrial footprints become constrained and real estate costs escalate, tier-1 and tier-2 manufacturers demand mini desktop and compact vertical laser welders. These lightweight, mobile units allow surgical deployment directly onto assembly lines, medical cleanrooms, and maintenance suites without massive auxiliary infrastructure.
Modern engineering involves joined combinations of dissimilar and high-reflectivity alloys—including pure copper, brass, aircraft-grade 6061 aluminum, Kovar, and medical-grade titanium (Ti-6Al-4V ELI). Shenzhen Youmir Laser utilizes proprietary dual-wave and high-peak quasi-continuous wave (QCW) lasers to breach the high initial reflectivity threshold of non-ferrous metals without thermal runaways or surface spatter.
Shenzhen Youmir Laser Technology Co., Ltd. does not rely on third-party design houses. We develop the core optical paths, digital control software, and structural mechanics directly in-house.
Customization of continuous wave (CW), pulsed Nd:YAG, and Quasi-Continuous Wave (QCW) fiber laser engines ranging from 60W precision outputs to 3000W high-penetration powerheads. Fiber core diameters matched from 14 μm to 50 μm.
Proprietary galvanometer control boards support multiple oscillation geometries: linear, circular, figure-eight, and triangle wobble patterns up to 5 mm seam width, compensating dynamically for imperfect part clearances.
From compact desktop chassis with built-in stereo microscopes (10X-20X Leica/Olympus optical integration) to articulated cantilever booms for massive injection mold maintenance, chassis footprints are modified to client specifications.
Equipped with standardized industrial fieldbus protocols (Modbus-TCP, Profinet, EtherCAT). Handshake modules allow instantaneous communication with robotic arms (KUKA, ABB, Fanuc) and automated rotary indexing tables.

Use Case: Micro-seam joining of 18K yellow/rose gold, platinum 950, and 925 sterling silver. Fine repair of prong settings holding heat-sensitive diamonds, sapphires, and emeralds without thermal damage.
Empirical Result: Spot-weld diameter controlled at 0.15 mm under argon inert atmosphere. Porosity reduction of 98.4% compared with micro-torch flame soldering, zero gemstone discolouration.
Use Case: Hermetic laser micro-sealing of endoscopic surgical probes, orthopedic titanium pins, and cardiovascular sensor housings utilizing 316LVM stainless steel and Grade 23 Ti-6Al-4V ELI.
Empirical Result: Helium mass spectrometer leak detection rate < 1×10-9 mbar·l/s. Meets strict ISO 13485 bio-compatibility standards with zero flux residues and mirror-smooth surfaces.
Use Case: In-situ restoration of worn parting lines, sharp internal corners, and gating areas on plastic injection molds (NAK80, H13, P20 steel) without dismounting 2-ton core blocks.
Empirical Result: Deposition hardness matches parent alloy (50–54 HRC) utilizing 0.3–0.6 mm filler wire. Thermal sink completely negates annealing or micro-crack development around cooling channels.
