Abstract: The present invention provides a method for connecting rounded members between planar members comprising the steps of providing a rounded member having an outer layer having a first melting temperature range and an inner layer concentrically disposed within the outer layer and having a second melting temperature range, the second melting temperature range being warmer than the first melting temperature range, providing a pair of opposed planar members, the planar members each having a melting temperature within the first melting temperature range, positioning an end portion of the rounded member between perimeter edges of the pair of planar members to define an interface area, applying pressure to the interface area to collapse the end portion of the rounded member to essentially a flattened position, applying sealing energy to the interface area to heat the rounded member to a temperature within the first melting temperature range but below the second melting temperature range, thereby forming a weld between the planar members, and the rounded member in the interface area, and, releasing the pressure to the interface area wherein the end portion of the rounded member returns to an open position.

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 round ed 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 (1 4) and the planar members (16).
