Abstract

The invention provides a welding apparatus which can inhibit operation cost and improve productivity. The welding apparatus (1) comprises a vacuum chamber (100) having an internal vacuum environment, an X-direction welding unit (200). In the vacuum chamber (100), welding is conducted on a plurality of workpieces (10) along the X-axial direction, and the plurality of workpieces (10) are arranged in a rectangular shaft having X-axial and Y-axial directions. The welding apparatus (1) also comprises a Y-direction welding unit (300). In the vacuum chamber (100), welding is conducted on the plurality of workpieces (10) along the Y-axial direction.

Description

technical field [0001] The invention relates to a welding device for seam welding. Background technique [0002] Electronic components such as quartz resonators are manufactured by seam welding a cover (lid) as a lid (hereinafter, the package and cover are collectively referred to as a workpiece) or the like to the opening of the package (for example, refer to Patent Documents 1 to 3). Seam welding is performed by pressing a roller electrode against a plurality of workpieces arranged in a matrix in the X and Y directions, and rotating the roller electrode while applying a pulse-like voltage. [0003] Such seam welding is performed under nitrogen gas filled with nitrogen gas in the cavity, or under a vacuum environment in which the cavity is kept in a vacuum environment (approximately vacuum). Thereby, air can be prevented from entering the workpiece. [0004] In addition, after all the workpieces are seam welded along the X direction for each row in the X direction, all th...
