| Summary: | Title screen In some cases, magnetic blow does not allow using direct current for shielded metal arc welding. This is especially true for repair work on pipelines after magnetic flaw detection. Alternating current is useful to control magnetic arc blow during welding. The most promising results give technologies using alternating current with a rectangular waveform. However, the advantages of this method have not been used until now. The main goal of this study is to determine the influence of the parameters of the arc on its stability and the metal transfer mode during shielded metal arc welding under perturbing action of the magnetic field. The proposed methodology of experimental research allowed identifying the cause of arc extinction using direct current electrode positive. This is due to displacement of molten droplets of metal by the magnetic field from of the uneven melted electrode coating and its subsequent separation. This problem was solved using alternating current with the square waveform pulse mode at a frequency of 500 Hz. The amplitude-time parameters of the current pulses provide stabilization of the arc and volume of the molten electrode metal. Режим доступа: по договору с организацией-держателем ресурса |
