摘要:
A valve and a method for making the valve, the valve including a valve housing with a central part and with two connection ends, wherein internally of the central part there is arranged a valve body in a valve seat and connected to a valve spindle that is arranged in a spindle guide stub on the valve housing. The method includes a tubular workpiece being provided with a cutout, a plate-shaped workpiece being provided that is plastically deformed to form a collar on it whereby a spindle guide stub is formed with a collar along its lower edge and a cutout in its upper surface. The spindle guide stub is laser welded on the tubular workpiece providing an internal welding seam running along the edge of the inner opening in the collar of the spindle guide stub, along the cutout and at the outer side of the tubular workpiece.
