Laser Hybrid Welding
Laser-hybrid welding combines a laser beam and an arc process in one common weld pool. It offers high speed and gap-bridging ability.
Physical-Chemical Mechanism of Action
The laser beam heats the workpiece very quickly, while the arc stabilizes the weld and bridges the gap. The high temperature of the laser ensures rapid deformation and bonding of the metals.
Metallurgical Relevance & Risks in Welding
This method is particularly useful for difficult materials or geometric shapes, as it allows high speeds and can bridge deeper gaps. However, inaccurate laser adjustment can lead to uneven deformation or excessive pressure, which can cause cracks or damage to the workpiece.
Workshop Practice & Instructions
To perform laser hybrid welding successfully, the laser must be precisely aligned with the workpiece. The arc currents must be stabilized and the laser speed controlled. Precise adjustment of parameters such as voltage, current, and temperature is crucial for a high-quality weld.
