查询词典 metal wire

Through image digitalization and digital image frame analysis, the dynamic change of arc state and droplet motion before and after its detachment from wire tip can be quantitively described. The kinematical and kinetical parameters of droplet motion can be solved. The development of the system provides a new way for the study of metal transfer mechanisms and the interaction between droplet transfer and weld pool.
