Abstract:
1. A method of magnetically forming a fluid joint comprising: inserting a first tube having at least one groove therein partially into a first fitting so that said first fitting partially overlaps said first tube; applying a layer of insulation onto said first fitting; inserting said first fitting in a metallic sleeve such that the insulation layer is disposed between said first fitting and said metallic sleeve; providing a magnetic forming system including an induction coil; inserting said first tube, said first fitting, and said metallic sleeve into said induction coil; generating an electromagnetic field; and imposing said electromagnetic field on said metallic sleeve to compress said metallic sleeve and cause said fitting to be compressed and formed at least partially into said at least one groove of said first tube to form a first fluid joint.
