In-situ Process Monitoring
In-situ process monitoring is the real-time monitoring of the additive melting process using optical or thermographic methods. It allows immediate detection of defects and improves quality control.
Physical-Chemical Mechanism of Action
In-situ process monitoring uses sensors or cameras to continuously monitor the melting process during the build phase. Optical methods capture visual anomalies, while thermographic methods detect temperature differences.
Metallurgical Relevance & Welding Risks
This monitoring helps detect defects such as pores, deformations, or incompletely melted material. Without real-time monitoring, such defects may only be discovered after the build, leading to extra costs and material waste.
Workshop Practice & Action Instructions
To successfully use in-situ process monitoring, sensors must be correctly positioned and calibrated. Monitoring should be performed throughout the melting phase. If defects are detected, immediate correction or process abort must occur.
