Weld joint between components for injection valve has protective medium applied as coating to region inside tubular component

摘要

The weld joint (31) is between a spherical component (21) and a tubular component (19), particularly in an injection valve. A protective medium (60) is applied as a coating to a region of the interior of the tubular component. The protective medium may be applied by means of application to the spherical component and subsequent centrifuging in the joint region.
