The Benefits of Wobble Welding Compared to Conventional Welding Methods

 Wobble modes

  • The welding heads equipped with the Wobble / Seam Tracking module have the following wobble modes available:


  • The wobble frequency and amplitude can be modified based on the application


 Weld Quality / Consistency

  • Compared to conventional (laser) welding methods, welding with the wobble option results in superior weld quality.
  • Wobbling also helps to overcome consistency issues related to back reflections when welding materials like aluminum, copper, etc.

 Materials Prone to Cracking / Porosity

  • When welded with conventional methods, some materials are sensitive to welding defects, for example:

–Some grades of aluminum that are prone to the pore formation during the welding process
–Spring steel which is sensitive to thermal cracking

  • When using the wobbler welding head, the welding process can be further optimized (various wobble modes, amplitudes and frequencies), so that the welding defects can be minimized or eliminated.

Welding Dissimilar Metals

  • When welding dissimilar metals, the wobbler has incomparable benefits, for example:

–If one material has a higher melting point or higher reflectivity than the other, the melting behavior of the materials can be “balanced” by choosing the wobble parameters appropriately.
–Some combinations of metals tend to form brittle intermetallic compounds as a result of welding. When using the wobbler, the melting / solidification of the intermetallic layer can be controlled better, which improves the weld quality.

Tolerance for Process Variables

  • As it comes to process variables, such as the gap between the workpieces, wobble welding allows a considerably wider process parameter window that results in good quality welds.

  • Example: Butt welding stainless steel sheets (thickness 1.5 mm):


A) Variation in the gap between workpieces   B) Offset from the center line between the workpieces
