摘要

FIELD: manufacture by HF-welding of different thin-wall complex-shape articles, for example envelope parts. ^ SUBSTANCE: method comprises steps of placing welded blanks to action zone of magnetic inductor connected to magnetic pulse generator; restricting parts at side opposite to magnetic inductor by means of rigid support of insulation material; forming notches on welded surfaces of parts; overlapping welded surfaces one to other with overlapping zone exceeding value of notches; forcing welded surfaces of blanks one to other and to rigid support by efforts caused by interaction of magnetic fields of inductor and self-induced current occurred in blanks and heating them in welding places; realizing common fusion of blanks. ^ EFFECT: enhanced stability of welding process not needing complex mechanical attachments and large amount of energy. ^ 4 dwg
