The present invention provides a method of sealing a round member (14) between flat members (16) having a first fluid path (25) that defines an inner diameter of the round member (14). This step includes positioning a round member between the flat members 16 to define the interface region 26, providing a fluid under pressure in the first fluid path 25, and Heating the interface region 26 to form a weld between the flat members 16. |
