Adjustable magnetic field coupling and ultrasonic-assisted laser additive manufacturing and monitoring device

Abstract

The invention provides an adjustable magnetic field coupling and ultrasonic-assisted laser additive manufacturing and monitoring device. The device comprises a laser additive manufacturing system, a substrate, a magnetic field coupling assisted device and an ultrasonic-assisted unit. The substrate is mounted on an experiment support table. The laser additive manufacturing system is used for additive machining on the substrate. The magnetic field coupling assisted device is mounted nearby the substrate and is used for generating a magnetic field nearby the substrate. The ultrasonic-assisted unit is mounted at the bottom of the substrate and is used for generating ultrasonic vibration. The magnetic field coupling assisted device comprises a transverse magnetic field assisted unit and an axial magnetic field assisted unit. The axial magnetic field assisted unit is arranged nearby the substrate and is coaxial with a laser nozzle of the laser additive manufacturing system. The transverse magnetic field assisted unit is arranged nearby the substrate. By means of the device, the laser additive manufacturing machining quality and machining efficiency can be improved, and the shape of a molten pool, the height of a deposition layer and real-time change conditions can be monitored through a mobile monitoring device.

AI Technical Summary

Benefits of technology

This patented technology allows for precise measurement of shapes during metal forming processes that require advanced tools such as lasers. By utilizing this technology, it enables greater flexibility in terms of capturing diverse aspects of the surface being formed while maintaining good accuracy. Additionally, the apparatus includes a ring guiding rail mechanism that helps keep trackings from moving around inside the furnace without interferring with other parts' movement. Overall, these technical improvements help increase production efficiencies and enhance overall performance capabilities of laser melting systems.

Problems solved by technology

This patented technical problem addressed in this patents relates to monitoring the shape or size of a molted metal pool formed through laser Additive Manufacturing (LAM). Current methods involve observing only one aspect at once - either individually or collectively from multiple angles that can be influenced by any external factors like splashings, temperature changes, etc., which makes them challenging to interpret accurately.
