Abstract (English):
The paper reports the procedure of researches of welding bath parameters with the application of a high-speed video camera at laser welding. The video materials obtained allow monitoring on-line the parameters of bath crystallization and defining the dependence of this process upon welding speed. On the basis of the video material analysis there are defined dependences of bath parameter changes upon welding speed. There is shown a tie of changes in dimensions and micro-structure with the welding speed.

Keywords:
laser beam, high-speed video camera, crystallization, micro-structure.
