High　speed　camera　and　data　acquisition　are　important　technology　to　research　the　dynamic　behavior　of　arc,　metal　transfer　or　weld　pool　in　welding　process.　A　synchronized　record　and　analysis　system　for　high　speed　images　and　process　parameters　was　established　based　on　the　synchronized　control　for　high　speed　camera　shooting　and　data　acquisition.　The　system　included　high　speed　camera,　synchronous　signal　generator,　high　speed　data　acquisition　device　and　synchronized　player　software　for　high　speed　images　and　waveforms.　The　dedicated　synchronous　signal　generator　is　adequate　for　synchronizing　and　trigging　high　speed　camera　from　20　to　200,　000　frames/s.　The　PC　based　data　acquisition　device　is　able　to　take　4　welding　parameters　synchronously　at　200　kHz.　It　was　demonstrated　by　the　experiments　of　several　typical　welding　processes　that　the　system　was　a　powerful　facility　for　recording　and　analyzing　the　dynamic　process　in　research　on　welding　material,　welding　process,　process　control　and　stability.
