    • Abstract
  • High-speed photography is an effective testing instrument in welding arc physics research work,but current High-speed photography has not solved the problem of multi-signal waveforms synchronizing to photograph pictures.This paper has designed a High-speed photography with multi-information synch.Its data are sampled by using a fast data sample card of computer and corresponding sensors and its pictures are taken by using High-speed photography.A synch time mark is used as medium between photographs and signal waveforms.The principles of the device of the synch time mark maker and its interface to computer have been presented in detail in this paper.With the synchronizer this paper succeeds in validating the spectrum sensing of droplet transfer.Experiment results show that this synchronizer is an effective device,which would provide favorable means for welding arc physics research work.
