Mergenthaler, No.1 in temperature controlled laser material processing

Dr. Mergenthaler High Speed ​​Infrared Pyrometers are characterized by their accuracy, speed and flexibility. They form a complete system of high-speed temperature data acquisition, closed-loop control, visualization, real-time storage and archiving.

Mergenthaler Infrared Pyrometer:
from 120 ° C to 2400 ° C in different measuring ranges (at 10,000 measurements per second)
For example: 120 ° C to 700 ° C, 350 ° C - 2300 ° C
(Special pyrometer from 70 ° C at lower measuring rates)
Software adjustable emission coefficient: 0.05 to 1.00

Application: Laser plastic welding, laser soldering, low-temperature measurements on metals


With the integrated temperature process controller laser sources or induction generators can be controlled. In this way, processes that were previously guided by constant laser power can now be optimized simply by specifying a processing temperature.

The system works autonomously: meaning, without PC connection, you can measure, control, store the temperature at a rate of up to 15kHz. With the software package LASCON® Process Manager you can visualize, parameterize and monitor your laser process. With a simple script language you can program and execute up to 256 different laser scripts. With these scripts you can monitor your laser processes 100% and have a traceability of your entire production.

Mergenthaler, No.1 in temperature controlled laser material processing

 

Dr. Mergenthaler High Speed ​​2 Color Pyrometers are ideal tools for temperature measurement on metals and many other surfaces. The advantages of 2-color pyrometers are that the measurement of the temperature is largely independent of the emissivity of the surface. In addition, in contrast to the infrared pyrometers, the measuring spot can also be smaller than the spot diameter of the pyrometer. 2-color pyrometers can also be switched to infrared (single color) pyrometers via software. All Mergenthaler pyrometers are supported by the same software LASCON Process Manager. This creates a complete system of high-speed temperature data acquisition, closed loop control, visualization, real-time storage and archiving.

Typical temperature ranges of the Mergenthaler Quotient Pyrometer (2-color pyrometer):
from 300 ° C to 2400 ° C in different measuring ranges (at 10,000 measurements per second)
For example: 300 ° C to 1000 ° C, 550 ° C - 2300 ° C

Even with unknown emission coefficients, 2 color pyrometers accurately measure temperatures on many surfaces.

With over 1500 industrial LASCON installations worldwide, Mergenthaler is the world market leader in temperature-controlled laser material processing.

Application for the Mergenthaler LASCON Quotient Pyrometers are:

Laser Cladding: Measuring the temperature of the powder coating to achieve a constant and homogeneous track width. In a closed loop controlled process, the slow heating of the workpiece during the process gradually creates an ever widening welding seam. This undesirable process is counteracted by the closed loop temperature control.

Laser welding: Temperature controlled laser welding of, for example, aluminum and composites Aluminum / steel composites are an example of applications for LASCON in laser welding of metals.

Laser hardening: A temperature-controlled laser hardening process is standard today. The laser control by means of a pyrometer compensates the different absorption behavior on the workpiece as well as the different heat dissipation by bore holes under the surface or edge effects. Mergenthaler LASCON systems with 2 colorpyrometers have been used worldwide for more than 15 years to control the temperature during laser hardening.

Annealing after laser hardening or welding to reduce material stresses

Additive manufacturing processes can be controlled by LASCON to control the temperature during the process. Therefore critical parts can be safely produced by controlling the critical temperature during the process.
