Abstract
It was established that application of electromagnetic action is an effective method of degassing welds. The presence of extremum in experimental curves will make it possible to optimize the parameters of controlling magnetic field.
Keywords: underwater arc welding, low-carbon steels, electromagnetic stirring, diffusion and residual hydrogen, heataffected zone, structural transformations
