FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to production of hollow articles with the help of diffusion welding. Blanks of skin and filler are made. Note here that separate ledges are produced on outer surface of one or both blanks to make thereof the article structural elements while continuous ledge is made in perimeter of working zone of one or both blanks. Then, blanks are assembled in a pack to be arranged between halves of female die so that blank working zone is located between appropriate halves. Pack working zone is compressed between die halves to heat said pack and to feed working fluid in closed chamber composed between die half and pack to develop pressure required for diffusion welding.
EFFECT: higher quality of joint.
