Laser welding is the most advanced method of joining various types of materials and is particularly used when welding components where there is a focus on high welding speed while maintaining a precise, high-quality weld without cracks, dirt, pours and few thermal deformations of the surrounding material. The ThermoInspector has been deployed in several companies producing automotive parts that utilise laser welding. ThermoInspector is usually installed at the site of the manufacturing line where many individual plastic parts are all being welded. The welding temperature must be monitored at this stage of production as exceeding or not keeping to the welding temperature will produce a low-quality part. The low-quality part must be removed from production because it is not suitable for use or in extraordinary cases, if a low product containing the low-quality part is produced then the product may be destroyed during transport, assembly or use. This results in financial losses, reclaims and, of course, serious security risks. The ThermoInspector system helps to prevent all these risks.
For example, with one application of ThermoInspector during the production of components for the automotive industry, two plastic parts are laser welded. As this concerns welding using heat generated by the laser to join the two plastic parts, it is logically recommended (or is necessary) to check the temperature throughout the whole process. If the temperature is too low, the quality of the weld will be low, and the welded parts can separate. If the temperature is too high the production line can get physically damaged / interrupted and the laser beam will spark. In this scenario, the product would be excluded as defective and would go to waste.
