Heat conduction welding

 

The term “heat conduction welding” comes from the way energy is transferred into the material – namely, through conduction.

In heat conduction welding, the laser beam melts the base material along a joint. The resulting molten material flows together and solidifies to form the weld. This technique is used especially for laser welding thin-walled components. Weld depths are usually up to about 0.5 mm, and the width of the weld is greater than the penetration depth. Intensities usually range up to 100 kW/cm².

Compared to deep penetration welding, heat conduction welding boasts higher speeds but lower intensity. This allows for especially flat, rounded weld seams. Touch-ups are not necessary. Both pulsed lasers and continuous beam lasers can be used for heat conduction welding; however, typically solid-state lasers are used.

Heat conduction welding is often used in the household appliances, medical technology and electronics industries.
