【 摘 要 】

The procedure of calculating the parameters of the inter-pulse period such as current strength, electrode supply speed and time length is presented in the paper. Their importance for the stable arc burning is demonstrated. The authors address to the inter-pulse period parameters, influencing on the temperature of the electrode in the device, where the inter-pulse current is used for heating the electrode. The data of calculations are confirmed in the process of experiments. The appropriate parameters of pulsed arc welding with preheated electrode extension are identified; the stability of the process is tested experimentally: impulse frequency, inter-pulse period, arc voltage during the inter-pulse period, speed of electrode supply, current of the inter-pulse period.
