Przedstawiono wyniki badań procesu przenoszenia ciekłego metalu w łuku spawalniczym metody MIG. Obliczono równanie ruchu za pomocą wielomianu trzeciego stopnia dla pojedynczej kropli. Podano zmiany prędkości i przyśpieszenia w funkcji czasu, a tym samym położenia kropli w łuku spawalniczym. Wykazano, że metoda badania procesu przenoszenia metalu w łuku spawalniczym oparta na filtrze wąskopasmowym i bez konieczności stosowania lasera He-Ne jest bardzo użyteczną techniką.

The work reports the results obtained with using digital high speed video camera to investigate the metal transfer process in MIG welding. The mathematic description of droplet flight trajectory, droplet velocity and acceleration is presented. To calculate the droplet flight trajectory the polynomial regression of the 3rd degree was used. The new method of monitoring of the metal transfer based on the narrow band filter does not require He-Ne laser to observe the metal transfer. The method is cheaper and easier to use. The gained experience allows to direct further research on the metal transfer and possibilities of using this simple method for on-line monitoring of welding processes on automated and robotized stands.
