Wobble Head Laser Welding

Oscillation or wobble head laser welding was introduced.

Wobble head laser welding. Bm230 is simple flexible and easy to program control. The module allows simultaneous laser beam wobbling and welding seam tracking. Wobble iv standard weld head wobble laser head autogenous welding additive welding. Wobble head technology is compatible with 12 kw power handling from.

Ipg photonics offers welding heads with integrated beam wobbler capability. The series of wobble welding head bm230 are released by switzerland raytools ag in 2016 which are suitable for medium power of fiber laser. It helps manufacturers overcome common laser welding challenges. The wobbler improves welding process stability repeatability and the weld seam aesthetics.

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. The unit allows for simultaneous laser beam wobbling and welding seam tracking. From welding highly reflective metals such as aluminum and copper to welding dissimilar metals linear joint pattern. In this follow up article some of the specific application areas that benefit from the technique are described in detail including aluminum welding for automotive and difficult to weld dissimilar metal parts.

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. Ipg welding heads with wobble functionality deliver unmatched weld quality even. Ipg wobble and seam tracking welding head adaptor integrates two technologies in one compact module. The wobbler controllably broadens weld seams created with high quality high power focused beams while reducing required laser power.

The product is equipped with external servo motor and the maximum operating frequency is up to 100hz. Wobbling the laser beam improves weld quality as well as finish and the seam tracker enables automatic adjustment of the welding head s lateral position when the seam location varies. 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 wobbler allows high quality welding even in the presence of some gap between the welded parts.
