Dongguan 3000W Dual-Station Wheel Hub Spread Laser Welding Machine

Product Details

I. Core Parameter Analysis

• 3000W fiber laser : suitable for welding 3-8mm carbon steel/stainless steel wheel hub spokes, with a penetration depth of about 3-4mm (depending on the material and speed).

• Selectable pulse/continuous mode : Continuous laser is suitable for high-speed welding, while pulse mode is suitable for thin plates or high-precision welds.

• BPP≤2.0mm·mrad : High beam quality ensures a focused spot diameter ≤50μm, improving energy density and making it suitable for narrow weld seams (0.1-0.3mm wide).

• Carbon steel : 1.5-3m/min (3mm plate thickness); Aluminum alloy : needs to be reduced to 0.8-1.5m/min (requires the use of a swing head with anti-air holes).

• Dual-cycle water chiller : Temperature stability ±1°C, ensuring that the laser does not reduce power during long-term operation.

II. Key Configuration Recommendations

• IPG/Chuangxin fiber laser : Preferred single-mode fiber (such as YLS-3000), electro-optical conversion efficiency >30%, lifespan 100,000 hours.

• High dynamic galvanometer welding head (such as Precitec YW50): integrates coaxial vision to track the wheel hub weld trajectory in real time, with a repeatability accuracy of ±0.03mm.

• Oscillating function : The frequency can be adjusted up to 500Hz to improve the fluidity of the weld pool in aluminum alloy welding.

• Six-axis robots (such as Kawasaki and Yaskawa): 60kg load capacity, ±0.06mm trajectory accuracy, and multi-angle welding can be achieved when paired with a positioner.

• PLC control system : Supports Modbus TCP protocol and is compatible with MES system for tracing welding parameters.

III. Key Points of Wheel Hub Welding Process

• Aluminum alloy wheel hub (A356-T6): Laser cleaning (150W pulsed laser) is required to remove the oxide film. Argon gas protection (99.999% purity) is required during welding.

• Stainless steel wheel hubs : Nitrogen protection is used to suppress spatter, and silver-white weld seams are preferred.

• Porosity suppression : Dual-beam technology (3000W main beam + 500W auxiliary beam for preheating) is recommended for aluminum alloy welding.

• Crack prevention : Carbon steel wheel hubs need to be preheated to 150-200°C (for thick plates).

V. Recommendations for Acceptance Standards

• It meets ISO 13919-1 Class B standard, with an X-ray detection porosity of <1%.

• Tensile strength ≥ 90% of the base material (for aluminum alloy wheels, it must reach 250MPa or above).

• Welding continuously for 8 hours, with power fluctuation < ±2% and scrap rate ≤ 0.5%.

VI. Extended Applications

With slight modifications, this equipment can be used for:

• Battery tray welding (aluminum alloy stacking welding, high sealing requirements)

• Drive shaft welding (deep penetration welding, penetration depth must reach 8mm)
