Spot Welding and Seam Welding |
|
 |
|
From single spots up to seams of several metres length |
|
With laser welding it's possible to create single joining spots as well as welding in continuous wave mode |

The weld geometry describes how the parts fit together. For example, they may overlap or butt up against each other. The mechanical properties are the first thing to consider when defining the weld geometry.
Is a continuous weld required, or will the weld consist of individual welding spots? Is the weld made up of a large number of short lines or lots of small circles? Here, too, the decision on which type of weld to use depends on two important factors: the required strength of the weld and the maximum amount of heat input into the component.
Different kinds of joints require different operation modes of the laser device
Continuous wave modeIn this mode the gain medium is pumped continu-ously and emits a continuous laser beamPulsingIn pulsed mode, the gain medium is pumped in bursts to generate short laser pulses. Power, duration and frequency of the laser pulses are important parameters for material processing. |
