Wobble Head Laser Welding

Wobbling the laser beam improves weld quality and finish and the seam tracker enables automatic adjustment of welding head lateral position when the seam location varies.

Wobble head laser welding.

Oscillation or wobble head laser welding was introduced. Wobble iv standard weld head wobble laser head autogenous welding additive welding. Laser welding of dissimilar metals is another difficult process area where the wobble head technology has shown significant potential such as welding stainless steel and copper figure 4a. The unit allows for simultaneous laser beam wobbling and welding seam tracking.

Wobble head technology is compatible with 12 kw power handling from. Ipg welding heads with wobble functionality deliver unmatched weld quality even. The wobbler improves welding process stability repeatability and the weld seam aesthetics. From welding highly reflective metals such as aluminum and copper to welding dissimilar metals linear joint pattern.

Melting and solidification of the intermetallic layer can be controlled with the wobble head technique to greatly improve weld quality between the two. Bm230 is simple flexible and easy to program control. The product is equipped with external servo motor and the maximum operating frequency is up to 100hz. Ipg photonics offers welding heads with integrated beam wobbler capability.

The module allows simultaneous laser beam wobbling and welding seam tracking. The wobbler controllably broadens weld seams created with high quality high power focused beams while reducing required laser power. The series of wobble welding head bm230 are released by switzerland raytools ag in 2016 which are suitable for medium power of fiber laser. We are analysing how the laser beam oscillation while welding allows attaining several productive and qualitative advantages.

The wobbler allows high quality welding even in the presence of some gap between the welded parts. Ipg wobble and seam tracking welding head adaptor integrates two technologies in one compact module. It helps manufacturers overcome common laser welding challenges. The laser beam welding is a well consolidated junction technique in industry and provides some advantages compared to competing junction technologies such as high productivity the possibility of welding without weld material and the limited heat input which results.
