Dual-Axis Wobble Laser Welding Head

The dual-axis wobble laser welding head optimizes weld quality by moving the laser spot along two independent axes during processing. This advanced motion control reduces defects, ensures stronger seams, and adapts seamlessly to a wide range of materials.

With support for multiple wobble paths like linear, circular, infinity, triangular, and figure 8 pattern, the weld pool shape can be fine-tuned for maximum precision and consistency. These flexible modes enable stronger, cleaner welds with minimal post-processing.

Widely adopted in the automotive industry, dual-axis wobble welding heads are effective for demanding applications that require both structural strength and precision. Whether for thin sheets, dissimilar materials, or complex geometries, they provide the versatility and reliability needed to meet modern welding challenges.

Laser welding can be used across a wide range of metals, including carbon steel, stainless steel, aluminum alloys, and copper alloys. It also supports dissimilar metal welding, such as copper to aluminum or stainless steel to aluminum, making it highly versatile for different industrial needs.

The thickness that can be welded depends directly on the laser power. Higher power enables deeper penetration and thicker plate welding. When selecting a welding system, factors such as laser power, material type, and joint requirements should all be considered to ensure stable weld quality and efficiency.

A typical laser welding head consists of several key units:

  • Optical system: Lenses and collimators that shape and focus the beam
  • Swing mechanism: Dual-axis swing in some heads improves seam quality for different materials and thicknesses
  • Cooling system: Usually water or air cooling to manage heat during welding
  • Gas shielding system: Protects the weld area with gases like argon or nitrogen to prevent oxidation
  • Control system: Allows adjustment of focus, height, and swing modes for different applications
  • Connection interfaces: Link the welding head with the laser source, robots, or automated systems

Spot diameters usually range from 0.1 mm to 3 mm, depending on the laser source, optics, and application. Precision welds for electronics or medical devices often use ~0.1 mm spots, while thicker plates and large structures require >1 mm spots for faster speed and deeper penetration. Swing welding heads can dynamically adjust spot size during welding to optimize quality.

Yes. Thanks to its highly focused and non-contact nature, the laser beam can reach narrow gaps, deep recesses, and complex geometries where traditional torches cannot. Some models are also compact or include swing optics, making them especially useful for automotive manufacturing, mold repair, and precision component welding.

Compatibility depends on parameters rather than brand. The key factors are:

  • Laser interface/connector type (e.g., QBH, QD): Must match the laser source
  • Power rating: The head must support the intended laser power
  • Laser wavelength: Most fiber laser heads are designed for 1064 nm
  • Control protocol: IO, RS232, or Ethernet must align with the system
  • Cooling and gas connections: Fittings should match the overall setup

Tip: If you’re unsure whether your system matches, simply share your laser model, connector type, and control details with our technical support team, and we’ll confirm compatibility for you.
