FIELD: mechanical engineering; high-frequency welding of wall with web; manufacture of H-beams, sheet panels with stiffening ribs and other structures. SUBSTANCE: set is provided with additional member of special design installed for longitudinal travel. Member can be shifted in plane of wall of welded workpiece. Both displacements of member are carried out together with section wall. EFFECT: enlarged operating capabilities; possibility of welding of workpieces of any finite length with any shape of one of edges; prevention of mutilation of edge exposed to pressing force. 2 dwg
