Abstract
This invention relates to an apparatus and a method for manufacturing a member which makes a part of a car body of an automobile or the like by mash-seam welding a plurality of blanks. Standby areas (B) are provided at both right and left sides of an welding area (A) to/from which a seam welding machine ( ) moves forward/backward, and a lapping device ( ) for overlapping respective end portions of blanks (W )(W ) and a temporary clamping device ( ) for temporarily clamping the blanks (W )(W ) are disposed on two transfer tables ( ) which are sent from the standby areas (B) to the welding area (A) by turns. When the blanks (W )(W ) with these end portions overlapped one another and temporarily clamped are sent to the welding area (A) by the transfer table ( ), the blanks (W )(W ) are permanently clamped by a permanent clamping device ( ) and thereafter, subjected to a mash-seam welding by upper/lower electrode rollers ( )( ) of the seam welding machine At this time, upward reactive force which acts on a cylinder ( ) for pressing the upper roller ( ) downwardly is received by a frame structure ( ) which is installed in the welding area (A).
