Abstract
The pressure chambers (2) for the ejection of the ink are recessed in a body (9) of an ink jet printer. The chambers (2) are covered by a metal diaphragm (1). The pressure chambers (2) and the associated narrow passages (4) are formed in the body (9) by depression. Subsequently, the metal diaphragm (1) is connected to the body (9) by energy beam welding. The energy beam (31) is moved along the edges of the pressure chambers (2) and of the narrow passages (4). An electron beam or a laser beam may be used as the energy beam (31).
