Custom Multifunctional Laser Welding Machine Manufacturer & Pricelist

The multi-process capability is governed by optical beam divergence adjustment and nozzle geometry conversion. To switch from welding to rust/paint cleaning, the operator exchanges the copper wire-guiding nozzle for an ultra-wide focal cleaning nozzle and switches the touchscreen CNC program to "Cleaning Mode." This shifts the internal collimating and focus lenses, increasing the beam sweep from a 0.5–5.0mm wobble pattern to a 10–120mm line or raster scan. Switching to cutting requires installing a high-pressure coaxial cutting tip and setting the shielding gas to dry compressed air, nitrogen, or oxygen at 10–15 bar pressure. The complete switchover takes under 60 seconds without requiring specialized optical cleanroom environments.

Pulsed laser cleaning utilizes Q-switched or MOPA fiber architectures that emit short bursts of laser energy with gigawatt peak powers over nanosecond pulse durations. Because the thermal diffusion duration is shorter than the thermal conduction time of the metal, the targeted oxide layer vaporizes without introducing thermal strain or melting the underlying substrate. It is mandatory for precision injection molds, aerospace turbine blades, and historic artifacts. Continuous Wave (CW) laser cleaning utilizes an uninterrupted high-average-power beam (1000W to 3000W); it produces higher thermal input into the base metal, making it ideal for rapid, heavy-duty rust, mill scale, and paint removal on thick steel plates, structural beams, pipelines, and automotive frames where minor surface melting is acceptable.

Gas selection dramatically influences keyhole ionization, weld oxidation, and penetration depth. For Stainless Steel (304, 316), high-purity Argon (≥99.99%) or industrial Nitrogen (≥99.995%) is recommended; Nitrogen preserves austenite phase balance and improves surface hardness while Argon yields brighter silver-white beads. For Aluminum Alloys (5000/6000 series), ultra-pure Argon (≥99.999%) or an Argon-Helium mix is critical to prevent hydrogen entrapment porosity. For Carbon Steel, pure Argon or standard Nitrogen prevents surface scale. Pure Helium provides optimal plasma plume suppression and deepest penetration, but its high commercial cost typically reserves it for specialized aerospace titanium or nuclear alloy applications.

Yes. Joining copper to aluminum is traditionally difficult due to the wide divergence in melting temperatures and the formation of brittle intermetallic compounds (IMCs like $Al_2Cu$ and $AlCu_3$). Youmir’s multi-axis automated CNC cells solve this through dual-axis wobble beam scanning and offset beam positioning. By focusing the fiber laser spot preferentially into the lower-melting-point aluminum while utilizing the high thermal conductivity of copper as a heat sink, molten aluminum wets the solid copper surface, creating a metallurgical braze-weld interface. This reduces brittle IMC layer thickness to under 5 microns, preserving electrical conductivity and mechanical shear strength in EV battery tab joints.

Unlike TIG welding which continuously burns non-consumable tungsten electrodes and requires extensive filler rods, fiber laser consumables are minimal:

• Protective Cover Windows (Fused Silica): Replaced every 2–4 weeks based on spatter conditions ($3 – $8 each).
• Copper Welding Nozzles: Replaced every 1–2 months ($2 – $5 each).
• Wire Feed Tips: Standard wear item ($1 – $3 each).

Operating electrical costs for a 1500W system total roughly 4.5 kW/hr (including chiller and controls), translating to approximately $0.60–$1.20 per hour in power. Adding shielding gas (Argon at 12–15 L/min), the total operational cost typically runs under $3.50 – $4.80 per hour, yielding dramatic operating margin gains compared to manual arc welding.

We provide a 2-year warranty on laser generators and major optoelectronic components. Every machine features modular component interconnects. If a fault is diagnosed via our 24/7 remote optical telemetry, we dispatch a replacement core module via expedited international air courier (DHL/FedEx) within 24 hours. Because the optical fiber, water hoses, and electrical connectors utilize standard quick-disconnect fittings, swap-outs are completed by plant operators in under 30 minutes following our step-by-step video procedures. Furthermore, we maintain authorized spare component hubs in select regional centers across Europe, North America, and Southeast Asia.
