Abstract (en)

The infulence of a welding current on the formation of weld is considered in the article. The advantage of welding by the modulated current determined out in comparison with welding by a direct current. It is determined that the high-frequency pulses of a current increase pressure of an arc, 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.
