Double Wobble head technology

2-D dynamic beam motion

The concept of the 2-D dynamic beam motion or double wobble head technology. The six basic programmable shapes available from an industry-standard wobble welding head are shown. Independent control of the amplitude and frequency of the oscillation is achieved through a high speed servo controller, allowing more flexibility in stabilizing the keyhole melt during the welding process. 

Stability of the keyhole melt is a critical factor when laser welding dificult highly reflective materials such as copper and aluminum. This is partly due to the tendency to spatter, and in the case of some aluminum alloys, a high level of porosity due to the viscosity and surface tension of the melt when using more traditional laser welding techniques. Recent studies have shown the reduction or elimination of these problems with the beam wobble technique, including a recent systematic study with and without fller wire on automotive aluminum alloys.

Overall, the wobble head technique allows for better temperature management of the part. Because the beam passes near any given point of the weld multiple times, the ramp in temperature and cooling rates is slower than in traditional laser welding, which helps eliminate defects and manage spatter.  In addition, this welding technique is compatible with typical welding accessories such as assist gas ports and coaxial nozzles that enable plume suppression and can help control spatter; techniques that are not readily compatible with the scan heads used in remote welding.

In addtion to stabilizing the keyhole melt and reducing porosity in the subsequent weld, the beam wobble technique has proven valuable for alleviating the part-fit requirements for laser welding. Using one of the programable shapes (infnity in this case) and optimizing the amplitide and frequency of the oscillation, an increase in the acceptable seam gap of three times that achieved in conventional laser welding has been demonstrated.

Advantages of robot welding and manual welding in ONE machine

Manual welding still has a place in modern manufacturing industry. Manual welding is a good choice for projects that need to change welding methods quickly. A professional welder can quickly change what he is doing, but the robot can't adapt to the uncertain situation quickly. All manual welding is still a process that many companies need. 

Using the same laser source and cooling unit for automated or Robot welding can reduce drastically the investment cost. If your robot or automated machine need to work 24/24-7/7 on the production, then this solution is not a perfect one for you. If the automated production is only partial time frame filling, then the laser welding machine can be used as handwelding machine within 5 minutes modification of the laser head! 

Like this your welders can reach perfect weldings  much faster and with a much better result! This investment doubles your output possibilities!

Dual-axis handheld laser welding machine

Compared with traditional handheld laser welding machine, the welding advantages are obvious. The laser swing amplitude (range: 0mm-5mm) and swing pattern can be set through the control system during the welding process. The width of the weld seam can be customized through the swing amplitude, which solves the defect of traditional hand-held laser welding that requires high weld seams. Greatly improve the welding fault tolerance rate. Moreover, safety protection measures have been added, which only emit light to metal! The operation is simple and easy to use, the structure is simple and easy to maintain, the volume is greatly reduced, and the wire can be fed during the welding process, which is suitable for industry and household use.

Standard welding heads limits each setup to a specific application.

Wobble welding heads incorporate scanning mirror technology inside a standard weld head.

The wobble welding head is equipped with a rotating lens "weaving". By moving the beam with internal mirrors, the focal spot is no longer static, and can be dynamically adjusted by changing the shape, amplitude, and frequency of various patterns. This allows the laser beam to circle within a defined radius and makes it possible to reliably bridge larger gap sizes than were possible in the past. This both with and without a welding rod, even within the same part.
