Abstract
The method includes the steps of providing a first metal member and contacting the first metal member with a second metal member. A substantially cylindrical rotatable member is provided and is rotated while frictionally engaging it with the first metal member for locally heating and melting a portion of the first metal member, and penetrating the rotatable member through the first metal member. The rotatable member is rotated while frictionally engaging it with the second metal member for locally heating and melting a portion of the second metal member. A wire is fed through the axially extending passage and melted as it exits the axially extending passage. The resulting molten wire is mixed with the resulting molten metal of the first and second member, and solidified to form a joint.
