The features of formation of a ferrite band in vacuum impact and diffusion welding of low carbon steels were studied. It is shown that it forms as a result of several processes occurring at the stages of heating, upsetting and cooling. The mechanism of ferrite band formation is proposed as a combined action of the diffusion and recrystallization processes.
Keywords: ferrite band, vacuum diffusion welding, vacuum percussion welding
