Description

technical field [0001] The invention relates to the technical field of fuse additive manufacturing, in particular to an arc fuse additive manufacturing system assisted by an ultrasonic vibration coupled magnetic field. Background technique [0002] Arc fuse additive manufacturing technology is a wire-feeding metal additive manufacturing technology, which has the advantages of high deposition efficiency, material utilization rate, short manufacturing cycle, low manufacturing cost and large forming size range. With the improvement of manufacturing efficiency requirements for large-scale structural parts, fuse-type additive manufacturing has gradually attracted people's attention. [0003] However, there are also some difficulties in arc fuse additive manufacturing, which limit the application of arc additive manufacturing technology. First, the large arc heat input results in coarse grains. Larger temperature gradients lead to massive formation of columnar grains. Columnar ...

Problems solved by technology

For those parts that require comprehensive mechanical properties, it cannot meet its requirements

Secondly, the arc fuse additive technology is a thermal processing technology. During the additive process, defects such as micro-cracks, pores, and tissue disorder are prone to occur, and the residual stress in the formed part is relatively large. These factors seriously affect the performance of the formed part.

However, microscopic defects, structural state, residual stress, etc. are the main reasons for the poor performance of the formed parts. These problems will lead to a reduction in the service life of the formed parts, which will seriously affect the stability of the formed parts.
