Custom Automatic Laser Welder Manufacturer & Pricelist

Galvanometer welding systems steer the laser beam via ultra-light mirrors mounted on high-frequency voice coil actuators through an F-theta flat-field objective lens. They reach scan speeds up to 5,000–7,000 mm/s with zero inertial lag, making them ideal for high-density, multi-point, or small contour welds (such as EV battery tabs, cylindrical cells, micro-relays, and electronic terminals) within a localized 100x100 mm to 300x300 mm field. In contrast, Cartesian CNC Gantry systems move the entire heavy processing optical head along precision ball screws and linear guideways across massive working envelopes (e.g., 1000x1000 mm to 3000x1500 mm). They deliver high continuous rigidity for deep-penetration structural seams, pressure vessels, long sanitary pipes, and heavy sheet metal assemblies where sustained travel consistency is paramount.

Shielding gas selection directly impacts melt pool chemistry, ionization plasma suppression, and cosmetic oxidation. For austenitic stainless steel (304, 316L), high-purity Argon (99.999%) or Nitrogen is standard. Nitrogen provides high cosmetic silver-white finishes and slightly strengthens the weld via interstitial nitrogen absorption, though Argon must be selected if maintaining strict non-magnetic ferrite balance is required. For aluminum alloys (5000, 6000 series), ultra-pure Argon is mandatory to prevent embrittling nitride formation. For structural carbon steels, clean dry compressed air or commercial Argon/CO2 mixes can be employed, though pure Argon yields the highest weld pool fluidity and lowest porosity in deep keyhole modes. Coaxial gas delivery flow rates typically range between 12 to 25 L/min depending on nozzle diameter and travel speed.

Standard static focused laser spots have a beam waist of only 0.1 to 0.3 mm. If parts exhibit gap variations exceeding 0.15 mm, the laser beam will simply pass through the joint without coupling, causing burn-through or severe lack of sidewall fusion. Youmir's dual-galvo wobble welding heads introduce high-frequency beam oscillation (up to 500 Hz) in circular, sinusoidal, linear, or figure-8 trajectories across widths up to 5.0 mm. This dynamic scanning artificially expands the effective melt pool, bridging joint gaps up to 1.0–1.5 mm while simultaneously providing an active hydrodynamic stirring effect that releases trapped gas bubbles and dramatically suppresses solidification cracking in sensitive alloys.

For continuous wave (CW) fiber lasers in standard butt configurations: A 1000W fiber laser cleanly achieves single-pass penetration up to 3.0 mm in stainless steel, 2.5 mm in carbon steel, and 1.5 mm in aluminum. A 1500W system penetrates up to 4.0 mm in stainless, 3.5 mm in carbon steel, and 2.5 mm in aluminum. A 2000W system reaches 5.0 mm in stainless steel, 4.5 mm in carbon steel, and 3.5 mm in aluminum. Upgrading to 3000W allows robust high-speed production penetration up to 8.0 mm in stainless steel and 5.0 mm in structural aluminum alloys. Keep in mind that lap joints, fillet geometries, and reflective copper alloys require higher power density or tighter optical focusing ratios. We verify exact penetration thresholds on your parts prior to equipment purchase.

Yes. We routinely engineer turnkey systems featuring high-resolution coaxial CCD/CMOS cameras with crosshair reticles for microscopic part alignment and real-time monitoring. For high-speed robotic and gantry lines, we integrate structured laser triangulation seam tracking sensors mounted ahead of the welding torch. These sensors scan the incoming joint profile in 3D, compensating dynamically for thermal distortion, part stamped tolerances, and fixture clamping discrepancies in real time (X, Y, Z axis tracking accuracy within ±0.05 mm).

Standard catalog configurations (such as benchtop jewelry welders, 3-axis CNC workstations, and standard mold repair boom systems) typically ship within 10 to 15 business days from our Shenzhen factory. Fully custom automated cells with dedicated fixtures, multi-station indexing turntables, or robotic arm integration require 25 to 40 days for mechanical engineering, PLC programming, and rigorous 72-hour continuous burn-in testing. All machinery is sealed in anti-static vacuum foil with desiccant packs and crated in fumigated solid-ply export wooden crates designed for ocean, air, or rail transport. Every system carries a 24-month comprehensive manufacturer warranty on the laser source and primary motion components, backed by 24/7 remote video diagnostics and rapid DHL/FedEx spare parts dispatch.
