Abstract

The influence of a welding current on formation of weld is considered in the article. The advantages of welding by the modulated current are found out in comparison with welding by a direct current. It is determined that the high-frequency pulses of a current increase pressure of an arch, its stability and penetration. The pulses of a current of average frequency operate carrying of electrode metal and reduce sputtering. The low-frequency pulses of a current (pulsation) influence liquid welding bath, improve formation of the seam and its structure. Ill. 5, bibl. 13 (in English; summaries in Lithuanian, English and Russian).
