| Abstract: | A slow-motion video recording system for drop transition procedures of arc welding with consumable electrode is introduced. Matters with regard to lamp-houses and their selection, choice of lenses and light routing adjustment are explained. The determination for contents of optical enlargement ratio of laser shadowed image of melted drop, discrimination ability of a slow-motion video recording system, time of exposure and recording speed etc. are also clarified. The conclusions provide with high reference value on the technique of slow-motion video recording for melted drop transition procedures of arc welding with consumable electrode. |
