The Impact

This article deals with the development of shielded metal arc welding electrodes for P22/P91 welds. A comparison has also been drawn with commercially available electrodes. P22 low alloy steel matching electrodes developed in the laboratory using a mixture design approach was employed to fabricate the dissimilar weld. Experimentations were performed to evaluate the microstructure and mechanical properties of microhardness, tensile strength, and impact energy of the welds. The impact strength was found to improve by 19% for a laboratory developed electrode made welds as compared to the commercial electrodes. The weld chemistry investigations indicate that the weld fabricated with laboratory-developed electrodes have a higher amount of chromium and molybdenum. These elements are known to enhance the corrosion resistance of joint, thereby imparting enhanced structural integrity in high temperature operating conditions. The electrodes designed and developed in this work are found to enhance the properties of P22/P91 joint much better as compared to that with the commercial electrodes.

The Magnetic Field

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.
