System introduction
The HJK-SWIR online shortwave infrared thermal imaging camera enables real-time molten pool temperature monitoring during laser cladding 3D printing, penetrating laser reflection and plasma plume interference. It consists of a high-performance shortwave infrared detector, shortwave infrared lens, and signal processing circuit, and integrates advanced image processing algorithms. It solves the following pain points: intense laser reflection and plasma plume block true temperature measurement, rapid temperature fluctuations cause process instability, and lack of real-time feedback leads to inconsistent cladding quality.
Product features
1. It features all-weather passive thermal imaging capability, can see through glass, and operates over a wide range of ambient temperatures.
2. With a high frame rate design, the maximum frame rate can reach 125Hz, enabling observation of fast-moving targets.
3. It employs a self-developed temperature measurement calibration algorithm to achieve precise temperature measurement.
4. It outputs full-frame-lossless 16-bit temperature data and provides client software and an SDK development kit, facilitating secondary development and system integration by users, and enabling personalized temperature analysis of the target under measurement.
Application
The temperature measurement range is 600°C to 2500°C and its temperature measurement accuracy is ±1% or ±1°C.
It can be used for molten metal temperature, laser welding and 3D printing.
Equipment value
1. Real-time Full-field Temperature Monitoring
The infrared thermal imaging camera can simultaneously monitor the laser-affected zone and the surrounding heat diffusion, preventing localized overheating or underheating. Through temperature distribution maps, heat accumulation areas can be intuitively identified, allowing adjustment of laser power or scanning speed.
2. Optimization of Laser Processing Parameters
Different materials have different melting temperatures. The infrared thermal imaging camera helps determine the optimal laser power, scanning pitch, and exposure time. For example, in SLS printing, the thermal camera ensures uniform preheating of the powder bed and reduces thermal stress.
3. Defect Reduction and Improved Molding Accuracy
Through melt pool temperature field monitoring, infrared imaging can clearly display the melt pool shape and temperature distribution, avoiding overheating or lack of fusion defects.
4. Process Development and Quality Control
During the R&D phase, the infrared thermal imaging camera allows comparison of temperature distributions under different parameters, accelerating process optimization. In production, it enables automatic temperature alarms to ensure batch-to-batch consistency.
Case
Related Applications
The HIRDA-HT high-temperature resistant infrared thermal imaging temperature measurement and analysis system is specially designed for the glass furnace exit, which can work normally in a high-temperature environment of up to 500℃. It consists of an infrared thermal imaging core, an infrared lens, a high-temperature resistant water-air cooled metal protective cover, a thermal imager control cabinet and client software. It solves the following pain points: molten glass radiation and high-temperature airflow interference make it difficult to obtain accurate temperature, prolonged exposure to extreme heat accelerates equipment failure, and manual spot checks fail to detect temperature fluctuations at the furnace exit in time.
Built on its core infrared thermal imaging technology, HJK-FK is a series of intelligent monitoring systems designed for harsh working conditions such as high temperature and heavy dust. It extends the high-temperature resistant lens into the furnace through a telescopic device, while the core module is placed outside the furnace for real-time monitoring.
