Abstract: The present invention provides a method of sealing a rounded member (14), having a first fluid passageway (25) defining an inner diameter of the rounded member (14), between planar members (16). The steps include: positioning the rounded member between the planar members (16) to define an interface area (26); providing fluid under pressure to the first fluid passageway (25); and heating the interface area (26) to form a weld between the rounded member (14) and the planar members (16).
