Key Techniques on Design of Laser High-speed Video System for Recording Metal Transfer in Arc Welding

摘要：

The metal transfer process of arc welding with consumable electrode is a complicated procedure that combines momentum, heat and mass transfer as well as transportation. Due to the difficulties of observing fast changing process of melted drop transition, a proper high-speed video system with laser in the background was established for recording the process. Structure of the high-speed video system, design of optic system, selection of laser and preferences of camera lens which have influences on the recording results are introduced. The electrical waveforms and images of welding process were collected in synchronous with the system.
