Pulsed-arc welding is characterized by periodically varying arc power and due to its peculiarities it allows solving complex technology issues in development of unique structures, increasing the efficiency of welding processes, and depositing corrosion-resistant alloys on steel. At present, there is a great number of welding equipment manufacturers, who have introduced the ideas of pulsed welding application in their production. However, the data on the effect of pulsed-arc welding on the welding thermal cycles are of a fragmentary nature, and, therefore, it is difficult to compare the thermal cycles typical for stationary and pulsed-arc welding. In welding of high-carbon steels there is a problem of reducing weld metal mixing with base metal and the resulting increase of welded joint cold cracking resistance. Successful application of pulsed-arc welding for solution of the above-mentioned problems necessitated performance of comparative investigations of the effect of the modes of pulsed-arc welding on the parameters of welds, HAZ and welding thermal cycles in comparison with stationary arc welding produced with high-alloy welding consumables. This was the main aim of the investigations, the results of which are given in this paper. 31 Ref., 8 Figures.
