Method and resistance welding device for bar and sheet-like semi-finished products

摘要

Resistance welding of rod and sheet blanks takes place by means of a welding machine (1) in which pressure on the blank is applied via the electrodes, and selectively means are provided for conveyance of the blank and/or the resulting component during mfr. The pressure on the blank is produced by converting - by means of at least one roller screw transmission unit (13) - a predetermined rotatory motion from at least one drive motor (11) into an axial motion and transmitting this axial motion to at least one electrode (8,9).
