Abstract
In a first embodiment, at a time of magnetic pulse welding, a stepped tube profile machining process axially bores a walled tube from an end inward to a transition depth to form a section with a reduced wall thickness and then axially bores the walled tube from the transition depth to a fall off depth, thereby forming a section with a maximized welding wall section. In a second embodiment, also at a time of magnetic pulse welding, a surface angle tube profile machining process axially bores at a surface angle a walled tube from an end to a bore length to form an angular welding wall thickness inward to a maximized wall section. For both embodiments, the bored surfaces are virgin with no pits, oil, residue, or oxidation thereon, thus making the machined walled tubes available for immediate magnetic pulse welding.
